TAHDEED is a desktop application for modeling hotspots of vector-borne diseases, and spatio-temporal risks of the diseases based on the locations of diseases and their vectors.  These models can used to assess the association between cases, vectors and different environmental, meteorological and socioeconomic variables in a geographic information system (GIS) environment. These models can be used to predict future disease movements and trends, which can help in preparing a plan for controlling and managing them. The software can be used by GIS and non GIS users in different health and environmental agencies.
