Free Digital Terrain Model of Vietnam  

   

 

 

For the first time in Vietnam, users of Geographic Information Systems (GIS) can utilize Digital Terrain Models (DTMs) for the whole of the country. This dataset is freely available from the internet as a public domain dataset. Anybody can download tiles of DTM data – as shown beneath.

To save you time and trouble, GEOBIZ have already downloaded all 53 SRTM tiles (see text box at foot of this document for more information concerning the SRT Mission) - and can supply the SRTM data free with every purchase of Vertical Mapper, thus providing any Vietnam user with a base grid for draping satellite images and aerial photographs of any part of Vietnam.

To provide you with a glimpse of the possibilities, displayed below are some screenshots of DTMs created in Nghe An province, using the public domain SRTM dataset in combination with MapInfo’s Vertical Mapper.

The Shuttle Radar Topography Mission (SRTM) obtained elevation data on a near-global scale to generate the most complete high-resolution digital topographic database of Earth. SRTM consisted of a specially modified radar system that flew onboard the Space Shuttle Endeavour during an 11-day mission in February of 2000.
SRTM is an international project spearheaded by the National Geospatial-Intelligence Agency (NGA) and the National Aeronautics and Space Administration (NASA).

GEOBIZ can supply the SRTM data free with every purchase of Vertical Mapper, thus providing any Vietnam user with a base grid for draping satellite images and aerial photographs of any part of Vietnam.
 

MapInfo Vertical Mapper is a robust grid-based analytical application. Grids represent data that vary continuously from one location to another, such as elevation, temperature or average family income. By analyzing data in a grid format, users can easily view constantly changing data variables in relation to location by thematically mapping the data with color or relief shading, or by layering and comparing the data mathematically with other grid themes to determine unique or hidden relationships. Vertical Mapper provides robust grid generation, display and analysis capabilities. The product can be deployed along side MapInfo Professional or MapInfo MapX. Version 3.0 of MapInfo Vertical Mapper offers major enhancements in data analysis, editing and output generation.
