I would like to set up a simple web map which should be used as an information for those out in the field that needs to show something immediately. So I would just load the web map and get an overview. The thing I would like to have is a map normal background map and then the user should be able to draw a polygon/point/line and that polygon should then be stored in a database or on the server.
For now I am going with Leaflet and QGIS.
Could someone tell me how it do this or provide links?
