ArcGIS Exercise: Dengue Outbreak Analysis Using Spatial Statistics


Approximately 100 minutes

Course Description:

The course "Dengue Outbreak Analysis Using Spatial Statistics" is designed to give you a basic understanding of how to apply ArcGIS geographic information system tools to analyze and map the geographic and temporal distribution of dengue-positive households and mosquito trap counts relative to other population and environmental datasets in order to monitor, quantify, and understand the spatial diffusion of the disease and its vectors during a Dengue outbreak scenario. It is an exercise in tutorial format, with step-by-step instructions utilizing data for the island of O`ahu.

It requires access to ArcGIS ArcInfo version 9.1, 9.2, or later, and the Spatial Analyst extension. Evaluation copies of the software are available at the ESRI. Click here.

  2. Combine GIS overlay, statistics, and table join operations to measure and map the frequency of disease occurrences by Census units
  3. Use GIS spatial analyst tools to map the spatial density of disease occurrences
  4. Apply GIS tools to map disease vector counts over time and use spatial statistics tools to identify and map spatial clusters (hotspots) of disease vectors
  5. Apply spatial statistics tools to quantify and map geographic distributions and directional trends of disease occurrences over time and relative to other population and environmental datasets
