| Abstract: | Reliability is one of the most important theoretical problems in geographical conditions monitoring. In this paper, it presented that the research on the reliability of geographical conditions monitoring was based on the theory of spatial data reliability. First, it reviewed and analyzed the theory of spatial data reliability. The scope of reliability of geographical conditions monitoring data is defined. Secondly, it proposed the framework of the reliability evaluation of the monitoring data, and it identified the contents, indicators, and process of the reliability evaluation correspondingly. Then, it introduced the application of the above theoretical results on overall reliability evaluation of the resultant data from the First National Geographical Survey. Finally, some prospects for future research on the reliability of geospatial data were given. |
