GeoDataScape LLC offers three new raster base data image products to the GIS professional, Cartographer, or graphic artist. Each is georeferenced and based on USGS standard DEM and raster graphics data. All of our rasters are GIS or SDE ready and will follow the USGS Quad ID scheme for easy identification.
3DRGs are a 3D hill-shaded Digital Raster Graphics (DRGs), created by fusing the USGS DRG with a shaded relief Digital Elevation Model (DEM). Each image is GIS or SDE ready with collars removed and referenced to your state agencies most common projection. Our 3DRGs have an optimized palette and color depth allowing for stunning graphics with smaller storage requirements. These beautiful topographic maps are available in 1:24,000, 1:100,000 and 1:250,000 scale.
3DOQs are a 3D hill-shaded Digital Orthophoto Quadrangle (DOQ), created by fusing the DOQ with a shaded relief DEM. Each raster is mosaic ready and referenced to your state agencies most common projection. These orthorectified images are available in 1:24,000, 1:100,000 and 1:250,000 scale.
Shaded Relief Quadrangles (SRQs) are preprocessed images of shaded relief Digital Elevation Models (DEMs). The SRQs are GIS or SDE ready and will follow the USGS Quad ID scheme for easy identification. Each raster comes referenced to your state agencies most common projection. These images are available in 1:24,000 (based on USGS 10m DEMs), 1:100,000 (based on National Elevation Dataset), and 1:250,000 (based on National Elevation Dataset) scale. |
