comment How to obtain the optimal parameters in LSMS Segmentation Monteverdi2?
there is no unique threshold that solves any segmentation problem. first thing to do is to look at the texture of your image (to get a grip on the spatial range) and the internal variability (to get a grip on the spectral range). If you provide more information about your image, maybe someone could help.

comment Using Con with Hydrology tools in ArcGis Dekstop
the first two errors are most of the time related to lack of memory or absence of writing permission to the directory. Have you tried to run the tool out of model builder?

comment Clipping rasters
+1 for deriving the extent. you can either use the rectangle (second parameter) or the studyarea (4th parameter). As written you should replace one of those parameters with "#", and the "" after studyarea should be removed.

comment Get min/max value of each band from landsat image?
It seems that Gdal does not recognize 0 and 65535 as the NoData value GetMinimum is meant to ignore the NoData values). Try to set those values to NoData using SetNoDataValue. Can you edit your post with a print of "gdalinfo -stats"

comment Best way to copy GDAL metadata from one JP2 image to another
Basically, you have information about the reference system, but no specific metadata. I think that what you need can be done with gdaledit.py, so you should have a look at it.

comment SRID is messed up when google-maps layer is added
your data falls near the 0,0 coordinates of mercator. I suggest that you try to change the SRID of your postgis data to 4326
