How do I publish my maps on the web to share them with other stakeholders?

There two ways to publish and share your maps on the web. One way is to contact the DEA GIS staff to request the development of a web-based GIS application. Upon completion of the GIS application you can share the application's web address with other stakeholders. The second way is to use the free ESRI's web-based applications by uploading your map service and share with our stakeholders. These applications are called ArcGIS Map Viewer and ArcGIS Explorer Online. Video tutorials for the use of each of these applications is available on the tutorials website.

What is the difference between the maps posted on this DEA GIS website with the maps posted by the Google Earth application offered by the Division of Transportation System Information (TSI)?

The DEA GIS website illustrates GIS web-based applications that are developed using the Adobe Flex API and the ESRI's ArcGIS server. ESRI in most of the cases utilizes the Microsoft Bing Maps for the background imagery. Since the GIS applications posted by DEA are web-based, no installation is required. Google Earth (GE) is a desktop application that it requires the installation of the Google Earth software on the workstation. The GE is based on Google maps and it hosted by the Division of Transportation System Information. For more information on the Google Earth application click here.
