Abstract

The invention provides a geographic information system (GIS) information ultrahigh resolution displaying method. The method is a splicing displaying method which includes acquiring GIS map information through cluster map sub blocks and WMS service in parallel on the basis of the computer cluster parallel processing, utilizing map projection transformation distribution to process data and conducting parallel texture rendering displaying through a graphic processing unit (GPU). A computer cluster is utilized to acquire, process and display map information, and the massive GIS map processing and displaying problem can be effectively solved. According to a cluster map sub block technology, sub block processing is conducted on a high resolution map according to cluster node machines, the resolution of the displayed map can be expanded by increasing the number of the node machines and is not limited by the resolution of a display screen, and ultrahigh resolution GIS information displaying can be achieved.

Description

technical field [0001] The invention relates to a GIS (Geographic Information System or Geo-Information system) map display technology, in particular to a super-high-resolution display method for massive GIS information. Background technique [0002] In recent years, my country's GIS information construction has developed rapidly, and it has been widely used in transportation, military public security, land management, urban management, disaster prevention and mitigation, resource investigation, water conservancy and electricity, agriculture, forestry, animal husbandry, and lifeline project management. With the rapid development of satellite technology, the development of GIS systems based on specific systems and specific environments has become a research hotspot in the industry. GIS spatial data has the characteristics of large data volume, various forms, and complex structure. In order to better utilize the spatial visualization advantages of GIS information and realize t...
