To create dynamic leader lines I use the QGIS „Move Label“ tool and a PostGIS view. CREATE VIEW leader_line ASSELECTgid,ST_MakeLine(geom, ST_SetSRID(ST_MakePoint(xcord_label, ycord_label), SRID))::geometry(linestring, SRID) AS geomFROM pointWHERE xcord_label IS NOT NULL;This works fine for all...

Before I ask my question, I want to say upfront that I am woefully inexperienced with coding as well as GIS, which is part of the reason why I'm here. I am currently working on a project where I am using Census tract data to figure out the population characteristics of the city council...

I am trying to get the nearest node from a point(Id 1) . The coordinates (lat/long) are input by an user . I am using some functions like pgr_nearest_node() or get_nearest_node() from get_nearest_node function reference 1: http://www.sqlexamples.info/SPAT/postgis_nearest_point.htm. The Problem...

I receive a gml-like response from a RESTful Web service. It looks good for me but I can not imported in QGIS. Is there an online validation tool for a valid gml file? Or am I missing something for the schema? The response I received is as 41.0296010971069...

I have a series of points in a trackset but I don't have the order or timestamp of the points. I'd like to combine them into a polyline. Is there a more sophisticated ordering algorithim than [lat,long] or [long,lat]? Should I perhaps order them in both orders, then take the average of the order...

I do not want to manually fix one at a time. I have a way of selecting all the overlaps (through intersecting the layer by itself) but...
