[GIS] How to convert data from GML to GeoJSON using ogr2ogr

geojsongmlogr2ogr

How should I convert GML to geojson data using ogr2ogr.
I used :

ogr2ogr -f "GeoJSON" bd.geojson bd.gml

But in this case I have only part of my data , not all.
I tried add -append , but it didn't work properly.

It's hard to say for sure what the issue is based on your question, but you could try to use the -nlt flag (from documentation http://www.gdal.org/ogr2ogr.html). This will (explicitly) specify the output geometry type. Since you have mixed geometry you might try the command ogr2ogr -f "GeoJSON" -nlt "GEOMETRYCOLLECTION" bd.geojson bd.gml
