Project and Training Dates

Remote Sensing for Monitoring Malaria in Kenya
October - November 1997

Objectives of visit:

  1. Acquire an understanding of the basic principles of remote sensing and image processing
  2. Evaluate remote sensing data and methodologies as an efficient, modern tool for affecting strategies in control of vector borne disease. The focus is on malaria in Kenya.

Accomplishments

Training activities used TM data of California because no imagery for Kenya was readily available to work with. Image rectification and both supervised and unsupervised classification were performed on data covering the Central Valley (see M. Bagayoko report for more details).

There was an interest in performing a time series analysis because the work in Kenya is to investigate the relationship between the malaria vector and environmental change and the resurgence and outbreak of highland malaria in western parts of Kenya. TM images for 1983 and 1993 of the San Francisco Bay Area were compared to derive a thematic map showing landcover changes for this region. Different types of change detection methods were used; image ratioing and principal components analysis employed.

Future Plans

Mr. Ogino plans to establish a closer collaborative link between the International Center for Insect Physiology and Ecology and CHAART at the Ames Research Center. He is working to acquire Erdas Image image processing system to equip the spatial analysis lab. Research plans include integrating remote sensing into a tsetse fly prediction model over the Rift Valley region of Kenya and to include remote sensing in a database of East, Central and South African regions for the Malaria Vector Control program.
