A lot og my shapefiles with a .prj file (EPSG:32188) are imported as EPSG:2950



Doesn't cause any real problem in QGIS for mapping, but when exported to PostGIS, it causes operations on mixed geometry with my others EPSG:32188 layers...

#1 Updated by Giovanni Manghi over 8 years ago

  • Category set to Projection Support
  • Subject changed from When opening shapefile, the wrong SR is imported to EPSG:32188 is recognized as EPSG:2950

note, proj4 strings of this two CRS are identical:

+proj=tmerc +lat_0=0 +lon_0=-73.5 +k=0.9999 +x_0=304800 +y_0=0 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs

+proj=tmerc +lat_0=0 +lon_0=-73.5 +k=0.9999 +x_0=304800 +y_0=0 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs

#2 Updated by Giovanni Manghi almost 7 years ago

  • Easy fix? set to No
  • Regression? set to No

#3 Updated by Jürgen Fischer almost 7 years ago

  • Status changed from Open to Closed
  • Description updated (diff)
  • Resolution set to wontfix

The content of the .prj file doesn't carry the EPSG - hence the CRS is looked up with the proj.4 definition, which is not unique.
Use Processing/Define current projection to add a .qpj file to the layer.
