In example of the page ST_Project the select is

SELECT ST_AsText(ST_Project('POINT(0 0)'::geography, 100000, 45));
                  st_astext
    ------------------------------------------
     POINT(0.63523102912532 0.63947233472882)
    (1 row)

But, in my enviroment this code give me an error like "Azimuth must be between -2PI and 2PI".

After a few tryings I solve with :

SELECT ST_AsText(ST_Project('POINT(0 0)'::geography, 100000, radians(45) ))

The sample in page tells the data type expected is in degrees, and the function expects radians.

May I using wrong PostGIS version?

Thanks.

BTW : My PostGIS version : 2.0

Please consult how to report documentation issues. I have the same behavior.

POSTGIS="2.0.1 r9979" GEOS="3.3.3-CAPI-1.7.4" PROJ="Rel. 4.8.0, 6 March 2012" GDAL="GDAL 1.9.2, released 2012/10/08" LIBXML="2.7.8" TOPOLOGY RASTER

    Thanks. I think it's too soon to believe its a documentation issue. Hard to believe we are wrong, but I will wait for a few days for others users to confirm. Accept your answer because I think the same. – Magno C Nov 28 '12 at 15:07

  • Hum. Looks like radians was adopted. Needs to be converted if I want to use degrees. The manual realy is incorrect. Thanks for your help. – Magno C Nov 29 '12 at 0:52
