| 07:43:09 | jalmeida: | in postgis exist some function for network, ?? |
| 07:43:40 | jalmeida: | similar to oracle database manager ??? |
| 07:44:44 | bitnerd: | jalmeida: I don't understand what you are asking / am not familiar with oracle databse manager |
| 07:46:06 | jalmeida: | bitnerd, in postgis exist some finctionality for short and path ?? |
| 07:47:32 | bitnerd: | short = shortest distance along a network?? |
| 07:47:52 | bitnerd: | I still don't quite know what you are asking |
| 07:49:16 | jalmeida: | yes sorry shortest path |
| 07:49:39 | bitnerd: | do a google search on pgrouting |
| 07:50:05 | bitnerd: | routing is not built in with postgis, but pgrouting is built on top of postgis and provides for routing functionality |
| 07:51:43 | jalmeida: | ok , thanks |
| 10:41:40 | synsol--: | can someone explain what an SRID is, does it have to be unique for every record? |
| 10:42:31 | bitnerd: | no, in fact it generally is constrained to be the same for all records in a table |
| 10:42:41 | bitnerd: | it is the Spatial Reference Identifier |
| 10:42:58 | synsol--: | thats what i thought, since it is specified in the migration using georuby |
| 10:43:05 | bitnerd: | it is a code that basically says what coordinate system the data is in |
| 10:43:31 | bitnerd: | it refers to data that is stored in the spatial_ref_sys table |
| 10:44:03 | synsol--: | what do you mean by coordinate system, like if all i was storing was long/lat info for google maps, would it all be the same SRID if it was using the same map |
