The company offers satellite and airborne data and product supply; Global Seeps Database, geological interpretation, onshore mapping, airborne lidar and aerial photography, ice monitoring and mapping, drainage mapping, pipeline planning and digital terrain models.
The surveying activities will provide basic topographic data; LiDAR digital surface models (DSM), digital terrain models (DTM) and orthophotos, for a project constructing a new oil and gas pipeline in the area.
With V8i, the bridge modeller is able to orchestrate many types of civil model data, including importing alignments, vertical profiles and digital terrain models from any of Bentley's Microstation-based civil software.
HEC-RAS and the following GIS-based tools may be applied to achieve this linkage: (i) a procedure to delineate watershed boundaries and stream networks extracted from a digital elevation model (DEM) in GIS (Jenson and Dominique 1988); (ii) the ARC/HEC-2 procedure, which links the HEC-2 model with Arc/Info (Beavers 1994); (iii) the ArcView extensions AvRAS, (ESRI 1998) and HEC-GeoRAS (USACE 1999), which enable physical element descriptions in HEC-RAS to be transferred to GIS software; and (iv) a methodology that integrates a digital terrain model (DTM), in the form of a triangular irregular network (TIN), with HEC-RAS single-reach geometry data (Tate 1999).
The firm also pioneered the combined use of hydraulic models, 3-D elevation contour data and digital terrain models to compute flood elevations and map inundation areas.

Intermap's NEXTMap database includes digital surface models (DSMs) that include cultural features such as vegetation, buildings, and roads; digital terrain models (DTMs) with all cultural features digitally removed; and orthorectified radar images (ORIs) that accentuate topographic features - all with a vertical accuracy of 1 meter or better.
