Abstract: In order to solve some problems in managing and parallel processing of global expanding remote sensing data, introduces the spatial subdivision organization framework. Firstly, analyzes the spatial properties of subdivision cell and its significant advantages in parallel processing. Then, discusses subdivision template and template parallel processing mode for remote sensing image. And a template-based parallel processing flow of subdivision remote sensing image is proposed. The special application example is carried out to extract crop planting area. The initial experiment of extracting wheat planting area in Xuchang shows: compared to the common ERDAS or ENVI software, this method can improve the extraction accuracy and processing speed to some extent.


Keywords: Spatial subdivision organization, Remote sensing image, Subdivision template, Parallel processing, Planting area extraction.
