Import doesn't work on mapshaper.org for ESRI File Geodb format #514

Closed antonrinas closed 2 years ago

antonrinas commented 2 years ago

I'm trying to import this file: https://www.hudexchange.info/resources/documents/CoC_GIS_National_Boundary_2021.zip here https://mapshaper.org/ But nothing happens. I tried to drop the file and by using the "Select" button. I'm using the last Chrome.

Zip file contain ESRI File Geodb format which is not recognized by mapsahper.

If you need it as shp, download it https://www.hudexchange.info/resources/documents/CoC_GIS_National_Boundary_2021.zip uncompress. Rename directory CoC_GIS_National_Boundary_2021 to CoC_GIS_National_Boundary_2021.gdb and then do

ogr2ogr output.shp CoC_GIS_National_Boundary_2021.gdb FY21_CoC_National_Bnd -lco ENCODING=UTF-8

PS: I consider you know how to install and use GDAL command line utility ogr2ogr

@ThomasG77 Thank you! It works for me! For me an algorithm was next (maybe it'll be useful for somebody):
