| 01:35:10 | rullzer: | hi, I have a geom objet ( LINESTRING ) is it possible to split it into lines so I get all the parts the LINESTRING is constructed from? |
| 01:51:55 | CIA-34: | strk * r2513 /trunk/ ( ChangeLog.svn Makefile.am authors.svn ): |
| 01:51:55 | CIA-34: | Add a rule to generate a ChangeLog using svn2cl. The authors.svn file will be |
| 01:51:55 | CIA-34: | used to map usernames and full names: please expand your own nick. The generated |
| 01:51:55 | CIA-34: | ChangeLog is added to repository to show you how it looks. If everybody agree we |
| 01:51:55 | CIA-34: | could rename this to ChangeLog and stop requiring manual edits ( +1 from me: ) |
| 02:03:52 | CIA-34: | strk * r2514 /trunk/ ( ChangeLog.svn Makefile.am authors.svn ): Add Mat's and Paul's entries, make ChangeLog.svn rule phony |
| 06:43:11 | strk: | GEOS wishes anyone ? |
| 07:15:41 | : | * bitner wishes someone would make an sdeemu equivalent to sit in front postgis ala the old imsemu in front of mapserver, really doesn't want to shell out for ArcGIS Server |
| 10:51:01 | DavidAndCarr: | is there a way to query and create a box based off a lat/lng point with a distance of 5 miles off that point? so I pass in a lat/lng and a radius distance, and I'm returned a NW and SE lat/lng pairings? |
| 10:52:15 | springmeyer: | buffer the point and take the extent of the resulting polygon |
| 10:56:30 | DavidAndCarr: | :: googles that :: |
| 10:58:42 | jlivni: | better: use box2d or buffer( geom,1,1 ) |
| 11:02:41 | jlivni: | DavidAndCarr: that last param is the # of segments per 1/4 circle, so a value of 1 means you get a box |
| 11:02:52 | DavidAndCarr: | gotcha |
| 11:02:59 | jlivni: | but i think st_box2d might be the smoother method |
| 11:03:03 | DavidAndCarr: | thank you : ) |
| 11:04:40 | jlivni: | DavidAndCarr: should mention that to get miles you need to transform the lat/lon to a projection where distance makes sense |
| 11:04:52 | DavidAndCarr: | ok |
| 11:06:07 | jlivni: | eg st_buffer( st_transform( orig_geom,1234 ),5*1609,1 ) |
| 11:06:19 | jlivni: | where 1234 = epsg code of your chosen projection |
| 11:06:28 | : | * jlivni gets lunch |
