I am trying to import a shp archive (dbf, shp, shx) into Immerse, without success:
import_geo_table failed: invalid geometry: duplicate vertex found Feature: 10
Now, the message is pretty clear, but how could I identify and solve this duplicate vertex problem ?
Same problem for the data in geojson format from:
Some additional detail:
From the above link keeping only the first polygon, the import is fine ( meaning no error "duplicate vertex found appears).
But the data aren’t fine:
NOME_PRO mapd_geo_coords mapd_geo_indices mapd_geo_linedrawinfo mapd_geo_polydrawinfo
Vercelli <Error> <Error> <Error> <Error>
How to import correctly the geojson file?
