00:03:26 razla: When comparing PostGIS to Oracle spatial and MySQL with spatial extention, what are the main factors or areas you'd investigate/compare?
00:50:00 razla: I'm searching for like a hypothesis type of statement on making comparison analysis in aspects of spatial dbms, any suggestions?
01:14:13 CIA-34: mloskot * r3946 /spike/wktraster/scripts/ ( Makefile.rt Makefile.rt.sample ): [wktraster] Renamed scripts/Makefile.rt to scripts.Makefile.rt.sample.
02:58:14 mloskot: holy cow, how could I forget to calculate georeferencing for tiles
02:58:37 mloskot: @seen pracine
02:58:37 sigq: mloskot: pracine was last seen in #postgis 3 weeks, 2 days, 17 hours, 56 minutes, and 23 seconds ago: <pracine> ok
02:58:49 strk: you may try to guess, sinc eyou're doing "regular blocking" : )
02:59:05 strk: should take far less then 40 minutes for an SQL call : )
02:59:21 : * strk just read mloskot's blog posts about crunching...
03:00:03 mloskot: strk: re 40 min, probably it would
03:00:52 : * mloskot - the god of being smart-ass - has put shame on himself
03:02:11 strk: it'd take less then 12 minutes
03:02:35 mloskot: yes Sir : )
03:49:39 CIA-34: mloskot * r3947 /spike/wktraster/scripts/gdal2wktraster.py: [wktraster] Added missing calculation of georeferencing for tiles. Previously, each tile was generated using the same geo-transformation parameters ( upper-left corner ), quite a bug.
06:11:27 sanova: hi all
06:13:08 sanova: i'm trying to find a way to connect a db in postgre to a shape published in web throught a web-gis application. is possible to do that? anyone can help me?
06:15:45 sanova: i have done a join between dbf and table in postgre through mapfile ( so mapserver ) but it doesn't work fine
06:16:12 sanova: is there a solution ?
06:17:35 strk: have asked on #mapserver ?
06:20:03 mloskot: sanova: yes, it is possible to do that and yes there is a solution.
06:20:18 CIA-34: mloskot * r3948 /spike/wktraster/scripts/window.py: [wktraster] Added scripts/window.py - a simple replacement for pencil-and-paper to calculate window corners of given raster using georeferencing information.
06:20:24 mloskot: ls -l
06:20:46 sanova: strk, yes i asked on mapserver
06:22:07 sanova: mloskot, oh great news : )
06:22:07 ue: sanova, write a scriptsthat downloads that file & shp2pgsql to your db, ~every 1 day for example
06:23:30 mloskot: sanova: or expose your file using a service that can dump geojson, then use ogr2ogr to dump geojson to shapefile, then use shp2pgsql ( or again ogr2ogr ) to dump it to postgis
06:24:36 mloskot: ogr2ogr can eat geojson stuff directly from network resource, like http://
06:25:25 sanova: mloskot, thank you .. i have to read slowly to understand the method
06:25:32 mloskot: strk: do you have suggestion how to automagically tick rt_lib_version on every build?
06:25:57 mloskot: strk: what you think about setting it from $Revision$ for now, so it's easy to identify what you are playing with
06:26:00 mloskot: while testing
06:26:09 mloskot: 0.0.0 does not tell much
06:26:21 strk: I know, $Revision$ would be a step forward
06:27:53 mloskot: I'll set it for now, not ideal as it reports rev of the file, but always better
06:30:02 strk: have ./autogen.sh use revno
06:30:47 CIA-34: mloskot * r3949 /spike/wktraster/configure.ac: [wktraster] Use $ as RT_LIB_VERSION for now, temporarily.

06:46:29 CIA-34: mloskot * r3950 /spike/wktraster/scripts/gdal2wktraster.py: [wktraster] Fixed undefined values in calculate_geoxy function in gdal2wktraster.py.
08:17:36 CIA-34: mloskot * r3951 /spike/wktraster/scripts/gdal2wktraster.py: [wktraster] Issue warning if input raster has no NODATA value and write Zero in corresponding bytes.
09:12:39 : * mloskot is dealing with a very mysterious issue in wktraster, quite funky
09:13:03 mloskot: Anyone intersted, look at discussion + 2 URLs I pasted on #gdal
09:13:04 mloskot: http://logs.qgis.org/gdal/%23gdal.2009-03-31.log
09:13:05 sigq: Title: IRC Log - #GDAL ( at logs.qgis.org )
09:13:13 mloskot: start from 09:04:44

09:15:14 mloskot: bye
10:50:49 tbnorth: hi all - this is OT sry, but what's the best python binding for lat/long <-> UTM conversions? pyproj for proj4?
15:09:34 samgranieri: Hi everyone, i'm new at GIS and I'm stuck trying to figure out how to get latitude and longitude from a shapefile. http://gist.github.com/88465 . If any of you can help, it would be much appreciated!
15:09:36 sigq: Title: gist: 88465 - GitHub ( at gist.github.com )
15:47:44 samgranieri: i actually got it to work
15:48:06 samgranieri: i had to look up the srid online, http://spatialreference.org/ref/esri/102671/postgis/
16:43:29 pramsey: well done, samgranieri, good work for a newbie.
16:43:58 samgranieri: thx
