Hi Nikhil, This is super work!! It can really speed up processes for capturing Citizen feedbacks on Master Plan. Always needs another specialised agency when Planning Authorities need to publish draft master plans for citizen inputs. My learning - generating geojson/shp files using ogr2ogr tool. I was not aware of it.
