This question already has an answer here:
Currently I am compiling a FAQ for my company on QGis, since some people feel the need to work more with QGis. I am the person to go to, when some specific problems appear, but I see a need to give people something to consult with instead of letting them blunder along.
Currently I have the following topics in my FAQ (either already fully explained or at least with some notes):
- Limits of QGis
- Terms & User Interface, e.g. layer & layer properties, vector vs. raster, CRS, tools, snapping,
- Data types, as shape, dxf, kml/kmz, csv, images, qgis-style, project files, geopackage, wms
- important, reoccurring tasks/workflows, as georeferencing, manipulating attribute tables, geometry validity, clip, dissolve, buffer, creating geometries
I also try to include all tricks I use regularly or built for others in my company, like automatically adding attributes to a newly created feature, or trying to determine if a polygon is about the desired size.
