About the Data
The DWG files are copies of USGS 1:24000 DLGs projected into the appropriate
State Plane Coordinate Zones (NAD83) by FREAC under contract with The
Division of State Lands and other agencies. The DWG files are intended for Auto-Cad users (the attributes are stripped).
| Projection: | | State Plane |
| Datum: | | NAD83 |
| Units: | | Feet |
| File Type: | | DWG (AutoCad) |
Some DLGs have been revised since their original creation. For more information on this topic, see the
paper explaining DLG Revisions.

Determining the File Name
You will need to know the DEP quad number. Use the
Quad Name Locator to find this information.
The file names are comprised of the DEP quad number plus the first letter of the State Plane Zone they are projected into (borderline quads
may exist in more than one zone).
Downloading Instructions
These files are small enough to download easily, but if you experience difficulty, using
FTP is recommended.
These files are available on CD for $25 each. (A CD holds
several quads.)
Special Software Needed
Intended for use with AutoCad
