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.

@Stephen Lead - OK, I posted my suggestion as an answer to Removing features whose labels are not displayed?.

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 Are there another way/tool as GDAL/ERDAS-API to convert a raster to ECW?
+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.

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.

Can you give more information about crime rate data set (raster/vector, point/polygon, fields, ...)? Do you have ArcGIS Spatial Analyst?

comment How to make polygon volume in TIN surface?
Sorry, I've swapped the tools. Correct is this: Calculate in special area of interrest: Polygon Volume (3D Analyst). Calculate for whole TIN: Surface Volume (3D Analyst).

comment How to make polygon volume in TIN surface?
Do you really want to calculate the volume in a special area of interest (e.g. your TIN covers Europe but you want to calculate only in area of Norway)? Then use Surface Volume (3D Analyst). Or do you want to calculate the volume for the whole area (e.g. your TIN covers Europe and you want to calculate the volume in Europe)? Then use Polygon Volume (3D Analyst).

comment How can I make a reference plane to measure surface volume?
This is a new question. So I suggest that you start with a new question at /gis.stackexchange.com. Then you should give details about the software you have (3D Analyst, Spatial Analyst, …), about the data you have (TIN, Raster, …) and what you want to achieve exactly. Describe the target you want to achieve.

comment Interactive Exports from GIS
HTML ImageMapper does not work with Mapinfo. There are probably many similar tools like HTML ImageMapper. An other aproach is to Export SVG instead of HTML. Mappetizer (ArcGIS) and SVGMapMaker (Mapinfo) export to SVG (I have both not yet used.) I assume that there is no tool with works with ArcGIS and Mapinfo.
