Digital Raster Graphics (DRGs)
While itself a generic term, DRG typically refers to scanned versions of printed maps. Them most common are 1:24,000 (7.5') USGS topographic maps.
- 7.5' DRGs for California are available within ADL
- Cal-Atlas has trimmed and untrimmed 7.5', 30' and 1 degree DRGs. The files were originally created by the Teale Data Center (now the California Technology Agency).
- Technical information about the Teale DRG projection
- ESRI .prj file for use with Teale DRGs
- Digital Raster Graphics
- Geographic Data Library
- Online Sources for Free DRGs
- Teale DRG index
