| 00:09:19 | Viivi: | hi, question about creating polygons from linework |
| 00:10:09 | Viivi: | using polygonize on linework like this: http://globus.eomap.ee/test/postgis/shape.png will create only one big polygon, right? |
| 00:47:16 | Viivi: | nope, my mistake, polygonize works as espected : ) |
| 03:56:40 | mlechner: | hi, i need a print-quality ( or vector ) version of the official postgis logo - where can i download it? |
| 04:15:30 | CIA-3: | robe * r4182 /trunk/doc/installation.xml: fix type and add --with-gui description for building loader gui |
| 06:14:19 | CIA-3: | robe * r4183 /trunk/doc/reference.xml: typo in docs -- |

| 09:25:41 | CIA-3: | [wktraster] windownsample.py: implemented mechanism of appending padding pixels |
| 09:25:41 | CIA-3: | to the right-most edge of raster. For instance, read 4x4 raster as 8x4 and 4 |
| 09:25:41 | CIA-3: | pixels of padding are appended to the right edge. Should work with changing |
| 09:25:42 | CIA-3: | resolution. |
| 11:39:16 | TJCRI: | can postgis do conversion from say lat/lon to a diff. projection? |
| 11:39:21 | TJCRI: | on the fly |
| 11:45:57 | darkblue_B: | yes |
| 12:04:14 | pramsey: | select st_transform( st_setsrid( 'POINT( -126 40 )',4326 ),26910 ); |
| 12:04:56 | pramsey: | select st_astext( st_transform( st_setsrid( 'POINT( -126 40 )',4326 ),26910 ) ); |
| 12:09:00 | darkblue_B: | when do you need GeomFromText( ) and when can you just say POINT as a literal like that? well, no matter because you rarely have hard coded data in queries I'd guess |
| 12:09:30 | darkblue_B: | the box2d data type cast |
| 12:09:51 | darkblue_B: | I fumble around with that every time |
| 12:10:33 | darkblue_B: | the 1.4 manual is sooo much better |
| 12:10:49 | darkblue_B: | what a great undertaking.. its been a while now |
| 12:18:28 | darkblue_B: | TJCRI: PostGIS 1.4 manual, FAQ 3.8 "How do I pefoem a coordinate reprojection as part of a query ?" |
| 12:19:56 | darkblue_B: | ok, section 4.1.1 goes into some detail about valid represenations |
| 12:20:38 | darkblue_B: | 4.1.x |
| 12:22:15 | darkblue_B: | aha faq.xml in trunk |
| 12:23:19 | TJCRI: | thank you pramsey and darkblue_B |
| 12:24:11 | TJCRI: | that seems like it will work perfectly |
| 12:24:40 | darkblue_B: | TJCRI: you're welcome.. its an undertaking, this system.. I find it clearer than the small bit of Oracle I've done |
| 12:25:18 | TJCRI: | well I just have to jump in the lake and get wet .. which I will be doing with this project i have going on : ) |
| 12:25:42 | TJCRI: | so far I have just dabbled my toes to get a feeling for it but soon need to jump head first |
| 12:26:34 | darkblue_B: | here is a reasonably recent 1.4 doc build |
| 12:26:50 | darkblue_B: | http://71.202.181.1/postgis/ |
| 12:26:51 | sigq: | Title: PostGIS 1.4.0SVN Manual ( at 71.202.181.1 ) |
| 12:26:53 | TJCRI: | what is the proper name for the projection #? for example: 4326 ? how would I ask for that number based on a projection name? |
| 12:27:13 | darkblue_B: | those numbers correspond to entries in the spatial_ref_sys table |
| 12:27:49 | TJCRI: | ok so If I have MI State Plain NAD feet I should be able to find a corresponding number? |
| 12:28:02 | darkblue_B: | which could be anything literally, but correspond to conventions on ESRI and EPSG numbering schemes |
| 12:28:38 | darkblue_B: | http://spatialreference.org is handy |
| 12:28:39 | sigq: | Title: Home -- Spatial Reference ( at spatialreference.org ) |
| 12:28:45 | TJCRI: | ah EPSG numbering scheme ok so thats what I have to compare probably |
| 12:28:51 | darkblue_B: | sometimes its hard to search though |
| 12:29:50 | TJCRI: | well I have a nice listing for MI here: http://spatialreference.org/ref/epsg/?search=michigan&srtext=Search |
| 12:29:51 | sigq: | Title: Spatial Reference List -- Spatial Reference ( at spatialreference.org ) |
| 12:32:41 | TJCRI: | well it looks like I need EPSG:2898 |
| 14:27:37 | CIA-3: | strk * r2593 /trunk/capi/ ( geos_c.cpp geos_c.h.in geos_ts_c.cpp ): Extend the C-API interface to expose a GEOSBufferWithStyle ( and corresponding thread-safe version ) and related enums. |
