With the development of earth observation technology, various countries have established data systems, such as NASA, has established ECHO MODIS data system, NOAA has established CLASS data system, USGS has established the LANDSAT data system, INPE (Brazilian Space Information Bureau) has established the CBERS2 data system. The access protocols of these data system differ, while different access protocols...
Web feature service is an important part of geospatial data interoperability and enables GIS data with different formats to be operated at feature-level. Open Geospatial Consortium (OGC) has already developed standard implementation specifications for Web feature service, and for those Web feature services with different versions, such as WFS1.1, WFS1.0. OGC also define different schemas. Different...
Because the advances in research technologies and the geospatial data with which they deal are diverse and complex. The OGC Web Processing Service (WPS) has several areas of complexity. Basic request-response mechanisms need to contend with delays/failures, especially for mid-term or long-term actions. The asynchronicity in communication between a user and the corresponding Web processing service,...
Recent advances in sensor web geospatial data capture, such as high resolution satellite images as well as corresponding web ready data processing and modeling technologies, have led to the generation of large amounts of datasets on real-time or near realtime observation and measurement. The quality of observation data register has become a 'bottleneck' of sensor web-based applications. In order to...
