1 CHARLIE 15 MINUTES ABSTRACT In this session, we show how you can use a map template and other resources from the Resource Centers to complete your work faster and easier. We will touch on managing and organizing your data for cartographic data management, but we focus on graphic design for special kinds of maps and how this design can be facilitated and standardized using map templates. In particular, we will tour map templates that can be used to design geologic, hydrologic and 3D maps. These demonstrations will help you see how you can use map templates to standardize your production processes and your map designs, thus making your life easier! We also show you related resources that are available to your though ESRI s Resource Center web site that will also increase your mapping productivity and the quality of your maps. 3D Map Templates producing videos, setting the scene for the video (people), and more. Hydrologic Map Templates flowline tapering, labeling hydro features, hydro with DEMs, and more. Geologic Map Templates line symbology, labeling, map finishing with carto reps for special features, the geology map as an overlay erlayon a basemap, and more. 1

2 We want to point out that you don t need to take lots of notes because we ll be positing this presentation on our Mapping Center Web site on the Other Resources page. The bottom notes will have everything we are going to say. So, in this presentation, you can sit back and focus on the concepts and demos about mapping with ArcGIS. We ll show these URLs again at the end of this talk. But now, let s get started. 2

3 Through the examples, we ll show you how you can use them. 3

4 What is a map template? It s a of resources for making a map. It includes useful examples that convey the design of a map. It embodies the map specification. The intent was to deliver an example of that map so that you could see what it contains. If you have a basic background din ArcMap, you can use these to see how you can deliver a given kind of map. Each of our map templates is designed for a specific purpose. As all maps have a specific audience and purpose, the map templates are defined the same way with a specific purpose and audience in mind. What is different from other map specifications is that you don t need to read a specification document and figure out how to apply it in ArcMap it is already applied and you can use it to rapidly see how you can use it with your data and how you can use it to create a new implementation for your data. 4

5 View the gallery of templates Go back to the home page and look at the stuff in left margin: Live Training Seminars Best Practices Mapping Center blog and Ask a Cartographer 5

6 This graphic shows you in general what is in a map template. You should always open the Getting Started document so you can see what is in the template and how to use it. Applications folder: Web applications or any other type of application that also has the source code. Documentation: More in depth information about how we created certain cartographic effects or processes so that it does not overload the Getting Started document. X ray tools read the key properties of the layers and the map document so you can find out abut the contents. 6

7 What we have learned is that this is a way to share practices and methodologies so that you can share how you work within an organization or even between organizations. This is faster and simpler than writing up a doc and trying to share that. They can be used to learn about cartographic design, workflows and ArcGIS methods. Templates are also flexible they are not standards. Instead you should look at the template to see how what we have delivered to you can be modified to reflect what you do within your organization. You can think if it as a starting point, not an ending point. You can also use them to learn about how to make maps you have not made before. For example, maybe you have not yet made a trails map and you can use the template to kick start that map making process. If you have not yet made any online multi scale maps, the map templates can really help you get started quickly. The point is that we are giving people who already have maps and a workflow in place something that they can use to generate ideas, think about new mapping approaches, etc. They may not use it right away but they can use it to generate discussion. Getting started with this type of map Solution is presented to you Refine the maps you already make Use these additional resources to get ideas and to achieve cartographic effects Examples: San Antonio, TX Bexar County, TX 7

8 We have a Live Training Seminar to show you this in more detail. 8

9 These are basic instructions to download the map template and view the contents of the download. The first thing to do after that is to open and read the Getting Started document. You can then open the.mxd and the geodatabase and see what they contain. view the contents of the sample GDB, open the.mxd and view the contents of the ToC, open the layers and view the properties (symbology, labeling, display, etc ). You can either change the source to point to your data or you can apply the symbols, labeling, etc. to your own data. 9

10 We are going gto show you handful of map templates that we have either already started or we are in the process of working on. We have these map templates or we are in the process of working on them, so these are the ones we are going to show you. One thing to point out is that this set of map templates will demonstrate capabilities for making print maps, online maps and ArcGlobe documents. We ll start with Geology this is the first one we started. It relates to the FGDC standards and it demonstrated for us that we could meet the specs of the FGDC to deliver the solution. This was first possible in 9.3 because we had the capabilities of Maplex and cartographic resources. Now we ll have Janel show you the template. 10

12 Geologic maps serve many uses. They are used in everything from mineral exploration to reference maps; serving as what we call an operational layer or simply a basemap. They also serve as the foundation for derivative products, such as landslide analyses maps. 12

13 Although they serve many purposes, p most geology gymaps represent similar features including geologic units, faults, contacts. This map template allows you to use standardized symbology across all maps that meet the FGDC Digital Cartographic Standard for Geologic Map Symbolization specifications. 13

14 Traditionally, geology gymaps were published as a print product, on one or more large sheets of paper. Digital publication, in the form of coverages, shapefiles and geodatabase are now the norm for the distribution of the geologic map. A new development is the publication of geology maps online. The Geologic Mapping Template provides the tools to publish a map in any format. 14

15 The geologic g map template is an ArcGIS implementation of the FGDC Digital Cartographic Standard for Geologic Map Symbolization. It contains a geodatabase, geology symbols, tables, tools and documentation. These resources allow the geologic map maker to follow a consistent and efficient methodology for publishing geologic maps. Not just about symbolizing your data this is a complete data model for geologic mapping. 15

16 The geodatabase feature classes and representation classes of the template database follow the logic of Appendix A of the FGDC standard. So, there is a feature class for each section of the Appendix. For example, there is a contacts feature class, a faults feature class and a bedding feature class. Each of these feature classes also has a representation class associated with it. These representation classes are where the symbols for the geologic features are stored. These symbols are known as Cartographic Representations and are simply an advanced ArcGIS symbology option. Cartographic Representations were the only way implement the precision of the FGDC Standard s symbol specifications. The only way to implement cartographic representations is in a geodatabase. The feature classes in the template database contain the required fields and symbols to support the advanced cartographic tasks associated with plotting geology symbols on the map. Take inclined bedding features, for example. They require an angled symbol and a rotating label to properly represent the strike and dip of the observed feature. The bedding feature class contains the fields to capture this information so that the symbol can be properly plotted on the map. 16

17 ArcGIS Online Explorer demo of U.S. Geology done using the template. This example showed 10+ datasets that had been downloaded from the USGS and State Surveys and published as map services after working through the steps outlined in the Geologic Mapping Template s Getting Started document. 17

18 This shows different images from the ArcGIS Online Demo of the geology map services that were made with the geologic map template. The data in these maps were downloaded from the USGS and State Surveys and added to the template database that is included in the geologic map template. The tools and the tables in the template made it possible to crosswalk data in different schemas into a single data model for the purposes of making a geology map using a standardized workflow that can be replicated from one data set to the next. 18

19 Geologic symbology is exacting and complex, requiring the use of cartographic representations to create the advanced symbols that appear on a geology map in ArcGIS. Cartographic representations allow for greater precision, data driven placement of symbols and labels, the ability to modify symbol geometry without modifying the underlying feature geometry and making cartographic refinement tasks possible. I ll Ill demonstrate these capabilities in a demo/following slides. 19

20 ArcMap Demo. Summary of demo in subsequent slides. 20

21 Note the difference between the dash and line marker symbols between the two. The triangles hover off the dashed line in the left image where the thrust fault has been symbolized with the default, Geology 24K Style. The image on the right shows how the triangles follow the curvature of the line and remain on the line. The direction of the triangle is significant as well. The FGDC Standard specifies the use of the right hand hand rule when adding an ornament, a triangle in this case. The symbols in the Geologic Mapping Template follow this logic in that the symbol is designed so that the triangle will be placed to the right relative to the line moving from the from node to the to node. 21

22 Geology symbols sometimes require refinement to complete the symbol definition. For some line symbols, this can be done with the addition of a control point in an edit session using cartographic representations. The strike slip fault in the example above shows the line symbol before and after the addition of a control point. 22

23 In most cases, a complete symbol for inclined structures include a shaft that is plotted at and angle to represent the strike of an observed feature. The label for the symbol should be placed at the symbol s dip tick or at the arrow end of a linear feature; the label being the observed dip or inclination value. To work with rotating symbols and label placement, the structure features classes (bedding, cleavage, foliation, etc.) in the template database have two fields to drive this information: SymbolRotation ti and LabelRotation. ti The Geologic Mapping Template tools calculate the appropriate symbol and label rotation values based on the strike value. A style file for Maplex labels contains a style for orientation point symbols that automates labeling. In the example above, the left image shows inclined bedding before the symbol rotation value has been calculated. The center image shows the inclined bedding plotted after the symbol rotation value has been calculated, but before the label rotation value has been calculated. The right image shows a completed symbol with the symbols and labels properly plotted based on the value calculated for the symbol and label rotation. 23

24 If Maplex is activated, then you can apply the Orientation Point label style that is included in the Geology_Template.style. This automates 85% 90% of the label placement process! 24

26 Stay tuned for updates and additions! 26

27 This was a project we started two years ago to help one of our customers distribute info about water networks and water observation networks online. The diff between this and the geology template is that there was no spec so we were developing the template on the fly. Caitlin is going to show you where we are with this project. Her goal is to deliver a template to show how to make this hydro basemap especially at larger scales to help contextualize site or project specific hydro information. 27

29 Thanks, Charlie! Some of you are probably familiar with our standard basemaps, that we provide for free on ArcGIS.com to our User Community such as 29

30 the World Topographic p Map, 30

31 the World StreetMap 31

32 and the World Imagery map. 32

33 The Hydro Basemap is our newest edition to this collection, and it was built specifically to support hydro data layers. Just like the other basemaps it can be wired in to your web applications or desktop applications, and then used as the foundation for your hydro specific maps. 33

34 The Hydro Basemap template is also available to our users, and can be found on the Hydro Resource Center in the fall. The template is a useful tool for designing your own hydro rich basemap using your data. And it can be the base for operational data layers, such as stream gauges or flood zones in a simple mash up. 34

35 The Hydro Basemap highlights g hydro features, and so we made some design choices aimed at doing just that. Using the NHDPlus dataset to display surface water, and the NHD Hydro Units dataset to display catchment boundaries, we have a strong set of hydro features on our basemap. We symbolized the streams and rivers to give a tapered effect, and also came up with some labeling rules to allow an appropriate amount of text to be displayed on rivers, streams, lakes and ponds. Now, let me take you through a short tour of these design choices using ArcGIS Explorer. 35

36 As I mentioned earlier, the map contains a rich set of hydro features including rivers, streams, lakes, ponds, swamps, marshes and playas. The rivers, streams, lakes, and ponds are symbolized with light shades of blue. And notice that the labels are colored in a slightly darker blue so that they stand out and can be easily read while also showing that they are related to the water feature. You can see that the swamps, marshes, and playas are symbolized using lighter shades of green in an area pattern. 36

37 Other supporting hydro information present our basemap is the NHDPlus hydrologic units, which you can see here displaying with dark brown boundary lines. The Hydro units display regions, basins, and sub basins based on the NHD Plus dataset. You will notice that t the basin names are present, also in brown. As you move through scales, you will see that the basin names change, moving from region name at the smallest scales to sub basin name at the largest scales. 37

38 We kept the cultural information on the map to a minimum so as not to distract the map viewers from the water features being highlighted. So, as you can see, we use lightly drawn political boundaries, and roads to keep this information in the background and allow the hydro features to stand out. For example, you will notice that the urban areas are only evident by the feature label placement and size. The actual urban area shapes are not present on this type of basemap. 38

39 We designed this map with a transparent background to make the basemap more flexible In this example, you can see that the basemap is displaying on top of a terrain surface, and here, we add a thematic polygon layer, and still the hydro features are clearly displayed. This is a mean annual flow by HUC unit thematic polygon layer. 39

40 Now, notice the shape of the streams on the basemap. They are tapered, meaning that the width of the line is based on symbol classes that were derived from mean annual flow values in the NHDPlus attribute table. Or more simply put, the wider the stream, the greater the mean annual flow value in the attribute table. The tapered streams effect gives the map reader an immediate impression of flow in streams without looking at all at the attribute table. An added bonus is that since we are using consistent flow class symbology, we can also make comparisons of flow in streams across the United States. So, when we look at our map at the current scale, we know that there is more mean annual flow in the Mississippi River than there is in the Missouri River, and that there is even less in the North Platte River. 40

41 Still looking at our streams, we can see that the label sizes also vary. Again, we used mean annual flow values, but this time we set up a label hierarchy. So, the larger the stream label the greater the mean annual flow value in the attribute table. Infusing relevant information, such as mean annual flow, into the layer s symbology and label properties increases the value of the map because the map reader can immediately infer additional information about the streams without having to look at the sometimes complex attribute tables. 41

42 One last design choice I would like to talk about is another labeling effect. This time on surface water polygons. Lakes, and other surface water polygons come in all shapes and sizes. So, labeling these features in a standardized way can be difficult. For the Hydro Basemap we used a methodology for correct label placement based on polygon shape types. We have a lot of information about this topic on Mapping Center. But, the basic idea is to group polygons into shape categories (Long, round) and these categories work in conjunction with the Maplex Label Engine. So, curved streams have curved labels, round streams have horizontal labels, and polygon like features will get horizontal labels. This allows for all the labels on the map to be dynamic, so no annotation is required. Here is a good example of correct label placement on some lakes. Lake Josephine. That was our tour of the Hydro Basemap using ArcGIS Explorer Online. Now let s go into ArcMap, where I will show you how to reproduce some of the cartographic effects I just went over. 42

43 Let me first show you how we symbolized the streams in our basemap to get the tapered lines effect. You will remember that the width of the stream lines is relative to the Mean Annual Flow values in the attribute table. So, let s open up the layer properties of our flowlines, and go to the Symbology tab. Here, we can see that the correct value field is displaying in this case our mean annual flow values. So, the smaller streams with less mean annual flow are symbolized using a thinner line, and the larger streams with greater mean annual flow, are symbolized using a wider line. 43

44 Next, we will look at the stream labels. So, let s open Label Manager and check out the label properties of the flowlines. We can see a number of classes in here, and each class has different properties. We set up label classes as a way to display the stream size according to mean annual flow values the same concept as the tapered stream lines, except here we are using label classes and SQL Queries to create different categories for the labels. So, you will notice as I move through these classes that our smallest mean annual flow class have a text size of 8.5 points, while our largest mean annual flow class has a text size of 12 points. 44

45 We set up the classes using SQL queries. So, as you can see here we are using the FlowClass field to apply a query, so that only those records that fit the query will show labels in that particular class. In this label class, we want the largest streams with a flow class = 5 to have the largest font size of 12 points. And, in our smallest label class, we want all streams with a flow class greater than 11 to have the smallest sized text of 8.5 points. 45

46 The last topic that we will briefly take a look at is the labeling methodology for polygons. As I said before, the idea is to have Maplex use the general shape of the polygon so that the correct label placement can be applied. And there are materials on Mapping Center website that go into more detail regarding how those shapes are determined. What I am focusing on today happens after the polygon s shape s have been classified. So, now we are looking at our Waterbodies layer, and let me just show you the definition query, by going to Properties, then the Definition Query Tab. This expression looks a bit complicated so I encourage you to take a look at the documentation on Mapping Center. However, what this definition query does, is displays the shapes in a way that jives with Maplex. And so we can see when we look in Label Manager, at the NHD Waterbodies Label Class, that nothing out of the ordinary had to be done in order to get the label placement right. By using the expression in the definition query, we are able to use Maplex as usual to display our labels. Now, let s go back to PowerPoint for our summary. 46

47 In summary, the Hydro Basemap is a flexible, simply pydesigned base layer for use with hydro data. We hope you will take these design considerations and cartographic effects and create your own Hydro basemaps. 47

48 Looking ahead The Hydro Basemap and template are available on ArcGIS.com and the Hydro Resource Center in the fall. We hope that you take advantage of these mapping products, and create your map templates that you can share on ArcGIS.com. com In the coming months, we will be releasing additional hydro map services and applications on ArcGIS.com, so stay tuned. Now Charlie will introduce the last map template. 48

49 Mapping is not just about a 2D map anymore we wanted to work on this for a while we hired Craig this year to help us develop a 3D map. One of his first assignment was how to present a 3D city. And it was really about how to feature contents within the 3D city. The city is the basemap and you are featuring things in the city. I ll let Craig show you some of what he s been working on and what some of the next steps will be for him as well. 49

50 CRAIG 18 MINUTES 3D templates provide a data framework and guidelines for creating, analyzing, and delivering your own 3D city content in ArcGIS 10. The templates follow the standard file structure, except our viewing environment is ArcGlobe. Relevant example data is included in the template. In this demo we ll be looking at data we have for the city of Philadelphia, PA. 50

51 First, the 3D templates provide guidelines for incorporating and exploring your existing data in 3D, as well as creating 3D data from scratch. Examples: DEMs, LiDAR, orthoimagery, 3D multipatch buildings, operational layers (trees, street furniture, etc.) District of Columbia has made available all structures within the district as multipatches, Esri s 3D geometry file type (as seen in screenshot). As more city/state governments provide such data, the easier it is to quickly create a realistic 3D visualization of your town. 3D templates use a standard data model, so you don t need to rely on ad hoc solutions to effectively manage the data in your 3D GIS. 51

52 Once you have your data, what do you do with it the second part of the story is analysis. ArcGIS 10 brings a suite a new tools for analyzing your data within a 3D context. Examples include visual sensitivity analysis, such as line of sight, shadows, skylines. We can also calculate 3D intersections between features or use network analysis tools to analyze routing and connectivity in a 3D network. If we need to adjust our data to re run an analysis task, we can now interactively create and edit features in 3D using ArcGlobe or ArcScene. 52

53 In delivering your story a site visit/walk through or the results of your analysis 3D has a lot to offer compared to traditional 2D maps: Texture of buildings and the structural hierarchy/visibility relationships Limited use of abstract symbology symbols mimic the real life objects they represent, less need to consult a map legend Not limited to top down views, seamless transition from global to local to street level scales 3D provides an opportunity to develop best practices in our cartographic representation 3D cartography is a relatively new concept. 53

54 3 Layer types in the Table of Contents: elevation, draped, floating Building features use a combination of 3D multipatches and 2D footprint extrusions (building heights calculated using LiDAR data). Distance based visibility for buildings is set in layer properties to 1km to optimize performance. Operational layers (traffic controls, signs, etc.) use common attributes: Type, Specific, Rotation & Size. Type (Sign), Specific (Stop Sign), Rotation (45 degrees), Size (3). For trees, it is suggested that using the random value option for symbol rotation for a less ordered and more natural look. Same is true for symbol sizes set a minimum and maximum size value and each feature will be given a random value within that range. Labeling options include: dynamic labels, 3D graphic labels. The type of labeling you use depends on the scale of your visualization. Example: city scale view, dynamic labels are optimal. At the street level, may make sense to move to 3D graphic labels. 54

55 The 3D templates are effectively guides for building your own 3D city starting with creating and formatting your data, through to analysis and finally delivering a story to your audience. 55

56 Looking ahead, we re setting up a 3D Resource Center where you ll find future 3D templates as well as various tips & tricks for working effectively in 3D. Each of these templates will focus on how to create and manage different types of 3D content. 56

57 Upcoming template: creating your own multipatch features. One example is the overpass, where DEMs typically do a poor job of capturing the relative elevations of road surfaces. Start with a polygon and a swatch of imagery end with a 3D overpass with a void space underneath. 57

58 ArcGIS Server: creating your own 2D basemap service for your 3D visualizations allows you to customize the look and feel of your 3D city. Perhaps you want to create a more schematic city view, as seen here, using data from the DC Data Catalog. 58

59 We ve also been developing workflows for creating 3D building interiors. Each of these examples began with a set of CAD drawings: the one on the left is the building at ESRI where the Mapping Center team is located. On the right is the San Diego Convention Center showing the transportation network used in the web routing application to navigate between UC sessions. ArcGIS 10 brings a lot of new functionality in 3D visualization and analysis and we re excited to bring these tools to our users so they can build great 3D maps! 59

60 CHARLIE 2 MINUTES You ve seen three templates some are done and some are still in progress. Already have GMT, and we are creating the others. 60
