I made a source release of PCL yesterday, and it is available from
From now on, all releases will be from that URL. 0.9.0 was the last
sourceforge release. Changes in this version:
0.9.1: 19 November 2005
- Fixed typo in PostGIS LineString type, patch by jdenisgiguere
- Auto label angle is now the default for text symbolizers (issue 83).
- Default TextSymbolizers now should exhibit the "best" placement
using collision avoidance and automatic label rotation. Distance
duplicate labels, and padding between labels can also now be
- New cartography.referencing module can be installed and used
of the rest of PCL. It depends *only* on the PROJ.4 library
It's the last of these that inspired me to cut a release. If you've
got PROJ.4 on your system, you can build, install, and use
cartography.referencing independently of the rest of the Python
Cartographic Library. This work is a by-product of my recent work on
Nuxeo's CPSGeo product.
Notes about the development and testing of the module at
and usage documentation at
Why cartography.referencing? I've been itching for something between
OGR's osr.py (too complex) and PyProjection (forward/inverse only).
cartography.referencing uses pj_transform() from PROJ.4 and so is
roughly equivalent to the cs2cs utility function. For best
performance, transform coordinates en masse rather than one at a time.
