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.
- Starting from your operating system prompt type arc
- When ARC Info starts, type: display 9999,display 9999 2, display 9999 3, or display 9999 4. These will return increasingly larger viewing windows.
- Next type ap or arcplot
This will initialize arcplot, the visualization module of arcinfo.
- Set the viewing extent to the extent of the data you will be viewing by typing mapextent cover, or mape cover
- If you are viewing points type points cover
- If you are viewing arcs type arcs cover
- If you are viewing polygons, type polys cover
- Look at all of the coverages that you are using on the same screen,
set to the same mapextent. If a coverage does not appear, and there was
no error message in the command window, a projection problem exists.
- Type mapinfo. This will send a report to your command window
listing out positional information for your current viewing window.
