The Landscape Modeler application that I’ve been working on was presented during the plenary session of the 2013 Esri International User Conference. Lanscape Modeler is a JavaScript application that enables ArcGIS Online users perform weighted overlay analysis with the new landscape datasets that Esri is hosting on ArcGIS Online. The application is able to perform real-time weighted overlay at scales ranging from that of a city to the entire country by leveraging the ability of ArcGIS image services to apply raster functions on the fly.
Below is a video of the quick 2 minute run through that Suzanne Foss presented in San Diego where she demonstrates how to use the application to develop a conservation plan for an area outside of Santa Cruz:
The app will be released in the coming weeks, so stay tuned.
