Slope calculation with high raster resolution

Fiona

Hi,

I have a DTM with resolution in 0.25m. I use it to calculate the slope, but results seems like elevation curves, Anyone know the reason? Resample to 1m and change the symbology didn't help.

Bests,

Fiona

I think I might be know where are the problem, the first one is after "Mosiac to new raster", the second is the original tif file. Probably the parameter in function I used were wrong.

Value from 90-0 degree.

Thank you for the suggestions, I have tried Surface Parameters, and også changed the naborhood distands to 1m/0.75m. The DTM is originally coming fra mosiac tiff, do you think it is the reason? Mosiac to new raster have been used her.

Did you try slope in the new
