Abstract

More spatial resolution it not the necessarily better and spatial resolution is not the only measure of resolution that matters for crop monitoring. Temporal resolution is important if the target can change quickly as crops can, and perceptual resolution of the color axes of the display is important. Satellite data can be displayed as color images for operational crop monitoring. The atmospheric effects on radiation detected by the satellite, and rapid changes in the target crop make quantitative analysis impractical. This leaves qualtitative analysis of information displayed as color patterns within the images. A system is presented for displaying changes in intensity, hue and saturation (IHS) which is optimally suited for visual (qualitative) analysis. The color images use an IHS system to represent changes in crop health. Crops are monitored by comparing images and their patterns throughout the growing season. The system has been used successfully for monitoring the Sahel region of Africa, and is being tested for Southeast Asia.
