最近在多哥开发了一个基于栅格或网格的地理信息系统，其中包含采采、锥虫病、动物生产、农业和土地利用方面的数据。本文描述了全区域数字采采蝇分布图和丰度图的生成，以及这些图如何与当地气候和农业生态环境相一致。结果包括：(1)基于季节气象数据和美国国家海洋和大气局（NOAA） AVHRR和METEOSAT变量的时间序列，建立了生态差异区域的空间分异图；(2)Glossina tachinoides Westwood、palpalis palpalis （Robineau-Desvoidy）、G. morsitans submorsitans Newstead、G. longipalpis Wiedemann、G. medicorum Austen和G. fusca fusca （Walker）采采蝇分布图；（iii）采采蝇丰度图或“风险”图，根据数据库内的季节性波动进行校正。结论是，基于网格的采样是快速评估任何国家或区域内当前病媒和疾病状况的理想方法，遥感在规划这种采样系统方面可发挥重要作用。
A raster or grid-based Geographic Information System with data on tsetse, trypanosomosis, animal production, agriculture and land use has recently been developed in Togo. This paper describes the generation of area-wide digital tsetse distribution and abundance maps and how these accord with the local climatic and agro-ecological setting. Results include: (i) a spatial demarcation of ecologically distinct areas, producing a seasonal cluster map based on seasonal weather data and temporal series of satellite derived National Oceanic and Atmospheric Administration (NOAA) AVHRR and METEOSAT variables: (ii) tsetse distribution maps of Glossina tachinoides Westwood, G. palpalis palpalis (Robineau-Desvoidy), G. morsitans submorsitans Newstead, G. longipalpis Wiedemann, G. medicorum Austen and G. fusca fusca (Walker); and (iii) tsetse abundance or 'risk' maps, corrected for within database seasonal fluctuations, for G. tachinoides and G. p. palpalis. It is concluded that grid-based sampling is the ideal method for rapid assessment of the current vector and disease situation within any country or region, and that remote sensing has an important role to play in planning such a sampling system.
