NDVI (Normalized difference vegetation index) Image of 1975 Landsat MSS Image
Identifier:238_1
Publication date:1975
Author(s):
William Stefanov
Abstract:
Normalized difference vegetation index (NDVI) produced from the 1975 Landsat MSS image. NDVI is a means of monitoring density and vigour of green vegetation growth using the spectral reflectivity of solar radiation.

Methods used in producing this dataset:
NDVI computation
The raw Landsat image was clipped to CAPLTER, georeferenced to NAD27 datum and UTM zone 12 coordinate system. Additional preprocessing include atmospheric correction and radiometric calibration. The model of the following form is then applied: (NIR-RED) / (NIR+RED), where NIR (Near Infra-Red) is the TM band 4 (0.76-0.9 micrometers) and RED is band 3 (0.78-0.82 micrometers). The range of possible values is -1 to +1.
