Arc GIS Basics I 9:15am to 9:45am This exercise familiarizes you with some basic features of ArcGIS and illustrates some fundamentals of GIS. You will work with map layers and underlying attributes data tables for U.S. states, cities, counties, and streets. All layers you will use are made up of spatial features consisting of points, lines, and polygons. Each geographic feature has a corresponding data record, and you will work with both features and their data records. Learning Objectives Open and save a map document Work with map layers Navigate in a map document Measure distances Data: Data for this entire workshop under C:\Sowmya\UCLSFallForum2014 Open and Save a Map Document Launch ArcMap 1.

Add Data US States US Cities NOTES: Work with Feature Attributes What are features: What are attributes: Graphic features of map layers and their data records are connected, so you can start with a feature and view its record. You can also find features on a map using the feature attributes. Identify Tool: To display the data attributes of a map feature. This is the easiest way to learn something about a location on a map Zoom to the full extent of the map On the tools toolbar, click the Identify button. Click on the state of Utah. The state temporarily flashes and its attributes appear in the Identify dialog box. In the Identify window, click the Identify from drop down list and click US States Click the red circular point marker for OREM Make sure the point of the arrow is inside the circle when you click the mouse button. Notice which feature flashes that is the feature for which you get information Continue clicking a few other cities to see the Identify results. Hold down the Shift key to retain information for more than one city. Then click the name of a city in the top panel of the Identify window to view that city s information. UVU GEOMATICS Page 6
Select Features You can work with a subset of one or more features in a map layer by selecting them. For example, before you move, delete, or copy a feature you must select it. Select features appear highlighted in the layer s attribute table and on the map. Zoom to the full extent of the map From the Tools toolbar, click the Select Features button Click inside Utah. This action selects Utah and highlights it with a blue outline. Hold down the Shift key and click inside the four states adjacent to Utah (Nevada, Idaho, Colorado, Wyoming) Clear a selection Click, Selection, Clear Selected Features Alternatively, you can hit the Clear Selected Features button (next to the Select Features button) NOTES: Work with attribute tables What are attribute tables? Open the attribute Table Right click the US Cities layer in the TOC Click Open Attribute Table o The table opens, containing one record for each US City point feature o Every layer has an attribute table with one record per feature Scroll down in the table until you find Chicago and click the record selector (gray cells on the left side of the table) for Chicago to select that record UVU GEOMATICS Page 7
TIP: If a feature is selected in the attribute table, it also is selected on the map In the table, click the Clear Selected Features button Get statistics You can get descriptive statistics, such as the mean and maximum value of a non string attribute, in ArcMap by opening a map s layer attribute table using the Statistics function Zoom to the full extent Right click US States in the TOC, click Selection, and click Make This The Only Selectable Layer Hold down the Shift key and use the Select Features tool to select the state of Utah and the four states adjacent to it (Nevada, Idaho, Wyoming, Arizona) In the TOC, right click US States Click Open Attribute Table Right click the column heading for the POP2000 attribute Click Statistics.

Export the layer into Google Earth Let s Begin Again Launch ArcMap Click Start, All Programs, ArcGIS, ArcMap 10.1 Open MappingProject_UCLS.mxd This project map documents contains the following LandOwnership PLSS_AGRC UtahCities Counties TURNGPSSensorMap Task 1 Importing Excel Sheets (GPS Control) Into ArcMap Surveying control stations for your firm is normally saved to a excel sheet. This will contain the GPS x, y and z values. In addition, it may contain the year this control was surveyed/revisited, Crew chief name, etc. Import the excel sheet MyOfficeControls into ArcMap. The important attributes in this excel sheet are as follows: Station ID X Coord Y Coord UVU GEOMATICS Page 12
Year Surveyed (2003 2014) Crew (X or Y) Let us import the given excel sheet into ArcMap Add Data Double click MyOfficeControls.xlsx, ProjectControlsTable$ Right click ProjectControlsTable$, Display XY Data Choose the following and hit OK In the TOC, move to the List By Drawing Order tab Right click, ProjectControlsTable$ Events, Data, Export Data, Browse Button Save under MappingProject folder as ControlStations.shp A new shapefile called ControlStations in now added to your map document Change the symbol to something nice UVU GEOMATICS Page 13
Task 2 TURN GPS Network Buffer Distance Map You may have to check the accessibility to the TURN GPS Network around your survey site before you leave from office. To accomplish this task, we will adopt buffer rings. This procedure, creates buffer polygons around input features to a certain distance. Let us create buffer rings around all the TURN GPS locations with a radius of 5 miles. Make sure your TURNGPS layer is turned on Geoprocessing, Buffer o Input Features: TURNGPS o Output Feature Class: Buffer_TURNGPS o Distance: LinearUnit (Radio Button) Type in 20 Change the Units to: Miles o Dissolve Type: ALL o Leave the rest at its default o Hit OK o This step will take upto 5 minutes. Please be patient! Task 3 LandOwnership Symbology Map Practise Time! Task 4 Analysis Let us choose to select only the Crew Chief X s control stations (since he is managing his worksflow and getting ready to send out his team again). This data is located in the ControlStations attribute table. Create a new shapefile/layer of only the Crew Chief X data (We will later create a map of just these control stations and export to Google Earth). UVU GEOMATICS Page 14
Go to Selection, Select By Attributes o Layer: ControlStations o Method: Create a new selection o Double click on CREW o Click = o Hit the Get Unique Values button o Double click X o Hit OK or APPLY/OK 26 of 45 records are selected. Where to find this? In the TOC, right click ControlStations, Data, Export Data UVU GEOMATICS Page 15
Save the new layer as CrewXControlStations Juncture Summary: The above step created a new shapefile using the selected attributes Clear Selection. Turn off ControlStations Task 5 Label Features Let us label CrewXControlStations using the Year attribute. Practise Time! Also label the Counties layer using Name attribute Task 5 Create a Map The most important task for the day is to put all these data together as a map with all the necessary elements. Include the following information in your final map (layers in the same order) CrewXControlStations UtahCities Buffer_TURNGPS Counties LandOwnership Change the transparency for Buffer_TURNGPS (75%) and Counties (55%), by going into Properties, Display, Transparent for each of the two layers. Add a Title: MyGISProject, North Arrow, Scale Bar, Scale Text, Text (for your Name), Legend, Any Picture (If needed), etc. UVU GEOMATICS Page 16
Task 6: Export the layer into Google Earth BONUS Time: This exercise will walk you through the process of loading your shapefiles in Google Earth. Google Earth reads the shapefile only in kml/kmz format. There are open source tools available online. But there are tools available in ArcGIS 10.1/10.2. The utmost important fact is that Google Earth is in the geographic WGS 1984 coordinate system. So all shapefiles should be projected to this coordinate system before converting to a kml/kmz file. Google Earth Pro reads a shapefile (vector format) or images (raster format) easily. Unfortunately not all organization and individual users are at the mercy of the Google Earth Pro! These files can be shared with a mobile user or on the go. Data: The data for this step in located under GoogleEarth folder. Open GoogleEarth.mxd. This contains the Cities and Counties layers. Let us import each of these layers into Google Earth format. Turn the label on for Cities (if not turned on) Proceed to ArcToolBox - Conversion Tools To KML Layer to KML (since one individual layer is converted) UVU GEOMATICS Page 17
Layer to KML dialog o Layer: Cities o Output File: Cities.kmz (make sure to save under GoogleEarth folder) o Check Clamped features to ground (optional) o OK. Please be patient! Wait until a pop up with a green check shows up at the lower right corner of your Arc Map. Open Google Earth (From Start Windows) UVU GEOMATICS Page 18
UVU GEOMATICS Page 19
In Google Earth, File Open Proceed to where the kml file is saved. Select Cities.kmz Wait for this to show up on Google Earth (be patient ) WARNING Once you close Google Earth, the data just added (KML) will be deleted. So move the KML file from Temporary Places (Left side window in Google Earth) to My Places. So the data is locally saved in this computer. Practice: Follow the above procedure to convert Counties to Counties.kmz Summary & Conclusion This material should have provided an individual with the basic concepts and fundamental analysis using Geographical Information Systems. Hope you all enjoyed the workshop. Come back for more THANK YOU! UVU GEOMATICS Page 20
