in3Utils.geoTrans.remeshDEM

remeshDEM(demFile, cfgSim)[source]

change DEM cell size by reprojecting on a new grid - first check if remeshed DEM available

the new DEM is as big or smaller as the original DEM and saved to Inputs/DEMremshed as remeshedDEMcellSize

Interpolation is based on griddata with a cubic method. Here would be the place to change the order of the interpolation or to switch to another interpolation method.

Parameters

  • demFile (str or pathlib path) – path to DEM in Inputs/

  • cfgSim (configParser) – meshCellSizeThreshold : threshold under which no remeshing is done meshCellSize : desired cell size

Returns

pathDem – path of DEM with desired cell size relative to Inputs/

Return type

str
