Update on a system for large area crop inventory from remotely sensed data

In connection with the conduction of the Large Area Crop Inventory Experiment (LACIE), a state-of-the-art technology for the inventory of crops using satellite data was developed and tested over a period of three years (1975-77). A method was obtained for determining the total wheat production in a given region by looking at only a subset of its area. The present investigation is concerned with the current state of the art as obtained in the aggregation technology of the Agriculture and Resources Inventory Surveys Through Aerospace Remote Sensing (AgRISTARS) program. Attention is given to details of AgRISTARS baseline aggregation technology, and to recent improvements and future research directions.
