HOW TO
The SDTSEXPORT command requires that a polygon coverage be provided which represents the bounding extent of the points being exported. This article provides the sequence of steps necessary to create the polygon coverage.

Note:
Topological Vector Profile (TVP) is a subset of the Spatial Data Transfer Standard (SDTS), and TVP only allows the following external reference systems and units. If the data is in any other coordinate system than those listed below, the coverage must be projected before running SDTSEXPORT.
GEO - Lat/Long GEOGRAPHIC /* Geographic (latitude and longitude)
SPCS - meters STATEPLANE /* State Plane Coordinate Systems
UTM - meters UTM /* Universal Transverse Mercator
UPS - meters UPSTEREOGRAPHIC /* Universal Polar Stereographic
