The normalized difference vegetation index (NDVI) is a simple graphical indicator that can be used to analyze remote sensing measurements, typically but not necessarily from a space platform, and assess whether the target being observed contains live green vegetation or not.Contents.he normalized difference vegetation index (NDVI) is a simple graphical indicator that can be used to analyze remote sensing measurements, typically but not necessarily from a space platform, and assess whether the target being observed contains live green vegetation or not.

1. DVI-D is a DVI connector that is meant for digital signals only while DVI-I is a connector that allows both digital and analog signals.2. DVI-I connectors have all the necessary pins for a single link DVI cable while DVI-D connectors lack the four pins that is supposed to carry the analog signal.3. The long and flat pin on the DVI-D connector is slightly smaller than that on the DVI-I connector. 4..
