So, I've found the cause of the issue: [Project properties]_[Project Home] must be blank. Also: No need to set the 'Referencing Field' (aka foreign key, i.e. fkid in my example) to a Relation reference. I have Relation set to 'Association' strength - I have not tested 'Composition' strength. O


I think you mean that you want the mean attribute of the "joined" feature to be a property of the parent feature, right? var DatFlat ={ var joinedFeaturesList = ee.List(mainFeature.get('mean')) return mainFeature.set('mean', ee.Feature(joinedFeaturesList.get(0)).get('mean')); }); print('DatFlat', DatFlat)

I've researched your trouble with the MMQGIS spatial join option. From what i've seen the problem is that the grid you've generated was a line layer. The MMQGIS does not support a spatial join operation between a point layer and a line layer. In the MMQGIS documentation says that: "Spatial Operation: Indicates the spatial relationship that should be ...

Assuming you have one geoseries with Points (for example you want to compare Point 1 to Point 2, Point 1 to Point 3,... ): import geopandas as gpd from itertools import combinations from shapely.geometry import LineString df = gpd.read_file(r"C:\data\vk_riks_Sweref_99_TM_shape\vagk\riks\js_riks.shp") series = df.geometry max_distance = 15000 ...
