ExsaMap is a Jakarta, Indonesia, based company specializing in the generation of map products using Interferometric Synthetic Aperture Radar (IFSAR) as a primary source of data. These products, comprising digital elevation models, orthorectified radar imagery, and topographic maps of Indonesia are available for purchase to the public and the geospatial community.

ExsaMap was formed in 2004 to fulfill the map generation needs of the NEXTMap Indonesia program, as well as to support other commercial editing requirements of Intermap Technologies Corporation. Sponsored by Intermap, the NEXTMap Indonesia program was launched in 2003 to provide a consistent 3 meter (RMSE) elevation model and radar imagery over most of Indonesia.

Over the next few years, depending on demand, the NEXTMap Indonesia dataset will continue to grow , with the ultimate goal of building a complete, national dataset of elevation and imagery data.
