Comparison of NDVI, NDRE, MSAVI and NDSI Indices for Early Diagnosis of Crop Problems

Agricultural Engineering, 2023
Abstract In precision agriculture, it is possible to use satellite monitoring of fields. Satellite monitoring systems allow you to get free images with a resolution of up to 10 m per pixel, which is sufficient to determine the state of vegetation of plants on such indicators as the normalized vegetation index NDVI.

Prototype land-cover mapping of the Huascara´n Biosphere Reserve (Peru) using a digital elevation model, and the NDSI and NDVI indices

Journal of Applied Remote Sensing, 2009
On the basis of Landsat 7 ETM+ imagery, a prototype land-cover map was prepared for the Huascaran Biosphere Reserve (Peru). This document should contribute to the sustainable management of the Huascaran Biosphere Reserve, while making it possible to establish a regional planning policy and to prepare a natural risks map, which is still lacking in the ...
