03:19:00 <c_lopez> hello everybody!
03:24:58 <dkb> hello
03:26:25 <c_lopez> hi dkb how are you?
03:29:14 <dkb> ok, how has your mapnik adventures been going?
03:31:06 <c_lopez> fine, I'm learning a lot just by reading the code :)
03:34:12 <c_lopez> however, I am having some problems using mapnik_utils to read an osm xml file.
03:35:54 <dkb> the file that contains the styles?
03:40:45 <dkb> are you referring to the ogcserver?
03:45:42 <c_lopez> mmm, I'm not sure, I'm creating a Compose object, just as the script of ticket #343 does.
03:45:43 <nikq> Ticket #343: Add a resolution parameter to Map object, http://trac.mapnik.org/ticket/343
03:46:25 <c_lopez> the constructor throws many xml validation error.
03:47:26 <dkb> I'm fairly new at this stuff as well and haven't delved into details of mapnik so my ability to assist is pretty limited.
03:55:29 <c_lopez> oh, don't worry, I'll look at the code again and see if I can figure it out. thanks for your interest.

04:09:50 <waldemarq> Hello, everybody. I'm also having my own adventures with mapnik. I have a question: is it ok to fork a repository from the mapnik project and put it on github/google code?
04:19:45 *** mperry has quit (Quit: mperry)
04:21:30 <dkb> artem or springmeyer would be able to answer that but they aren't here..  not sure who else would be able to answer
04:26:36 <waldemarq> oh, ok. thanks for answering though :)

09:27:22 *** BillK (~BillK@124-148-220-8.dyn.iinet.net.au) has joined #mapnik
09:31:27 <BillK> is it possible to export from a mapnik postgres db to an osm file?
09:44:04 <c_lopez> I read that Osmosis can do that sort of things: http://wiki.openstreetmap.org/wiki/Osmosis. In the 'Example Usage' section: 'Export a planet file from a local PostgreSQL rails port database'.
09:54:16 <BillK> c_lopez: osmosis wont work on a mapnik type db - the standard osm database uses rails  - looks like I am going to need to run two parralel dabases :(
10:00:43 <c_lopez> sorry, I didn't know that.

14:56:50 <steven__> No. I need to create one?
14:57:26 <rweait> steven__: I think the login is required to add a ticket.  Spam problems otherwise.  :-(
14:57:40 <steven__> OK

15:52:31 <hesco> I have a mapnik script building a county map from TIGER data.  I get the 'painter's algoryth'.  What I don't understand is what these various shape files actually represent and what order they ought to be sorted in.  TIGER offers me: arealm, areawater, bg00, cousub00, cousub, edges, pointlm, tabblock00, tabblock, tz00, tract00.  Can someone please advise where these layers are documented and / or suggest an appropriate order to render them
16:01:21 <hesco> Here is my sample code: http://pastebin.com/dgqXi4JJ

16:48:31 <cgs_bob> hesco: you might get some clues with the tiger geocoder.  you can get it by doing this:  git clone http://www.snowman.net/git/tiger_geocoder/
