| Oct 10, 2012 at 17:12 | comment | added | spatialhast | @ALL, Is it possible in PostGIS create next query: create point layer from start/end vertex linear layer, then find in point layer points where 'two' duplicated coordinates (is it pseudo nodes)? | |

| Oct 10, 2012 at 7:15 | comment | added | spatialhast | @Rayner, add new image of examples pseudo nodes: if I receive for linear layer point layer pseudo nodes (blue rects) I corrected next errors in linear layer: A - add missing geometry, B - snapped line in intersection, C - remove pseudo node. Thanks! | |

| Oct 10, 2012 at 6:31 | comment | added | Rayner | @HasT, just want to confirm one thing. Are you looking for actual pseudo nodes (where line start/end points aren't snapped) or are you looking for points where you have two (and only two) lines connected (and snapped)? | |

| Oct 5, 2012 at 9:42 | comment | added | spatialhast | @Kurt, Add new image: 12 linear features with three pseudo nodes in A (line 4/5),B (line 6/7),C (line 9/10). Instead pseudo nodes should be shape-points - two linear features with interction in one point (node) should be one linear feature (line 4/5 - line 4, ...). Thanks for the help. | |

| Oct 5, 2012 at 9:19 | comment | added | Kurt | @HasT, please give me some advice. as vinayan said the red poitn is an intersection of two valid gemometries. what do you mean with shape-point?? | |

| Aug 16, 2012 at 17:49 | comment | added | spatialhast | @Giovanni Manghi "yes, you can use them within QGIS in any tool that allows you to run a PostGIS query, like for example DB Manager (that supports syntax highlighting and auto completion)" - Can you write steps how I must use 'Is_Valid' and 'Makevalid' functions for searching pseudo nodes. I newer using in postgis database functions... Thanks! | |
| Aug 16, 2012 at 17:46 | comment | added | spatialhast | "the red point in the second picture is an intersection of two valid geometries..right?" - yes, it is intersection of two geometries. On the red point (node) should be shape-point. | |

| Aug 16, 2012 at 13:31 | comment | added | spatialhast | Yes, I use PostGIS 2.0. How I should use these functions for searching pseudo nodes? Is it possible to find them with "PgQuery for QGIS"? | |
| Aug 16, 2012 at 9:19 | comment | added | gioman | Do you use PostGIS 2.0? If yes, give a try to Is_Valid and Makevalid functions. | |
| Aug 16, 2012 at 7:58 | comment | added | spatialhast | In GRASS exist command rmdangle, but in result shp-file without pseudo nodes. In result should be shp-file (or another) of pseudo nodes (like gvSIG OA Digital Edition 2010) | |
