After obtaining properties(contrast,homogeneity,entropy) using glcm
what is specific range of contrast for vegtation,waterbodies
and how to assign colours to different range of values of (say contrast) to classify into vegetation,waterbodies etc
thank you for the guidance.

Wiki:
Contrast is the difference in luminance or colour that makes an object (or its representation in an image or display) distinguishable. In visual perception of the real world, contrast is determined by the difference in the color and brightness of the object and other objects within the same field of view. The human visual system is more sensitive to contrast than absolute luminance; we can perceive the world similarly regardless of the huge changes in illumination over the day or from place to place. The maximum contrast of an image is the contrast ratio or dynamic range.

The question is purely subjective
"what is specific range of contrast for vegtation,waterbodies"
Contrast consider as the dynamic range of pixel values, if the image having all pixel values (within it range), then it is consider as a good contrast image (see the histogram profile) I dont think constrast may consider specificall based on things (vegtation,waterbodies).
Are you looking for segmentaion for vegtation,waterbodies from the image.
"how to assign colours to different range of values of (say contrast) to classify into vegetation,waterbodies etc"
Better you should look for color levels or composition (not contrast), or color thresholding
Good Luck!
