Hi Even,

I'm implementing Proj.4 in GMT via GDAL and now, in the the testing stage,  
I'm using data from


but to my surprise lots of projections are not implemented in GDAL. For  

gdaltransform -s_srs EPSG:4326 -t_srs +proj=airy +ellps=WGS84 +units=m
ERROR 1: Translating source or target SRS failed:


gdaltransform -s_srs EPSG:4326 -t_srs +proj=bonne
ERROR 6: Failed to initialize PROJ.4 with `+proj=bonne +lon_0=0 +lat_1=0  
+x_0=0 +y_0=0 +ellps=WGS84 +units=m +no_defs'.

Is there a place where I can find the list of available proj.4 transforms?

And also found some that do no agree between GDAL and proj. For example

echo 4.897 52.371 | proj +proj=vandg +ellps=WGS84 +units=m
489005.93       6431581.02

gdaltransform -s_srs EPSG:4326 -t_srs "+proj=vandg +ellps=WGS84 +units=m"
4.897 52.371
488459.293282675 6424391.46347316 0
