[postgis-users] Using transform with proj4 string.

[John Cole]

Hey, I was just looking at this...

 

There is a transform_geometry(geometry, text, text, integer) function, but I
can't find any documentation on this.  I'd like to be able to be able to
transform into a custom projection for processing (in my case using
simplify) and then back to my srid based projection.

 

Could someone provide a little insite into transform_geometry?

 

Thanks,

 

John

Is there any way to use TRANSFORM with proj4 strings.  Something like;
transform(geom,'+proj=merc +lat_0=0.0 +long_0=0.0 +x_0=0 +y_0=0 +datum=WGS84
+units=m +no_defs')

Thanks,
