Castle Consulting (U.S.) was the first company in the world to focus primarily on Geographic Information Systems (GIS) applications in the real estate industry. As an unabashed champion of the benefits of GIS technology, Castle Consulting throughout its history has balanced – in equal measure – consulting engagements, customized system development projects, and educational activities.

(If Horace Greeley were alive today, his advice would most likely be “Go east, young man!”) Accordingly, Castle Consulting India was founded in 2009 to provide the GIS-related products and services described at this Web site, for clients in India, the United States, and the rest of the world.
