unrecognized EPSG code #1

Open spaceof7 opened 8 years ago

I tried running the BreachDepressions tool on a dem that is in CRS EPSG:2285 (Washington StatePlane North, US feet). I get the following output:

`Reading DEM data... Could not find tag 2062 Filling DEM: 100% Saving DEM data... panic: Unrecognized EPSG code.

If I reproject into UTM 10N (EPSG:26910) The tool runs fine. I also tried reprojecting back in to 2285 to see if there was some error in the original file but that gave me the same error again.

I get the same error running the BreachDepressions tool with USA_Contiguous_Albers_Equal_Area_Conic_USGS_version (7480). Also tried North_America_Lambert_Conformal_Conic and North_America_Albers_Equal_Area_Conic receiving the same error. Also works for me with UTM.

It seems to run through the entire process and crashes on "Saving DEM data...".

thank you!

I am getting the same error as the users above by executing "run BreachDepressions" on a DEM with a custom (WRF-Hydro) projected coordinate system. The error message is:

panic: Unrecognized EPSG code.

This occurs during the "Saving DEM data..." step, after all processing is completed. I wonder if these handy tools can be updated to ignore unrecognized EPSG codes? From what I can tell, the go-spatial Breach Depressions tool may be the only available tool allowing the Lindsay (2016) unconstrained breaching (without subsequent pit filling).

Thanks for any guidance you can provide!
