Intermap Expands Online Offerings

Intermap Technologies Corp. (CO, USA) has expanded its online offerings to include countrywide and state-wide SRTM (Shuttle Radar Topography Mission) elevation datasets, contours and Global Mapper geospatial software. All of these offerings complement the Intermap suite of NEXTMap digital elevation models.

SRTM elevation datasets will supplement the company's NEXTMap high-resolution datasets while the company collects and builds their national elevation database of countries around the world. The SRTM datasets are available by whole country or group of countries (except for the United States, which is broken into states and territorial islands). The datasets have national boundaries buffered to 12 nautical miles, ocean elevation set to 0 metres and flattened lakes greater than 600 metres in length. Datasets are available in ESRI GRID format or custom formats at a customer's request.

The U.S. state and territorial island models are clipped from SRTM DTED Level 2 data using ESRI's shapefiles of U.S. state boundaries. Country models are clipped from the SRTM DTED Level 1 data by using ESRI's international country shapefiles.

Intermap's contours, generated from its bare-earth Digital Terrain Model (DTM), are available at various intervals, depending on the customer's application requirement and the terrain characteristics of the area of interest. Contour datasets are available throughout Intermap's DTM areas.

Additionally, Intermap has also added Global Mapper software to its online product offerings. Global Mapper is a software package for the analysis and viewing of geospatial data. Global Mapper allows users to apply GIS functionality to raster, elevation and vector datasets and offers conversion, editing and printing capability. A three-dimensional viewing tool is also included.
