| 13:42:30 | someotherdude: | noob licensing question |
| 13:42:45 | someotherdude: | what is the postgis jdbc licensed under? |
| 13:45:14 | someotherdude: | nevermind, found it |
| 17:05:57 | brough: | have a bit of a design prob looking for lines that cover one anoter. geom_a: '1----4' covers geom_b '1----4' also coveredby a union of geom_c and geom_d: '1--2/2--4'. the geom_a covers geom_b query is fast and easy. is there a simple way of finding if geom_b is coveredby a combination of geoms? |
| 17:09:20 | brough: | I just need to return true if geom_a covers a geometry on table_b with a particular foreign key ( obviously trivial ), or return true if geom_a is exactly covered by two or more geometries on table_b of the same foreign key. |
| 17:09:57 | brough: | ie the 'matching' geom on table_b can be broken up. |
| 17:13:06 | brough: | I think creating a union of all geoms on table_b, on union for each fkey condition, and querying those unions, would be the fastest way? |
| 17:13:23 | brough: | *one union for each foreign key condition. |
