Bonjour, Je désirerai savoir s'il est possible, dans cette nouvelle version de Qgis 2.6.1, de modifier un fichier *.TAB ? Si oui, comment s'y prendre ? Car j'ai mis la couche en EDITION. Je peux éditer les cases dans la table seulement quand je valide elle reprend la valeur par défaut...

Bonjour, cette fonction de légende wms apparue récemment est très intéressante sauf que je n'arrive pas à l'afficher. Je coche bien la case "utilise la légende wms contexte" mais rien ne s'affiche. Cela viendrait de la couche wms (qui n'aurait pas de légende)? ou d'une erreur de manip...

The QuickOSM plugin for QGIS can support users with the generation of new Overpass queries (for beginners on Overpass like me). It does this using the xml query language. I'd like to also be able to use this plugin with the alternative Overpass QL format. So far I've failed to do this despite...

I want to add some kind of commenting functionality for users to leave notes on a map. I know that Esri deprecated the "add pop up" element in 2.3.1 because it didn't save. My current thinking is to direct users to create a circle feature and add their comment as an attribute using the "Edit"...

I read everywhere that Leaflet is internally using a spherical web mercator (EPSG:3857), but whatever I try I get either Lat/Lon (EPSG:4326) or strange coordinates I dont understand: map.getBounds().getNorthEast(); // LatLng(52.5262, 13.44907)map.getPixelBounds().getTopRight(); //...

Within the survey point data my attribute table contains the percentage responses to a number of binary questions for...

I'm looking for a qml file (or equivalent e.g. sld) to allow me to use QGIS to take Openstreetmap data and produce paper maps. I'm re-asking this question (it was asked once or twice over a couple of years by other people) because I'm really surprised not to easily find such a thing already (I...
