How and where to get bounding boxes of places / POIs? Preferably, for free. For example, on OSM I can see a place drawing displayed on a may and with zooming-out one can see corners as latitude and longitude.

They are needed to test a coordinate against the bounding box in a query.

  • Do you mean actual points as your POIs, or a set of points?

Assuming you already have the polygons of the places you want to analyse (e.g. exported from OSM) you can create the bounding boxes of the polygons by using the function Polygon from Layer Extent in QGIS. You can find it under Vector - Research Tools. Make sure to check the option Calculate extent for each feature separately.

For a single point of interest it is not possible to create a "traditional" bounding box, since a point does not have a spatial extent.

  • I do not have polygons of the places to analyze, I am trying to grab them. Where it's in form of boundig box or polygon, I need to extract a spacial representation of places.

  • If you want to get the places from OSM, you can look up e.g. at the OSM Wiki if there is a specific tag for the place(s) you like to analyse. Then you can export them e.g. with the overpass-turbo api. There's a link directly to overpass-turbo at every wiki page for a tag. Commented Oct 18, 2016 at 7:07
