How can I do this command (source):

ogrinfo -q -sql "SELECT SUM(OGR_GEOM_AREA) AS TOTAL_AREA FROM way" way.geojson

with Python ogr?

from osgeo import ogr

  • Are you aware that the result will not make much sense because GeoJSON is using long/lat degrees as units and square degree as an area unit is useless?

  • The problem is in the projection, not in the format.

  • Don't understand me wrong, what you want to do is OK and you can do it with Python and executeSQL like in gis.stackexchange.com/questions/114112/…. The result just is not useful for you. You must learn a bit about different projections and transform data into some suitable coordinate system for area measurements.
