Consider the benefits of immediate access to the best-of-class 3D terrain information for the world. Intermap Technologies®’ NEXTMap® database provides optimized, multi-sensor-derived digital elevation data and orthorectified radar images to enable accurate geospatial analyses in any area of interest.

Digital Surface Model
Our NEXTMap digital surface model (DSM) is a first-reflective-surface model that contains elevations of natural terrain features in addition to vegetation and cultural features such as buildings.

Digital Terrain Model
Our NEXTMap digital terrain model (DTM) is a bare-earth model that contains elevations of natural terrain features such as barren ridge tops and river valleys. Elevations of vegetation and cultural features, such as buildings and roads, are digitally removed.

Both digital elevation models that Intermap offers are seamless, wide-area, and current terrain data so you can perform more accurate cross-border geospatial analyses in applications. Our NEXTMap DSMs and DTMs are available in two versions.

    Hydro-enforced digital surface model – structures over water bodies (such as bridges) are removed, water surfaces are flat, and watercourses flow downstream – making them ideal for water resource and floodplain management applications.
    Ortho-ready digital surface model – bridge decks are maintained in the elevation models, and major roads are smooth to accommodate the use of the surface models in orthorectification of optical images.

Orthorectified Radar Image
Our orthorectified radar image (ORI) is produced from our proprietary interferometric synthetic aperture radar (IFSAR) sensors and provides an image in regions where there is persistent cloud cover. The orthorectified radar image is a grayscale radar image of the earth’s surface that has been corrected to remove geometric distortions caused by terrain.

The orthorectified radar image accentuates topographic features such as rivers, road networks, and vegetation boundaries. Many geospatial applications can be supported by our orthorectified radar image, including topographic and geological mapping, land coverage classification, and forestry analyses.
