I am preprocessing a DEM (cartoset v1) using arcHydro for basin property extraction. The issue is while processing catchment grid with spatial ref. GCS_WCS_1984, it is working fine. But when using projected re. ie. WGS1984 UTM ZONE 44N , I an getting
Sorting Attributes... Dissolving... ERROR 999999: Error executing function. Invalid Topology [Maximum tolerance exceeded.] Failed to execute (Dissolve). Failed at Wed Aug 24 06:17:33 2016 (Elapsed Time: 2.05 seconds) Error HRESULT E_FAIL has been returned from a call to a COM component. Failed to execute (CatchmentPolyProcessing).
I am using arcgis 10.3. I have to use WGS1984 UTM ZONE 44N because we cannot calculate slope without projection system.
my environment setting are attached.
