GIS application in cropping system analysis - case studies in Asia: proceedings of the International Workshop on Harmonization of Databases for GIS Analysis of Cropping Systems in the Asia Region, International Crops Research Institute for the Semi-Arid Tropics, Andhra Pradesh, India, 18-29 Aug 1997

This publication provides an overview of GIS software and is supplemented with Asian case studies. Participants from Bangladesh, India, Nepal and Sri Lanka had hands-on training in different GIS software and the relevant features of each case study are presented. Data sets on rice-wheat and legumes were assembled in the GIS core and were analysed using various GIS tools. Analysis using 'overlay', 'reclassification' and statistical analysis were major applications. Case studies showed temporal and spatial changes in crop productivity and pests. A few studies attempted thematic mapping for constraints analysis.
