[gdal-dev] ogr2ogr VSI support for JSON input?

[Ryan Clark]

I'm curious if the GeoJSON driver does not support the VSI API completely?

This works (stream WFS > GeoJSON):

    curl "http://server.com/wfs?request=GetFeature..." | ogr2ogr -f "GeoJSON" /vsistdout/ /vsistdin/

but this doesn't (stream GeoJSON > KML):

    cat ~/my-geojson.json | ogr2ogr -f "KML" /vsistdout/ /vsistdin/

... that is, I can't seem to stream GeoJSON as an input to ogr2ogr. Is that a known issue or am I doing something wrong? The documentation<http://www.gdal.org/ogr/drv_geojson.html> states that I should be able to do this, but I'm receiving an error:

$ cat my-geojson.json | ogr2ogr -f "KML" /vsistdout/ /vsistdin/
ERROR 1: GeoJSON parsing error: unexpected end of data (at offset 6000)
ERROR 4: Failed to read GeoJSON data
FAILURE:
Unable to open datasource `/vsistdin/' with the following drivers.
...


I'm working with GDAL 1.10.0.

Thank you!
Ryan
