ABSTRACT
The traditional information communication mode is unable to adapt to the requirement for information gathering. On the basis of the geo-hazards survey on seven hundred counties in China, with each county as a unit, a Geo-Hazard Survey Information System was developed. This system gathers national geo-hazard survey information and provides the functions of statistical and analysis assessment. The Geo-Hazard Survey Information System, which is based on the survey and GIS platform, gathers national geo-hazard survey information and provides the functions of synthetical statistic and analysis assessment. Construction of the Geo-hazard Survey Information System is a complicated system engineering task, which is based on the geo-hazard survey data and applying information technology. The information technology relates to digital production technology, data quality control technology, spatial database technology, mass multi-map sheet data organization and management technology, data share and publishing technology.
