PLEASE NOTE: These images and data
are for illustration purposes only. Do not use these documents for navigation,
legal purposes, or anything really important. They were created only to illustrate
our publications and are not accurate enough to be used for any other purposes.
These maps are in vector format. Unlike raster images, they can be rescaled without distortion. They were created in AutoCAD Map 2000 and consist of polyline segments.
To use a DXF file you need software that reads DXF files. Some commonly used DXF-capable titles are: AutoCAD, ArcInfo, CorelDraw, Paint Shop Pro, Bryce 3D, 3D Studio, and many Intergraph programs.
Click on an image to download the DXF file. You will not be able to view the files on-line. The files have been Zipped to decrease download times.

This is a vector format map.
Unlike raster images, it can be rescaled without distortion. The map were
created in ArcGIS
8.3 and consists of polyline segments. Two file formats are available: Autodesk's Drawing
Exchange Format (.DXF),
and ESRI's Shapefile (.SHP).
These are widely accepted vector data standards and are used by programs such as
ArcGIS, ArcInfo, CorelDraw, Adobe Illustrator, JASC's Paint Shop
Pro, Bryce 3D, 3D Studio Max, and many Intergraph programs.
Description: These data are produced by the State Highway Administration's Highway Mapping Team for their GRID Map base. They originally were digitized from the USGS 7.5' quadrangle maps and have been enhanced through property records research. This database does not contain the new boundary near Takoma Park between Prince George's and Montgomery counties. The data are created to be map accurate at a scale of 1:24,000. These data were created on a CAD (Computer Aided Design) type of system. They were merged into county files and converted to a GIS format by Towson State University under contract to the Maryland Office of Planning
