Abstract
Summary This paper suggests a structure design of drought risk assessment and mapping technology and a 6-stage implementation process regarding the country specifics of Ukraine. “Stage-to-stage” implementation process involves collection of observational data for drought assessment (both field measurements and satellite data), data pre-processing, formulation of methodology for drought assessment, assessment of drought and mapping. The final stage of technology seeks next technical procedure with DI spatial database like spatial DI interpolation, visualizing resulting DI maps, publicly available DI maps publication. The creation of risk maps requires Geographical Information Systems (GIS) software. To carry out it, the spatial data analysis can be used for next GIS software: MapInfo, ERDAS, Intergraph, IDRISI, GRAM, ArcInfo, GRASS, AutoCAD maps etc. For the mapping of drought, the most widely used ArcGIS in Ukraine, developed by the Institute for Environmental Systems Research (ESRI), can be recommended. ArcGIS offers a unique set of capabilities for applying location-based analytics to drought mapping, contextual tools to visualize and analyse ground based and satellite data. It includes imagery tools and workflows for visualization and analysis, and access to the world’s largest imagery collection.
