Real estate broker National Land Realty is using Esri's ArcGIS platform to advance the process for identifying land parcels suitable for solar energy development. The online mapping system incorporates data from utility company maps, topographical information and local government land information. "In the past, you might have an analyst creating these maps and sharing them as a PDF. Now, you can share data into the cloud, have it password-protected, opened. They can pull in these layers, it opens up more possibilities," said David Beitz, president of Beitz and Daigh Geographics, which helped create the system.
