Remote Sensing and Geographical Information Svstems in EDidemioloPv. S. I. Hav. S. E. Randolnh &“D. J. Rogers ieditors). L&don: Academic Press, 2060. 357~~. Price E93.95 ISBN o-12-031747-8 (hardback), price E46.95 ISBN o-12-333560-4 (paperback). This book is the second of the occasional special volumes of Advances in Parasitology and has primary focus upon the methods of acquisition, techniques of interpretation and use of remote-sensing (RS) data to study vector-borne diseases. The appearance of this volume is timely, reflecting the current growing interest of many parasitologists in the use of these powerful and fascinating tools. The book is available in both hardback and paperback formats, the latter certainly more affordable but a little over-priced for its targeted audience, post-graduate level and above. The book is produced to the high standard associated with Advances and thoughtfully illustrated, including 18 colour plates. The past 20 years have seen many changes in RS. There is new computer hardware, better geographic information systems (GIS) software and greater scrutiny of the Earth from an ever-increasing number of orbiting satellites with a variety of onboard sensors. Indeed it has become a fast-moving arena of research spanning both physical and biological sciences. To the non-specialist, all this information can be a little bewildering to assemble and digest but this book provides a good tour through it. The 3 guest editors have organized the papers, each with

a comprehensive reference list, in this volume into 10 chapters that originate from over 20 contributors. The first 3 chapters provide a sound overview of principles and limitations of RS data acquisition, interpretation of RS data for land cover inference and commonly used spatial statistics and multivariate models in map projections. The collation of reference website addresses is particularly useful. The next 4 chapters assess progress of recent work on African trypanosomiasis, malaria, tick-borne diseases and human helminths. The caveat that ‘all models are wrong, but some are useful’ is sensibly applied throughout but it is astounding how RS and GIS provide greater insight into disease transmission, despite the often lack of coincident data. Similarly, the theme that RS does not intend to supplant other data sources is echoed; on the contrary, RS and GIS can revitalize existing disease data and emphasize the collection of more. The following 2 chapters look towards the future. Areas of further research are identified and disease-forecasting models are placed within the context of public health. The final chapter discusses the outreach, affordability and technology transfer of RS to countries of the developing world. A better forum between biological and physical scientists is a good thing. This seminal book goes some way to bridging the divide. J. R. Stothard Wolfon Wellcome Biomedical Laboratories Department of Zoology The Natural Histoy Museum London S W7 5BD, UK
