comment Classifying type of land use each spectral represents from remote sensed data?
Hi PROBERT - it'd be helpful if you edited your question to add a scenario you're working with - as your question stands, the answers are subjective. The answer to the first question is usually that you "train" the classifier by interpreting the imagery yourself and telling it what specific areas mean.

comment Can I install two versions of QGIS on the same computer?
Anyone finding this now and @mapsir, a file ending in ".md5: is a hash file, which can be used to verify the integrity (and sometimes authenticity) of a file. You can feel free to ignore it and just download the one that only ends in .exe

comment How to Lock Grid and Scalebar in QGIS Atlas
Coming at this same problem much later...I don't see an atlas group when editing the scale bar's item properties (QGIS 2.4). Setting a fixed scale has worked nicely for me on overview maps, but not for scale bars yet.

comment Does QGIS support .sld style files for raster layers?
Having the same issue - research is showing that the answer may be "no, it doesn't" - I'll let you know if I find anything

comment DTM Extraction/Smoothing in ArcGIS
Have you tried making a LAS Dataset and manipulating it using the LAS Toolbar built into 10.2? It helps you classify data - you can view by cross section, etc. You could then subset to the points you want - There's a pretty robust LAS Dataset to TIN tool.

comment Are there any attempts to replace the shapefile?
I know this is really delayed off the original, but as an update in case anyone else finds this - ESRI quietly (very quietly) added Spatialite support to ArcGIS 10.2. So far, using it is pretty seamless, but the databases can only be created in ArcPy (but used everywhere). Converting tables with large text fields also seems to be a problem, but it's otherwise workable

comment Errors while running Region Group tool
I'm always inclined to listen to @whuber, but if you were trying to debug this yourself further, try using GRID format inputs and check your scratch directories in your environment settings. Spatial Analyst is often fickle about personal/file geodatabase datasets in my experience. The only way this works though is if the tool manages to chunk the data so as not to load it all at once. Not sure if Region Group can do this or not.

comment Cannot install ArcGIS for Desktop 10.2 following install guide on Windows 8
Also adding to @MichaelMiles-Stimson - in Windows 8, no need to extract or use Daemon tools - Win8 will mount an ISO as a CD drive natively.

comment Optimising map cache creation performance in ArcGIS for Server 10.2.1
Try opening up Resource Monitor and see if anything is hammering the hard disk. You can also check with something like sysinternals procmon, but my experience with ArcGIS is that I'm bound by disk I/O much more often than CPU.

comment How to improve performance when using ArcGIS cursors in Python with big tables?
@StéphaneHenriod - as a suggestion, you might consider editing the question to add these additional specifications. Given the initial question, I think this answer makes tons of sense, but with this new information, Barbarossa's answer looks good.

comment Why is GPS a free service?
Yeah, but their competing system is also available for public use, so expect devices to use both in the future. The Garmin GLO uses both for additional precision (more satellites in the sky).
