03:38:15 unlord: hi
04:33:55 unlord: does anyone know what CRS Google Maps returns?
04:49:41 tazle: geographical coordinates on WGS84?
06:06:28 unlord: tazle: yes
06:06:46 unlord: I believe its EPSG:4269
06:07:35 tazle: uhm, perhaps 4326?
06:07:56 unlord: could be, I don't know for certain
06:08:08 tazle: why are you making bad guesses, then?
06:08:34 unlord: well, currently I'm just trying to debug my transforms
06:09:50 tazle: what are you tryingto convert it to?
06:10:17 unlord: I was following an example that converted the points into 32661 so that distance comparisons would be in meteres
06:11:23 unlord: using postgis: transform( setsrid( makepoint( -95.677068,37.0625 ),4269 ),32661 )
06:12:03 tazle: well, 4269 is certainly wrong - where did you get that?
06:12:35 unlord: http://www.bostongis.com/?content_name=postgis_tut03
06:12:38 unlord: just following this guy
06:12:39 sigq: Title: Part 3: PostGIS Loading Data from Non-Spatial Sources ( at www.bostongis.com )
06:13:42 unlord: Often you will receive data in a non-spatial form such as comma delimited data with latitude and longitude fields.
06:13:48 tazle: unlord: did you read the part where it said that 3269 is NAD83 lonlat?
06:14:02 tazle: err, 4269 is NAD83 lonlat
06:14:13 unlord: ooooohh
06:15:09 unlord: thats very important, but that doesn't change the problem I'm seeing
06:17:17 unlord: oh wait, but it does
06:17:25 unlord: except my lat/long's are swapped
06:17:28 unlord: let me spend sometime iwth this
06:22:00 unlord: I think the geotools API wants it latitude,longitude and the postgis code wants it longitude,latitude
06:22:56 unlord: either that or their 32661 transforms are different
06:28:47 CIA-6: mcayland * r2779 /trunk/topology/ ( Makefile topology.sql.in topology.sql.in.c ): Update topology/ directory to use the new PGXS build system.
06:32:12 CIA-6: mcayland * r2780 /trunk/ ( configure.in doc/Makefile.in ): Update documentation build so that "make install" now works. Maybe this will fix the on-line website build?
12:40:45 CIA-6: mcayland * r2781 /trunk/lwgeom/ ( 13 files ): Since PGXS compiles libraries with -Wall, attempt to remove as many warnings as possible. Most of these are missing function prototypes at the top of each file.
