Therefore you will need to make sure your imagery has been converted to express reflectance. The equation to calculate NDVI is as follows:.
The resulting NDVI will have values ranging from -1 to 1, where high positive values represent healthy green vegetation. You can see the tree I selected with the cross hairs displays a pixel value of 0. Here you can see the pixel values range from From an ecological perspective, this makes sense given the sparse vegetation within the semiarid desert this NDVI is derived from.
You need to look at the sensor specifications and select the correct bands for NDVI. It would help tremendously if you took the time to read a few basic articles on NDVI and research your sensor so you can make better informed decisions on erdss analysis.
