NDVI = (near infrared - red) / (near infrared + red) in raster calculator to get a unitless raster ranging from -1 to 1. This seems to line up with most online guides showing how to calculate NDVI.... The new Phantom MAPIR Drone is the only highly customizable Drone for Precision Farming which allows you to analyze and monitor health vegetation of your crops, generate orthomosaics, NDVI maps, yield maps, point clouds, 3D Models, Contour Lines and much more.

  • The MODIS instrument is operating on both the Terra and Aqua spacecraft. It has a viewing swath width of 2,330 km and views the entire surface of the Earth every one to two days. Its detectors measure 36 spectral bands between 0.405 and 14.385 µm, and it acquires data at three spatial resolutions -- 250m, 500m, and 1,000m.
  • Optimized image formats—Some imagery can be slower to read than others due to their storage format or compression, and it is recommended that you convert these into more optimal formats.
