2 GIS Tool for integrating data from disparate sources. A set of tools for spatial analysis. It s not just a map! A set of tools for document and data management. Digital light table, planimeter, ruler, calculator. A tool for sharing data inside and outside of DOTD, across departments and to the public. Solutions to your daily business problems. GIS is a Solutions Tool!

3 Presentation Overview Presentation topics: What is GIS? What is an Enterprise GIS? Other GIS Resources DOTD GIS Resources

4 What is GIS?

5 What is GIS? It is not just a map! It is a system of software, data, maps, network locations, internet services, models, work flows and procedures. database database

6 What is GIS? At the core is the ArcGIS Software, which is a toolset (like Microsoft Office). The software displays maps, which are tied to database tables. But that is just the beginning.

8 GIS and CADD GIS maps are not just graphics. They are data. CADD GIS A rich collection of graphics Geospatial Reference Layers do not interact no topology No geospatial reference Data Display and Analysis Ad hoc applications Ability to create new information combining data from disparate sources.

9 GIS and Visualization GIS compared to visualization - consumer mapping products such as - Bing, Google, Yahoo, Map Quest and others. Consumer Mapping Optimized for display Static data canned base map No geoprocessing (analytical capabilities) Limited access to geospatial functions (geocoding and routing only) GIS Optimized for Display Dynamic data over a static base map Dynamic symbology Rich geoprocessing and analytical functions Ability to create new information from disparate data sources

10 GIS and Visualization

11 GIS: Software- Data Tools - Sharing The software accesses map layers and database tables. The software gives the user tools to ask questions of the maps Which schools are within ¼ mile of an interstate? How many miles of state roads are in Orleans Parish? Which state roads are used for sugar cane trucks during sugar cane season? Query results are combined into new information. Any map and any query results can be published to the web for the public or to an intranet site for DOTD. If you can make a map of it, it can be put on a website!

12 What is GIS? It is a tool for accessing information across the entire DOTD enterprise and information from other state agencies. What current projects are in Senate District 25?

13 What is GIS? It is a system that combines data from disparate sources to create new information. Are there any oil fields near this construction project (will truck traffic be a consideration?)

16 What is GIS? It is a set of tools for measuring and analyzing data. Throw away the light table, the planimeter, ruler, and calculator. It s all in GIS! Debris Removal

17 What is GIS? It is a tool for performing spatial analysis. Extracting information and deriving solutions by analyzing the locations and the data related to those locations. In which parishes are there roads with high average daily traffic? How many miles of road have high ADT?

18 What are the Parishes with the Highest ADT? Step1 - Select by Attribute, from the STL, the highway segments with ADT > 100,000 Step 2 - Select by Location, the Parishes, using the previously selected highway segments where ADT > 100,000 Parishes with ADT > 100,000 BOS CAD DOTD District 04 DES SBN RDR DOTD District 08 BRG CLC DOTD District 07 NCH VRN CMR CLB BNV ALN JFD LNC JCK WIN GRT UNI RPD EVN ACD OCH CTH LSL VRM CLD AVY MRH SLN RCH FRL TNS SMT IBR DOTD District 05 PTC SMY MDS DOTD District 58 WFL IBV DOTD District 03 DOTD District 62 EFL EBR SHL LVN TRB TNG LFU WSH STM ORL DOTD District 02 PLQ SBR Bossier Caddo East Baton Rouge Jefferson Orleans West Baton Rouge

19 What are the Parishes with the Highest ADT? Perform a Spatial Join to summarize the ADT statistics on highway segments falling in each Parish The result is a Parish dataset with attributes containing rthe summary statistics from the highway segments in that Parish CLB UNI MRH BOS LNC CAD OCH RCH BNV MDS JCK DES RDR CLD FRL TNS WIN NCH LSL CTH GRT SBN RPD VRN AVY WFL EFL SHL WSH EVN BRG ALN SLN PTC EBR TNG LVN STM CLC JFD ACD SMT IBV ORL CMR VRM SMY LFU IBR TRB PLQ SBR Legend Average ADT by Parish Average ADT / Road Mileage

20 What is an Enterprise GIS? One software, one database, one set of maps, all shared across DOTD. An Enterprise GIS allows for and encourages: Interoperability Consistency Universal access to data across the entire organization Data and mapping standards

21 IT GIS Staff maintain a GIS Database and a set of GIS maps and procedures. Data is shared with mobile apps GIS staff publish maps via ArcGIS Server and share data via SDE to DOTD staff and to the public, via ArcGIS datasets or and ArcGIS Online Enterprise GIS DOTD staff, staff from other local, state and federal agencies and the public access the maps and/or data layers and tools via web browsers, data viewers and/or the ArcGIS Software suite. GIS data is stored on LADOTD servers. Data from other state and federal agencies may also be incorporated in the shared maps Data Exchange

22 Why Enterprise GIS is Important Enterprise GIS creates a common operational picture across the organization that facilitates: Universal access to the technology Multiple levels of technology support different levels of use All levels of technology interact seamlessly Universal access to the organization s data Universal access to support by users Enterprise GIS supports one version of the truth and promotes the flow and integration of data across the organization

23 Who uses the Enterprise GIS? An Enterprise GIS accommodates different levels of users. LEVEL 0 LEVEL 1 LEVEL 2 Casual user accesses GIS with visualization tools. Occasional user of map data. Accesses GIS via canned maps and desktop applications. Regular user of GIS, works with data on a GIS map to develop ad hoc analysis, create new information from existing data and access data from the enterprise database and web services. LEVEL 3 Advanced User, regularly performs sophisticated spatial analysis and modeling, and creates new data.

24 Level 0 Users The public, DOTD, other local, state and federal agencies can access any number of web applications served via ArcGIS server without knowing anything about GIS. LEVEL 0 Casual user accesses GIS with visualization tools. Web maps are pre-defined. Users can pan, zoom and turn layers on and off but have limited access to add their own layers from the DOTD GIS database and web services.

25 Level 1 Users Occasional users of GIS data can access canned maps via ArcGIS Explorer, ArcGIS Online and web maps. LEVEL 1 Occasional user of map data. Accesses GIS via canned maps and desktop applications. Users start either with a generic basemap or a LADOTD base map, and can easily add additional data layers from the DOTD GIS database. Simple analysis is performed.

26 Level 2 Users Some users benefit from accessing GIS from the ArcGIS software. Those users are people who: Need data from a GIS map on a regular basis Want to do ad hoc analysis Need to create their own data These users usearcgis Desktop (usually the Basic license level) and access GIS data from SDE and/or ArcGIS servers. LEVEL 2 Regular user of GIS, works with data on a GIS map to develop ad hoc analysis, create new information from existing data and access data from the enterprise database and web services.

27 Level 3 Users Individuals who accomplish a major portion of their work using ArcGIS Advanced. These users Create new data Edit the enterprise data Perform complex analysis Produce sophisticated cartographic products Advanced User, regularly performs sophisticated spatial analysis LEVEL 3 and modeling, and creates new data.

28 Who is using GIS? Many local, state and federal agencies share GIS data, including: DNR - SONRIS DEQ Make a Map State Lands State water-bottoms. USGS - National Hydrography Dataset (NHD) USGS - National Elevation Dataset (NED) NRCS (National Resources Conservation Service) - SSURGO FEMA Flood Maps site, MapMd site Bureau of Ocean Energy Management (BOEMR and BSE)

29 Who is Using GIS? Private industry: Engineering, surveying and construction Oil companies Marketing companies Local water, electric and gas distribution companies Cell phone companies Local Government: School districts (bus routing, attendance zones) Long-range planning Assessor s offices Police, fire, and emergency response Levee Districts Hospitals Everybody!
