Good morning, I have a PostgreSQL database of several million points with latitude/longitude and I would like to do the following with qgis-server or PostGis: according to a number of shapes (hexagons, circles or squares) per mesh, calculate the number of points per shape and color the shape darker as there are points underneath. If there are no points the shape should not appear. If we zoom in, the meshes must be recalculated and reduced of course. On the other hand I would like a leaflet basemap. Thank you for your help, Kind regards Sylvain Ard Sylvain Ard 0549507724 0778380991 sylvain....@gmail.com http://sylvain-ard.fr Entreprise individuelle SIRET : 80079243400022 Appt 26 Bât A Résidence Le Patio 83 rue de la Bugellerie 86000 Poitiers
