Elevation data is an essential piece of GIS data for hydrologic applications, but it’s big, not always easy to get and for modeling surface water flow requires specialized processing to become useful. Elevation data and services are coming to ArcGIS Online, including some hydro specific capabilities.
World Elevation Services
The World Elevation Services became available for beta testing last fall and will be released at the end of March. There are image services, data download services, and analysis task services available, as well as sample applications. The services are built from a collection of data sources, ranging from less than a meter resolution up to almost 5 kilometers, and includes services of elevation, shaded relief, slope, and aspect. We will continue to add new data as it becomes available. Like other things on ArcGIS Online these services can be used in Desktop and any other Esri clients, and also in other applications via REST or SOAP. http://resources.arcgis.com/content/imagery/10.0/world_elevation
Since you’re reading the Hydro Blog, your obvious thought is, when can I start using elevation web services for water resources applications? You’ll be happy to know we’re working on it. You’ve probably noticed a shift happening in ArcGIS Online and the Resource Centers to more specific application areas, in places like ArcGIS for Local Government and right here for Hydro.
