comment Thermal Map Data
In addition to comment of Chris W (low spatial resolution of satellite images) I would like to add: In the company where I worked we always used a cutom airbore thermal scanner data collection to determine the time of the data acquisition. In our urban climate studies we were interested in two times to analyze heat flow: one flyover shortly before the sunrise and another flyover shortly before the sunset. This is not possible with satellite data.

comment How to switch off symbol when label is unplaced due to conflicts?
Since you are looking for a dynamic solution (work when zooming) I would try this: do not display the circles as symbols of a feature. Use the label engine to display the circles as a label. Your label is composed of two parts: the circle and the text.

comment How to place labels under a vector layer?
Is the text “Erlenring” a label of the red/blue line layer? Or does the label “Erlenring” belongs to a second layer (e.g. to the white street polygon)?

comment Eye-friendly colours for long periods of work
+1 for your recommendation of a light background (light grey, light colors) and the interesting links at UX. If you have a paper draft I would not recommend a dark background (your eyes then have to switch between light paper and dark screen while digitizing).

+1 I found FWTools 2.4.7 at softpedia.com. It works. Thanks.

comment Print maps with a specific scale
+1 But I do not understand your calculation. 1200 km² = 35 km x 35 km. To print this area with a scale of 1:25000 you need a paper of 1.4 m x 1.4 m.

If you try to select points with a rectangle: are the points selected (highlighted) in the attribute table?
