Abstract:
Digital technology is moving rapidly to distributed computing. It is now possible for parts of a database to be stored and maintained at different locations for users to take advantage of economical or specialized processing at remote sites. On the other hand, over the next ten years, the complexity of geospatial databases will grow significantly through the use of commercial satellites, and ... space-borne and airborne multiple sensors. Integrated management and processing of hybrid data sets, i.e., vector maps and raster images, becomes an emerging issue.
Internet-based geoprocessing of hybrid spatial data in this context means efficient management, transmission and fusion of raster and vector data over the Internet. Due to (a) lack of knowledge to the integrated management of hybrid geospatial datasets; (b) lack of knowledge on the transmission of hybrid data sets through the bandwidth-limited Internet; and (c) very limited knowledge on the processing of hybrid datasets over the Internet, the objective of this research aims at the development of Internet-based geoprocessing approaches to handle hybrid data in an efficient and effective manner under distributed computing environments.
The focuses of the research will be placed on the following tasks:
1. Investigate the spatial data models under distributed computing environments to support hybrid data management and access.
2. Develop methods for the efficient use of bandwidth in transmitting large volumes of hybrid data over the Internet, including vector-based map generalization and raster-based image compression techniques; Develop Internet enabled methods for the fusion of hybrid data sets, including image-to-map matching, map-to-map conflation, and image-to-image fusion.
3. Develop Internet enabled methods for the fusion of hybrid data sets, including image-to-map matching, map-to-map conflation, and image-to-image fusion.
