[postgis-users] Windows Installers for PostGIS 2.0.0 including 64-bit
We have all the installers up on PostGIS site, but before we put it on stack builder (or rather give final okay to push to all deployment servers), we'd appreciate if some others test them or let us know your experiences whether successful or not. We've had some people test and some have run into issues. Some of the issues we have fixed, but we can't test all the permutations of how people have their postgresql configured to be sure it works for all and since we are not running into issues on the servers we've tested on, we can't be sure if these are isolated incidents or not. Case in point -- this one: http://trac.osgeo.org/postgis/ticket/1781 http://www.postgis.org/download/windows/#postgis-installers NOTE: PostGIS 2.0.0 is the first ever version to support PostgreSQL 64-bit (both 9.0 and 9.1) on windows. We'd again like to extend a big thank-you for our windows 64-bit campaign sponsors for making this a reality.

Re: [postgis-users] Returning contiguous linestrings
Hi Nicolas I have, lets say, eight rows each containing a linestring, that, when put together forms a closed shape or polygon. I can fairly easily detect one of the linestrings in this polygon. Since each linestring has a endpoint at (or near) the startpoint of the next linestring in the polygon, I am wondering if there is a method of detecting the other linestrings, that forms a closed polygon, from that one contact. From this I would compare the shape to known shapes to identify it. I have some ideas on how to possibly do this, but, I would rather not invent a function if a suitable one already exists.

But I guess it would "work" if you mark it as such. Only you won't have the update index on updated TopoGeometry semantic. An interesting research topic could be about how to notify TopoGeometry objects about changes occurred in the underlying table. We should have all information we need to find the TopoGeometry objects (so we could do a faked UPDATE or something like that to force re-indexing). > I will keep trying to study and to help you if I can.

Great, looking forward for more contributions :) Beside, since you're looking at ST_Intersection, it may be worth adding a testcase for it as I'm pretty sure it has some unwanted side effects like throwing an exception when passed TopoGeometry objects from different topologies... --strk; ,--o-. | __/ |Delivering high quality PostGIS 2.0 ! | / 2.0 |http://strk.keybit.net - http://vizzuality.com `-o--' ___ postgis-users mailing list postgis-users@postgis.refractions.net http://postgis.refractions.net/mailman/listinfo/postgis-users

Thanks Mike I could solve it with your help: I've checked my postgis config.log and found this: /usr/bin/ld: warning: libpq.so.5, needed by /usr/local/lib/libgdal.so, not found (try using -rpath or -rpath-link) I had installed postgres 9.1.3 from sources in /usr/local/pgsql and the symlinks libpq.so.* are in /usr/local/pgsql/lib So I added that directory to ld.so.conf, run ldconfig and the ./configure of postgis passed.
