What is layerstack? Layer stacking is a process of combining multiple separate bands in order to produce a new multi band image. This type of multi band images are useful in visualizing and identifying the available Land Use Land Cover classes. In order to layer-stack, multiple image bands should have same extent (no. of rows and columns). How many bands should be stacked? Mostly satellite images comes in a zipped folder of multiple bands like 11 or 13. In order to save the

The Indian Space Research Organisation (ISRO) is planning to study Venus from an elliptical orbit that is closest to the planet at 500 km and 60,000 km at the farthest end – similar to Mars Orbiter Mission (MOM) of 2013. Shukrayaan-1 (Venus craft) is a proposed orbiter to Venus by the Indian Space Research Organisation (ISRO) to study the surface and atmosphere of Venus. Earmarked for mid-2023, the mission, tentatively named ‘Mission Venus’, has revived the 18-month-old pitch
