Lines and Polygons Overlay Analysis (LP-OA) is an important analysis method that has been widely used in geographic information systems (GIS). In this study, a new algorithm, Uniform Spatial Grid Indexing (USGI), is proposed to study LP-OA. By applying this method, the theoretical position is evaluated and the theoretical results are verified, suggesting that this algorithm can contribute to the software...
In this paper, we have proposed a new Image-based Multi-scale Subdivisional Expression Model (IMSEM) based on Global Subdivision Gird (GSG). It creates a new approach that enables the common man using image itself to express geographic objects, rather than overlying a vector layer. To demonstrate this approach, the Geosubdivision System has been developed which shows that the IMSEM can express geographic...
Remote sensing images have been widely used in various fields, how to process remote sensing images in real-time has become an important problem. Based on Global Subdivision Model (GSM), this paper presented a framework of a parallel computing system of remote sensing images (GSPCS). GSPCS consists of management nodes, storage nodes and computing nodes. In GSPCS, in order to load image data that need...
With the rapid development of remote sensing technologies, the amount of the remote sensing image data is increasing dramatically. However, the remote sensing image data's usage rate still remains very low. To solve this problem, we propose a new Service model: Anytime-Anywhere Service (AAService) model, under which users can get remote sensing images anytime and anywhere. Then we implemented and...
