New Proposals for the monitoring of Water Resources (Smartwater)

摘要

The objective of this study is to detect drought changes through the use of normalized difference drought index NDDI. It is applied to Urmia Lake and the data is downloaded from the Landsat 8 satellite with its sensor OLI/TIRS. Therefore, for a local analysis it can be thought as data with greater spatial resolution, as Landsat. The traditional spectral indices, such as a the NDVI, NDWI were utilized to calculate spectral index NDDI; Urmia Lake-Iran was chosen as a study area using a set of multiband scenes from the years (2013 - 2016) of Landsat 8 OLI/TIRS, with the purpose of obtaining maps of drought and thus faciliting an analysis of research that can add to the decision-making and implement plans of action.
