Hi Hamish, Yes, copyright has to be taken into account for any data sources you use in your QGIS project. Esp. base maps. Note, f.e. that you cannot use Google Maps as a background layer for your new map. The terms of Google Maps disallow to create any new maps based on their data, if it

Hi Hamish, Your assumptions are right. As the map author, when you are creating new maps in QGIS, you are the copyright owner of your map. However, as Paolo pointed out, if you load data from various sources, you'd have to first check the copyright conditions of the data you use to create

Hi Daniel, One alternative way to do this, without field calculator, is to use the "Processing Toolbox" (see menu processing) and use the "Count opints in polygon (weighted)" algorithm. This should do what you want, but the downside to this approach is that you end up with a new layer. If you

If I remember right there was some restriction on the project projection. It probably has to be EPSG:4326, but I am just going from memory. If you are just doing a fixed rectangle, ellipse, or some polygon such as an octagon, you could see if the "Shape Tools" plugin would do what you need.

Hi Marianna, From what you are saying it sounds like you have a raster with pixels/grid values 0 or a 1? I think what I would do is some “binning”. You can create grids to the desired size with the mmqgis plugin so you could make a 100 hectare grid and then run the zonal statistics plugin to
