[postgis-users] Patch for casting geometry to geography

[Marshall, Steve]

I get an error when I try to post to the URL below:
TICKET_CREATE privileges are required to perform this operation

Do I need a particular account to post to OSGEO?  Can someone either
explain to me how to get the proper credential, or post my patch as a
bug ticket to OSGEO?

Thanks,
Steve

Steve,

It would help if you posted this issue as a bug ticket and then attach
the
patch to it.  
http://trac.osgeo.org/postgis/newticket

That way it will get on our list on items.



Since it doesn't require an external function addition, I think it can
be
slated for PostGIS 1.5.3

Thanks,

Related to an earlier post by Radu Ilie, I have a patch for casting from
geometry to geography that solves his problem.  In particular, it will
transform coordinates into the desired range for geography objects (-90
to
90 lat, -180 to 180 lon).  The previous version detected this problem,
but
simply issued an error if it occurred.

The attached files add one new external function to the the postgis
library
(lwgeom_force_geodetic) and uses it in the function that casts geometry
objects to geography objects (Datum geography_in).  The logic is a very
simple clone of the lwgeom_check_geodetic function, except it fixes any
descrepancies it finds.

I hope this could be included in a future PostGIS release.  If
necessary, I
can post this to a different list.

Steve Marshall
