Calculate slopes in GM18?

I have an elevation grid (DEM) and want to calculate the slopes for the whole map (not just view them). I keep seeing references to export in "Float/Grid format" and checking the "slopes" option...but my export options don't include either of those choices. How do I make a raster of slopes and slope directions?

Hello,
Try this:- File | Export | Export Elevation Grid Format...
- Select Export Format dialog, choose Float/Grid File
- Click OK
- Float/Grid Export Options dialog has several options related to exporting slope or slope direction values instead of elevation. Are you saying that those options are not on your Float/Grid Export Options dialog?
Cheers,
Bob
Answers
On the Float/Grid Export Options screen, choose "Export Slope Values Instead of Elevations" and "Export Percent Slope Values Rather than Degrees".
