IMAGES TO MAP AND ESTIMATE SUGARCANE AREA IN THE STATE OF SAO PAULO: crop
year 2003/2004
Remote
sensing images present potential to map and estimate crop area. However,
its operational use is limited due to the low availability of cloud-free
images. The present work has the objective to map and estimate sugarcane
crop area in the state of Sao Paulo, Brazil, using Landsat images and image
classification and interpretation techniques. Images were acquired at four
dates during one year in order to identify the various growth and management
conditions of the sugarcane crop. Cultivated sugarcane area in 2003 was
3.09 million ha. Sugarcane area designated for harvesting in the crop year
2003/04 was 2.57 million ha. This work should continue in following years
to test the feasibility of the operational use of these images in order
to provide objective and predictive information on sugarcane area in the
state
