Role of geographic information system in malaria control.
In this paper we provide an account of our experience in the application of remote sensing (RS) and geographic information system (GIS) in understanding malaria transmission dynamics at the local level. Two studies have been briefly reviewed. One is the application of RS on the mosquito production in the Sanjay lake and surrounding areas in Delhi. Studies are demonstrated that remote sensing data were useful in assessing relative mosquito abundance from large water bodies. The second study was carried out in Nadiad taluka, Kheda district, Gujarat on the application of RS and GIS in a village-wise analysis of receptivity and vulnerability to malaria. For this study, remote sensed data and topo sheets of 1:50,000 and 1:125,000 were used in preparing thematic maps. Digitised overlaid maps were subjected to computer analysis using ARC/INFO 3.1 software. Malaria annual parasite incidence (API) showed relationship with water table followed by soil type, irrigation and water quality, other parameters also contributed to malaria receptivity but less significantly. Based on GIS analysis location specific malaria control strategy was suggested to achieve cost effective control of malaria on a sustainable basis.
