[gdal-dev] Meaning of First pass in reading GeoJSON

[Rahkonen Jukka (MML)]

Hi,

What does GDAL do when it reads the whole GeoJSON file as "GeoJSON: First pass"? Could it make the total process faster if user could give the same information that is gathered with the First pass somehow directly, or is that step needed in any case?

Microsoft has an excellent GeoJSON dataset with 145 million building footprints for benchmarking at https://github.com/Microsoft/USBuildingFootprints under ODbL license (so there is at least one other user than OpenStreetMap for this license).
