Abstract:

We built a file catalog system of data application based on the partwhole ontology of spatial relation to manage the massive remotely sensed image files effectively. Firstly we analyzed the property of images’ metadata and calculated the weight for application. Secondly, we built the concept level relation, and calculated the similitude degree of the image property to build the catalog tree. Thirdly, we stored the files into the corresponding directories. Finally we designed and realized the directory experiment system. Experimental results show that our method is effective for image data’s high efficient integrative management.
