The following is a listing of how to do this using arc info. All commands for Arc Info will be printed in bold here. Wherever the word "cover" appears, enter the name of the coverage in current working directory.
A list of all valid coverages in your current directory will be returned:
Arc: lc Workspace: /A/BBQ/U5/LOCAL/ETC/HTTPD/NCGIA/EDUCATION/CURRICULA/CCTP/UNITS/UNIT33 Available Coverages ------------------- BUFFER BUFFER2 BUFFER3 BUFFER4 BUFFEROUT
This will look something like this:
Arc: describe buffer

COVERAGE BOUNDARY
Xmin = 1.415 Xmax = 6.398
Ymin = 1.156 Ymax = 4.392
STATUS
The coverage has not been Edited since the last BUILD or CLEAN.
NO COORDINATE SYSTEM DEFINED
Notice that the Coverage Boundary is described. If the units are not expected, for example they are too big or too small, this is a cue that there is a problem. If a coordinate system has been defined, it should be completely described. Further resources for resolving this problem can be found in Unit 10.
