Hi, I'm having a classical use case here. Before starting a new plugin, and since it is a very common task in GIS, I would like to know if anyone has made something alike:
- I have a postgis db with LINESTRINGM routes (watercourses already calibrated with measures). - I have a non geometric table registering events with start and end measures + identifier of my routes (watercours ID). - I create my event in the attribute table, with one ID and two manually typed measures, then a view cast it to spatial view using locate_beetween_measure function. I would like to create a form with two tools dedicated to "pick up" my route and the measure. i've done it in Arcview 3.2 once in the old past.. What could be the current better and simpler approach in QGIS? LRS plugin does not have that feature, and requires to recalibrate layers from scratch. Could we dream for the future of a new generic form widget with custom expressions to get attributes or geometric information from a layer (with snapping options )?
