Research of sugarcane harvest process monitoring with multi-temporal HJ-1 satellite data

Guangxi Autonomous Region is the largest sugar production area in China, whose sugarcane planting area and sugar production account for about 60% of the country. Timely and accurately monitoring sugarcane planting and harvesting information is of great significance for sugarcane production. The multi-temporal HJ-1 A, B satellite CCD data were used to extract the sugarcane planting and harvesting information and area in Fusui county, Guangxi Autonomous Region. In this paper, We chose four temporal images from Nov.5th, 2009 to Feb 19th, 2010 and extracted the sugarcane information in each image, then overlaid the adjacent temporal sugarcane information and got the harvest area during the period. The research showed that: 1) The spatial resolution, waveband, radiation resolution of HJ-1 A, B satellite CCD data can meet the requirement of extracting main crop growth information and calculation area in complex land cover area at county scale and above; 2) The multi-temporal HJ-1 A, B satellite CCD data can be applied to monitoring the sugarcane harvest process and survey and statistic of agricultural resources which need high-temporal remote sense data.
