I have a DEM and I want to analyse it using the
Locate Outliers tool in ArcMap; however the tool only supports Terrain or LAS input files.
How to convert the raster DEM to a format that Locate Outliers can read?
The Locate Outliers tool can take 3 types of inputs: TIN, Terrain dataset and LAS dataset. As stated by @GBG, TINs are simpler to output from a DEM.
To accomplish such task, first convert your raster data to vector. Some options are:
Then, using any of previous outputs to create a TIN.
Another option would be to directly smooth the DEM, instead of converting it to other type of data.
