Assuming we have high resolution satellite imagery (multi-spectral raster image) of a large urban area, then how can Python be implemented for the extraction of impervious surfaces?
@Rakesh: Thank you for your suggestion. I have been already using Object-based Image Analysis (OBIA) of ENVI software. However, there are some classification inaccuracies as well that have been identified. For an improved analysis with more accuracy, Python programming can be the best tool for the extraction of impervious surfaces features. That's why I emphasized more on Python in the question.
