[PDF][PDF] Drought estimation maps by means of multidate Landsat fused images
D Renza, E Martinez, A Arquero… - Proceedings of the 30th …, 2010 - academia.edu
The purpose of this paper is to analyze the usefulness of traditional indexes, such as NDVI
and NDWI along with a recently proposed index (NDDI) using merged data for multiple
dates, with the aim of obtaining drought data to facilitate the analysis for government
premises. In this study we have used Landsat 7 ETM+ data for the month of June (2001-
2009), which merged to get bands with twice the resolution. The three previous indices were
calculated from these new bands, getting in turn drought maps that can enhance the …
