comment Using Label classes vs Definition queries - which performs the best?
+1 for your tests. I wonder if it makes a difference whether label conflicts occurs or not? Perhaps you can enlarge the font size so that a lot of lables will overlap. Then disable place overlapping labels option. Is there a difference now?

comment Pie Chart Slice Sizing in ArcGIS-Desktop
You showed an example of how ArcMap displays the chart (field 1: 80,000; field 2: 70,000). Please add a second image how you want the Pie Chart to look.

comment Cumulative field calculation using Python in ArcGIS for Desktop?
What is your real goal you want to achieve? E.g. for NEAR_FID = 1 do you need the results 2, 5 and 7 ? Or it is sufficient if you only get the final result 11?

comment Why is using Bing Maps with QGIS free but not with ArcGIS?
Thanks for the information. "You need to license Bing Maps”. Who is you? The user of the plugin (= I) or the provider/programmer of the plugin?

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).

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.

comment Which UTM zone 32N with prefix should I use in Rhineland-Palatinate (Germany)?
I suggest that you delete the part and the other EPSG-UTM32-Codes. Because other EPSG-UTM32-Codes differ in the order of xy axis. Then I will accept your answer.

comment QGIS DEM (Terrain models) Mode Slope creates wrong data
I am not familiar with USGS-data and capabilities of slope calculation with QGIS. But I would check if xy-units are equal to z-units. If xy-units (e.g degree) are not equal to z-units (meter, feet) the calculation of slope will be wrong.
