I want to analyse a surface based on the height. So i want arcmap to show me all of the areas over 500m and all the areas under 500m. I already have the dgm, but i dont know which tool i have to use.
Thanks for the help.
raster calculator or con
Building expressions in Raster Calculator—Help | ArcGIS Desktop
Conditional evaluation with Con—Help | ArcGIS Desktop
you can build in two conditions using con
but yours is simple
gt_500 = your_raster > 500
will result in a binary raster, 0 and 1, showing the areas <= 500 (the 0's) and those areas > 500 (the 1's)
If you want to keep the elevations, there are a variety of ways
gt_500_vals = (your_raster > 500) * your_raster
or using the con statement
OutRas = Con((your_raster > 500), your_raster, 0) # or whatever
Thanks a lot, Dan!
