| 05:37:02 | smartnude: | I've got a multilinestring that I want to interpolate a point on, I guess I first need to convert it to a linestring for use with st_line_interpolate_point ? I tried using st_linemerge on my multiline, but did not help.. any tips ? |

| 12:36:06 | zanberdo: | is there a function to return the perimeter of a polygon? |
| 13:03:35 | drewby: | Hi, does postGIS have any line smoothing algorithms? |
| 13:08:59 | jlivni: | drewby: st_simplify |
| 13:14:27 | rudenstam: | zanberdo: st_perimeter ? |
| 13:16:31 | drewby: | simplify doesn't really make stuff smoother though, it makes stuff more jagged most of the time |
| 13:18:08 | drewby: | I need more of a standards compatible fit to curve. |
| 13:20:57 | cgs_bob: | drewby: sorry for being a bit off topic, but GRASS has a nice line smoothing algorithm. take a look at this: http://grass.itc.it/grass64/manuals/html64_user/v.generalize.html |
| 13:20:59 | sigq: | Title: GRASS GIS manual: v.generalize ( at grass.itc.it ) |
| 13:21:58 | pramsey: | "standards compatible" ? |
| 13:29:23 | strk: | woof |
| 13:29:36 | strk: | I bet it's the same algorithm |
| 13:31:53 | jlivni: | drewby: you may be interested in this thread http://groups.google.com/group/geodjango/browse_thread/thread/130800c6255fd1e0 |
| 13:31:55 | sigq: | Title: alternatives to simplify( ) for reducing points in polygons - geodjango | Google Groups ( at groups.google.com ) |
| 13:32:27 | jlivni: | different people have different ideas of what smoothing should do, and when. the paper describing the VW algorithm from the mapshaper.org guys gives a nice overview |
| 13:32:55 | jlivni: | pramsey: i think by standards compatible he means the simplified output needs to be WFS? |
| 13:33:40 | : | * jlivni wonders what the 'snakes method for line smothing is' .. gotta try out this v.generalize now |
| 13:33:54 | strk: | toGml( simplify( ) ) ? |
| 13:34:05 | jlivni: | heh |
| 13:34:27 | jlivni: | or maybe kml is the standards now ... tho its getting less simple by the release |
| 13:42:08 | strk: | pramsey: does obe ever get around here ? |
| 13:42:51 | pramsey: | v. rarely |
| 13:43:01 | pramsey: | I try to goad her, but no real luck so far |
| 13:43:06 | pramsey: | she is immune to the call of im |
| 13:45:36 | jlivni: | and v.rarely is, almost surprisingly, not a grass module |
| 13:45:56 | : | * jlivni shuts up, realizing switch to matte from coffee is making him say silly things |
| 13:48:19 | : | * pramsey is futzing with jmeter and getting some database benchmarks ready |
| 13:48:20 | pramsey: | jmeter == pretty damn awesome |
| 15:17:37 | strk: | jumping to the java side ? |
| 15:17:47 | : | * strk talks alone... |
