DRGs are available for immediate download in any standard projection (State Plane, UTM, Lat/Long - 27 or 83). Both collared and collarless DRGs are in GeoTIFF format, a TFW file is included with the .TIF file. File sizes are approximately five megabytes per quad (Zipped). DRGs are available by the quad or custom area anywhere in the continent US.

Seamless custom area DRGs also available for immediate download in any standard projection.

MapMart updates DRGs on a monthly basis thus assuring you of always receiving the latest available DRG.
   Seamless Digital Raster Graphics Description Pricing View Samples
 
Seamless DRGs are available for immediate download in any standard projection (State Plane, UTM, Lat/Long - 27 or 83).

Seamless data are data where the boundaries are defined by the user. Traditionally boundaries have been pre-defined by 7.5', 30' x 60' or 2° x 1° areas of Latitude and Longitude. Now MapMart allows user to define custom data boundaries by drawing a rectangle for downloading DRGs.

***** Available for immediate download. *****
These maps are perfect to investigate terrain of a region. Heights are given in feet. All airports even with the right heading of the runway and much other flight relevant information are marked. As is it made for Pilots flying relatively quick over terrain, the built up area information as well as the road network information is quite basic on these maps.

Topographic Base Map: Hydrography, depth contours, major and minor towns, railways, main roads, power transmission lines, selected landmark features, contours and spot heights in feet, layer tints, shaded relief, general vegetation and distinctive vegetation.

Aeronautical layer: Aerodromes, radio facilities, aeronautical and marine lights, obstructions, isogonals, maximum terrain elevations and maximum elevation figures.

Mapmart has topographic map coverage of over 152 countries. Our maps are available in a variety of digital formats, scales, resolution, and projections and are fully georeferenced and formatted for all GIS/GPS applications.

Geo-referencing

Not only can Mapmart supply you with digital topographic, maps we can supply you with all of your geo-referencing needs. To make our products more user-friendly we can process the map to a projection and datum of your specification.

Geo-referenceing is established by correlating the relationship between an image (row, column) coordinate system and a map (x,y) coordinate system, yielding a digital topographic map opening in GIS software in precise geographic location.

Quality Control

Each topographic map goes through a series of quality control steps to ensure you are provided with the highest quality GIS data for each project. Three steps we use to achieve the highest quality are:

  • The raw topographic map is checked against the paper topographic map to verify an accurate digital representation.
  • The processed topographic map is carefully inspected to assure that the topographic map is properly geo-referenced.
  • The four edges of the processed topographic map are compared to adjoining topographic maps to confirm proper alignment.
Map Scales

Depending upon the printing source of the topographic maps, there are a variety of scales available for any given area of the earth. The following are some of the typical scales for both domestic and international topographic maps.
