NDVI-processed imagery using Landsat 8 OLI data from June 1 to November 31, 2021. Showing Punakha, Bhutan, vegetative areas are represented by green while black depicts non-vegetative areas. Bhutan is located in the Himalayas with altitude ranging from 550 ft. to 23,000 ft., resulting in vast diversity of both ecosystem and agricultural products. Examining vegetation area help in developing a crop mask and remotely sensed data collection protocol for rice in Bhutan.

The satellite imagery is a Sentinel-1 Ground Range Detection C-SAR image from July 2nd, 2021, taken over the Sudd Wetland located in South Sudan. The image shows the 'VV' backscatter values, which correlate to vertical transmission and vertical reception from the C-SAR instrument and are used to classify wetland inundation extent. Low 'VV' values (blue) represent areas covered by open waters & inundated land areas and high 'VV' values (yellow) represent dry land areas.
