Thank you very much for the responses. In regards with the feature extraction, the image should have a high spatial/spectral resolution right before you can do this, right?

Hi Everyone, As far as I know, this is impossible and the only way we can do this is by visual interpretation. But out of desperate need of data, the satellite images from Google Earth are all we have to assess damaged sites. I got the images as JPEG from Google Earth and made a mosaic and saved it as TIFF. The mosaic is already true color, but by any chance, does anyone know if there are algorithms/methods how to extract/classify features using a single band or true image? Thank you and I would really appreciate the help. Best, Stella
