Creation of a Composite Drought Index Using ArcGIS and Satellite Data
Track: Atmosphere, Climate, and Weather
Authors: Calvin C Poulsen
The goal of the project was to develop a Composite Drought Index (CDI) using existing data sources and tools. Extensive research indicated that the best choice would be a grid base approach with remotely sensed inputs. ArcGIS and its extensions were used to resample and extract indicator values from the massive raw data sets and then to calculate the CDI values. ArcGIS was also used to generate dataset from the CID values as well as to visualize these data sets.
