QGIS Python (PyQGIS) - Measure distance between features

[@aldricbastid2079]

My loop does not work, only the first line appears, despite having the same code

[@joaofolgado3316]

what can i do to measure the distance of two features using ellipsoidal measuring. my project use WGS84 ellispoid. so, the measuring of the functions distance() is very different of the measuring i do manually. can you help me ? thank you very much

@@geospatialschool I had already see that. So the idea is to use the processing algorithm that create points around the polygons and use the code on that link to return the more closest? Can you tell me if the distance functions use this way to return the closest distance between the two polygons?

I am trying to add all polygon that are under the radius(300m) of my selection polygon, do you have any tutorial for that ? thank you very much

You can buffer the polygon of interest by 300 m, then find all the polygons that intersect the buffer
