1. dem times two:
- Spatial Analyst > Map Algebra > Raster Calculator
- On the first input field of second row, type
"dem" + "dem"
2. Neighborhood
Replaces all values with neighborhood's (defined by rectangle/circle/...) value (mean, min, ...)
- Spatial Analyst > Neighborhood > Block Statistics
3. Query
- Spatial Analyst > Map Algebra > Raster Calculator
- Use expression:
"dem" > 2500"
- Cells that evaluate to true, produces
1, else 0
4. Distance
Euclidean Distance: Straight line distance. May not be much sensible within today's context.
- Spatial Analyst > Distance > Euclidean Distance
