Hi, Rigved, With PDFs exported from autocad, Rajesvari Parasa had worked out a method shared here: https://github.com/draftmpd41/layers_draft_delhi_master_plan_2041
Example ogr2ogr command: ogr2ogr -f "GEOJSON" Boundaries_DDA_ZONE_Boundary_polyline.geojson draftplan.pdf Layers_Boundries_DDA_ZONE_Boundary_polyline -s_srs EPSG:32643 -t_srs EPSG:4326 --config OGR_PDF_READ_NON_STRUCTURED YES It seems ogr2ogr supports dwg format as well: https://gdal.org/drivers/vector/dwg.html But I guess some R&D would be needed to get the exact command. I'm reckoning the ogr2ogr command wraps in some of the conversions details in Nishad's thread. when I import them in QGIS they show up at 0,0 lat long If the shapes once imported into QGIS have retained their geometry, then we're in luck. Rajesvari was facing the same issue, except in her case the shapes were many times bigger than the world map. We then used this site: http://projfinder.com/ (not ssl so bear with bsnl popups and reload) Enter a lat-long value from your shape, then move the map to the actual location where that point should be. You'll get a list of possible CRS projections. Try them out by varying the *-s_src* argument in the ogr2ogr command above. -- Cheers, Nikhil VJ https://nikhilvj.co.in On Wed, Mar 2, 2022 at 10:22 AM Nishadh K A <nishad...@gmail.com> wrote: > Check this thread, > https://groups.google.com/g/datameet/c/cnPMEQ7Cr6Q/m/cA3vJlrCAAAJ > The steps followed are *Autocad DXF->Geojson->Geometry > conversion(line/polygon on need basis)->geo referencing the geometry* > > -- > Datameet is a community of Data Science enthusiasts in India.
