comment Best Landsat-5 TM band combination for detecting fire scars
Based on single post-fire data sets, Pu and Gong (2004) also report that TM 4 and TM 7 are the best burned area discriminators. Among the visible channels, TM 1 and TM 2 were identified as the most useful in the multitemporal and the unitemporal studies respectively. | Pu, R. and Gong, P. (2004). Determination of burnt scars using logistic regression and neural network techniques from a single post-fire Landsat 7 ETM+ image. Photogrammetric Engineering and Remote Sensing, 70(7):841–850.

comment Best Landsat-5 TM band combination for detecting fire scars
Just adding a few more words on the subject: According to Koutsias and Karteris (1998, 2000), the spectral channels TM 4 and TM 7 provide, in both multitemporal and unitemporal data sets, the highest and second best burned area detection ability respectively.

comment How to convert shapefile to mapinfo file preserving special characters?
(Late Reply!) Can you use QGIS? Import the Mapinfo file in question, set the correct encoding in Layer Properties > General (Tab), then Save As anything QGIS supports (via GDAL/OGR).

Thank you @Kurt, this was the right direction for some Mapinfo vector data with lots of Greek Fields/Strings.

comment How to reference a specific layer in a dataframe with Arcpy
Dear John, maybe you could link to the link to the other answer. As answers are resorted based on votes, a reader wont be able to identify the other answer you are referring to. Also, you could emphasize the code lines by either using the backquotes ` (to wrap short text of code) or use the appropriate button (curly brackets) provided for code blocks when it comes to larger pieces of code.

comment Line segment connectivity analysis in FME
@BillKinkaid I would rather put this as a comment and/or try to make a point in another way (maybe pointing to other discussions of a related FAQ, e.g. meta.stackexchange.com/questions/17845/…). I would avoid, however, to dedicate an answer for this.

comment How to delete a base map in GRASS?
Using native grass modules is safer, in any case. Also, one can force the removal of any map by issuing the force flag, i.e.: g.remove rast=raster_Mnorzagaray -f.

comment How can I convert SRTM data to DEM or DTED?
Maybe FTP is preferred for various reasons (e.g., sometimes to "respect" bandwidth limits) but for me it was/is always the slowest path.
