DENVER, Colo. (April 26, 2006): Intermap Technologies Corp. (IMP:TSX) has expanded its online offerings to include countrywide and statewide 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 meters and flattened lakes greater than 600 meters 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.
