Hi Doug,

As Desktop-Client for PostGIS - besides QGIS and UDIG - you can try:

- OpenJUMP(http://www.openjump.org) with the SISDB-Plugin (for improved PostGIS-connections), thematic mapping (without the natural breaks routine) - Kosmo (http://saig.es/en/index.php) , thematic mapping (without the natural breaks routine) - gvSIG (http://www.gvsig.gva.es), thematic mapping with support of natural breaks (the support for postgis-geometry-types is constrained => editing postgis-tables can be annoying) - Spatial Commander (http://www.gdv.com/down/scommander.php) NON-OSS, !only in GERMAN!, thematic mapping with support of natural breaks (editing with postgis-tables can also be difficult) - Thuban (http://thuban.intevation.org), thematic mapping without natural breaks, but other possibilities

regards,
Johannes

Hi Jim,

QGIS (which is what I assume you mean by "Quantum") allows you to create
thematic maps using PostGIS layers. Go to the properties of a layer and
muck with the legend type. Alternatively, you can load PostGIS layers
into uDig (http://udig.refractions.net), and alter the style of a layer.

I am new to PostGIS, and want a good Windows desktop mapping tool to
view and thematically map boundary data from my PostGIS database.  I
have Quantum, which is a nice viewer, but it doesn’t seem to do
thematic mapping.  I am a heavy MapInfo and Maptitude user, but they
don’t read PostGIS spatial boundaries.  I wish they would.

Is there a free/inexpensive tool to view and do some nice thematics?
I would also like to have the “natural break” routine, which I use by
default since it’s the beast way to break up the categories.

I have been doing all my database work in SQL Server and then linking
from MapInfo and linking with equivalent boundary files (census block
groups and zip codes for all USA).  That’s for the birds when I’m
running routines in SQL Server and want to view the results
graphically on an interactive basis.  It’s very clumsy.  So
PostgeSQL/PostGIS is a much better solution but I haven’t found a good
way to view the results spatially.

Thanks…..

Doug
