10. After projecting all of the coverages into their proper zone, grid lines must be made for
the new UTM zone. Go back to the data workspace (W ../data). First, make a template of just the
new UTM zone (e.g., for Kansas River, it was zone 15) using the existing two UTM zone tem-
plates:

Arcedit: CREATE utmtemp4 utmtemp3

Arcedit: GET utmtemp3

11. There are five sets of grids that need to be generated. Three of them will be the new
GRID50, GRID10 and GRID5 coverages. The fourth will be the new 100K grid (BIG) and the last
will make up the 20K section boxes (e.g., C2BOXES and E2BOXES for the Kansas River). First, go
back to the new UTM zone workspace (let's stick to zone 15 for the example: W ../zone15). Then
type DESCRIBE utmtemp15. Find the "xmin," "xmax," and "ymax" values for the coverage. Jot
these numbers down someplace and keep them handy.
12. When generating the fishnets, set the x-values of the origin to be the "xmin" value, trun-
cated by the closest multiple of the unit size of the grid. Example: If the xmin value is 166338, then,
for the 100K grid (BIG), the origin values would be 100000,0 and 100000,1; for GRID50, 150000,0
and 150000,1; etc. To generate a 100K grid, with boundary coordinates (166338,0),
(866237,9993455):
