The image attached is of Landsat-MSS, 1972 for Haryana India..The white patches in image are not cloud as there is no shadow associated with them. Please help in identifying these white regions..
Hi
I am not confirm... although I may wrong. But it seems snow cover. If it is the part of northern Haryana than it is quite possible that during 72s it may snow cover.
Thank you very much Ranjan Ji.. This image is of October month. This possibility of snow is nil because this is a flat plain area.
Of course Dharmendra sir you may right..as I had already mentioned that it may or not....but spectral characteristics looks quite similar to snow cover. I think some old researchers may help you who have done some work over this area.
Thanks
Avinash Ranjan
Of course it may be snow cover.
You can check this by date of acquisition and also there is written how much cloud cover is in the image.
You can overlay this image to the google earth to identify the white areas.
Hi!
It´s difficult to tell only with this capture, but I agree it could be snow or cloud cover. Did you check the image header for cloud cover? From my experience, there are not that many options to get that kind of reflectance.
regards
Hi Dharmendra
Also check the hour that the satelite pass for this area. Maybe their could be clouds but you don't see the shadow because it is midday.
Yes Maria.. you may be correct.. but the local pass time is around 10:30 AM and thus there is less chance to have a nadir view... can this be a salt affected land..???
Dear Dharmendra,
It may be more possibility to be Salt affected land. Because salty soil have always high reflectance. Another aspect is that Haryana have 15 percent saline area of the country, where Rewari and central hriyana have highly salin soil.
Thank you very much sir...I am also thinking in this direction.. but not able to get correct source of usar land..Please suggest if any.
In Indo-Gangetic Plains lot of soils are salt affected because of water logging and irrigation. Below ground salts get dissolved in water and move upwards due to soil surface evaporation/evapo-transpiration. These salts get deposited on surface and are white to brownish-white in colour. The lands appear in white on standard FCC.
