comment Getting NameError when using Cursors to read vertex coordinates in ArcPy?
+1 This is a more efficient approach than integrating the feature geometry into near via a for loop.

comment How to classify difference surfaces having almost similar Reflectance responses?
It is common to incorporate data such as indices into your classification algorithm. Here is an example of improving wetland classification accuracy by incorporating NDVI and texture with spectral bands: mdpi.com/2072-4292/6/12/12187/pdf.

comment Auto populate a field in a dbf table
Welcome to GIS SE dave. Please edit your question to include 1) your software, 2) an example of the input data and the intended output, 3) A clear, answerable question. Once those critical components are in place, vote to reopen the question.

comment Automatic point plotting in ArcGIS from thresholded image
Check out this thread: gis.stackexchange.com/q/166753/8104. Essentially, they convert the raster to contour (polyline). Then you could simply convert the polyline vertices to points. This may be a more efficient approach than converting raster to points directly, Additionally, this approach will have the added benefit of being able to filter out line segments smaller than some threshold to remove the extraneous features (i.e. prior to converting to points).

comment How to classify difference surfaces having almost similar Reflectance responses?
No, you do not need to use rule based classification to incorporate spectral indices (SI) into your classification. You can simply add the SI as another band into your classification algorithm (e.g. supervised maximum likelihood, random forests, etc.).

It appears that bands 1,2,3 have good differentiation. I would also think that asphalt/concrete would have a different thermal profile compared to exposed bedrock. Have you tried incorporating spectral indices into your classification algorithm? landsat.usgs.gov/documents/si_product_guide.pdf.
