[gdal-dev] Command line text input (a WKT) to OGR e.g. to transform a coordinate using ogr2ogr?

Hi,

Gdaltransform should be a rather close hit
https://gdal.org/programs/gdaltransform.html#gdaltransform

Usage example with your point

gdaltransform -s_srs epsg:4326 -t_srs epsg:2056
Enter X Y [Z [T]] values separated by space, and press Return.
10.1989 45.9461
2814015.23490644 1092044.84521026 0

But of course you can do the same with ogrinfo and SQLite SQL dialect. Here
done on Windows and with a WKT written into the command. Notice that for
ogrinfo some vector source must exist even the command does not read any
data from there. 

ogrinfo -dialect sqlite -sql "select
st_x(st_transform(setsrid(st_geomfromtext('POINT(10.1989
45.9461)'),4326),2056))||','||st_y(st_transform(setsrid(st_geomfromtext('POINT(10.1989
45.9461)'),4326),2056)) as xy" foo.shp|find "xy"
xy: String (0.0)
  xy (String) = 2814015.23490644,1092044.84521027
