What are DATASHEETS:
A Datasheet is sometimes referred to as DSDATA
It is an ASCII text file which contains data
for a survey control station maintained by NGS.
Datasheets for horizontal control stations
show precise LATITUDE and LONGITUDE
Datasheets for vertical control stations (a.k.a. Bench Marks)
show precise Orthometric Heights (Elevations)
Other data includes...
Geoid Ht, State Plane Coordinates, UTMs, and more
Description of how to reach the mark
and recovery information is also provided.

Input is provided for retrieving by...
PID, Point Radius, Min/Max, StationName, Quad
ProjectID, County, LoadDate, or Interactive Map

Supporting Programs:
DSWIN
(06/09/04)
- Used on the PC for searching a file of datasheets,
and extracting the data into a single line delimited format.
DSFILES
(06/09/04)
- Used on the PC for joining or splitting files of datasheets.
DSUPDATE
(09/17/03)
- Used on the PC for updating a file of datasheets.
Convert Datasheets to Delimited Records:
You can convert Standard Datasheets to delimited records
by loading them into PC program DSWIN or DSFILES
then saving them as DSSELECT format.

into ArcView ShapeFiles.
