I am trying to reclassify a profile curvature raster generated by the
Curvature tool available in ArcGIS into three classes following the tool help where it is reported that;
...a negative value indicates the surface is upwardly convex at that cell. A positive profile indicates the surface is upwardly concave at that cell. A value of 0 indicates the surface is flat.
My Curvature raster' values range between -4.726 to 0.543. By supplying class breaks (-4.726, 0, 0.543) in the
Reclassify tool yield spurious results where pixels having values == 0, as separately identified by raster calculator, are more in numbers (pixel count) than it should be!
What are optimal class break values to get accurate reclassified Curvature raster?
