OGC-compatible high-performance web map service for remote sensing data visualization

Web Map Service(WMS) is an Open Geospatial Consortium (OGC) data visualization service used for requesting and producing maps on the internet. OGC WMS has been widely adopted in the Geographic Information System (GIS) community. These WMSs make remote sensing data available to a wider range of public users than ever before. However, the performance of current WMS servers can not satisfy the need of massive remote sensing data visualization. To implement a performance-optimized WMS server, we propose a global remote sensing data hierarchical model based on image pyramid and tiling techniques for data organization. On this basis, we implement an OGC compatible tiled WMS service and a service wrapper for mapping WMSs to Web Services. Finally, we evaluate the tiled WMS server using real remote sensing datasets. Experiment results demonstrate a high-performance data access.
