Global Mapper Forum is pleased to offer the 30 Meter National Elevation Dataset available to you on 2 highly-compressed formatted DVD-ROM’. Unlike other companies where you have multiple CD’s or even worse a hard drive version.

This latest break through in our GM Grid format compression technology creates major significance
of time saving results for you in reference to:

-Loads your data more quickly

Ability to reproject and convert any other format in Global Mapper

The data is provided as 1-arc second spacing for the Continental U.S. and Hawaii and 2 arc-second spacing for Alaska. While elevation units are in decimeters our GIS mapping 3D software can easily import this format for viewing and analysis, while still allowing conversion to any of the supported
export formats (i.e. USGS DEM, Arc ASCII Grid, etc.) for use with other software packages.
Our policy of providing the best quality and pricing of gis mapping software and data allows us to
provide you with the following: USGS Entire National Elevation Dataset (2 DVD-ROM’s):
