CD/MAPS by Sylvan Ascent, Inc.
Listed in NASA Earthdata CMR
Description
The Web site for CD/MAPS is: "sylvanmaps.com/" The Web site to order online maps is: "topodepot.com" Sylvan Ascent Inc. has made available digitital maps derived from: US Census Bureau's pioneering TIGER-Line data USGS 3 Arc Second Digital Elevation Model (DEM) data USGS Digital Line Graph (DLG) data USGS Geographical Names Information System (GNIS) data All data has been converted into AutoCAD DWG format for easy use in AutoCAD, AutoCAD Map or ArcCAD software.
Each map corresponds to a USGS 7 minute map, with the USGS naming convention (ie. 34106-E1) used to facilitate locating the map you need. Road names have been added, and conversion has been made to state-plane coordinate systems. Maps are available for all 50 states, and include layers for legends, roadways, hydrologic data, contours in either 50 or 100 ft. intervals, landmarks, etc.

Layers for the Public Land Survey System are available for some states at additional cost. Each CD volume also includes a USGS 1:2 Million DLG map denoting boundaries, highways, water features, US government boundaries, and railroads. Maps are distributed with an entire state on a CD-ROM with the following exceptions: California is two CDs, north & south of 37 Texas is two CDs, east & west of 99 Montana is two CDs, north & south of 47 Vermont and New Hampshire are together in a single CD Massachusetts, Connecticut and Rhode Island are together in a single CD New Jersey, Delaware, Maryland and the District of Columbia are together on one CD.
Utilities are included with each CD allow for: Map cross reference, simplified downloading and adjacent quadrangles Conversion from single-line to double-line roads with intersection clean-up Coordinate system conversion to latitude-longitude, UTM, Albers and NAD 83 Contour elevation labeling Polyline vertices connect across map boundaries DXF output
