Research and Implementation of WebGIS Data Efficient Transmission Technology
Abstract: There are many factors that affect the transmission performance of WebGIS, the network transmission delay of GIS data increases considerably especially when the network bandwidth is low or the number of service requests is more. For GML map format, this paper proposes a data-driven classified GML compression CGDC (classified GML data com-pression) which distinguishes the structural data and value data, verifies its effectiveness. For raster data, according to the data size, it verifies how to use tile-based technology to improve data transmission efficiency by experiment.
