SDTS: Spatial Data Transfer SystemSpatial Data Transfer System
All Federal agencies produce data in this format.
ArcInfo supports this standard: SDTSIMPORT
Several processes must be run before you can run SDTSIMPORT.
winzip Tar SDTSIMPORT
SDTS2COV.aml SDTS2ARC.aml
AutoCAD format (DXF)
Pretty straight forward BUT:
If the AutoCAD file is in color and layersthere may be some other files in the info directory that need to be joined. (X_code, A_code)
Arc:\DXFINFO = inventories the layers in the DXF file
Arc:\DXFARC = opens a dialogue to convert the layers
