HimalayanTOPO DEM – Digital Elevation Model of whole Himalaya

 

dem07Our Digital Elevation Model of the whole Himalayan region is compatible with all major GPS software products like QuoVadis(R) or Global Mapper(R). It covers the complete Himalayan region including Nepal, India, Sikkim, Pakistan, Bhutan and Tibet.

The DEM data can be used to view 3D data, enhance existing 2D maps with elevation data, create nice maps with hill shading etc. (functionality depends on your GPS software).

Furthermore we inlcude a detailed vector data layer of contour lines at an interval of 20 meters! The contour lines were created from the DEM data and very high level of detail. You can use this layer as an overlay of existing raster maps or to create own vector maps from sources like OpenStreetMap or similar. The data can be used in QuoVadis and Globalmapper only (for other GPS software the data has to be converted before usage).

With your purchase you will be able to download the data in different file formats, so you can choose the fileformat which is best for your GPS software.

Data source

The basis of our Digital Elevation Model is the 3 arc seconds data set collected by the 2000 Shuttle Radar Topography mission (NASA/USGS SRTM3).

This data was enhanced and corrected by Jonathan de Ferranti from Viewfinder Panoramas with other topographic sources like raster and paper maps. Therefore the data from Viewfinder Panoramas is the best DEM data available for the Himalaya region.

The data from Viewfinder Panoramas was slighty corrected and enhanced by HimalayanGPSMaps in 2016.

 

Data format:

The package contains  the Digital Elevation Model (raster) as well as a vector layer with contour lines at an interval of 20m. The following file formats are included:

  • DEM: Global Mapper(R) Grid (.gmg format), best for Global Mapper(R) and QuoVadis(R)
  • DEM: GeoTIFF (.tiff format)
  • VECTOR: Global Mapper(R) Package (.gmp format)
  • VECTOR: QuoVadis(R) Map Vector (.qmp / .qmv format)

 

Map Coverage:

The DEM and vector layer with contour lines at an intervall of 20m cover the whole Himalaya region. Exact coverage is:

  • Upper left corner longitude: 54° 12′ 12.0094″ E
  • Upper left corner latitude: 43° 54′ 39.1155″ N
  • Lower right corner longitude: 107° 38′ 09.0094″ E
  • Lower right corner latitude: 0° 41′ 32.8845″
