USING THIRD PARTY DATA TO UPDATE A REFERENCE DATASET IN A QUALITY EVALUATION SERVICE
data update quality assessment geospatial database conflation web service
2016/11/8
Nowadays it is easy to find many data sources for various regions around the globe. In this 'data overload' scenario there are few, if any, information available about the quality of these data source...
Dom Quality Evaluation Based on Multi-Level Fuzzy Comprehensive Assessment of Entropy Weights
GIS Analysis Sampling Image Quality Entropy Weight
2015/12/18
With the development of RS technology, the evaluation of DOM becomes more important. Multi-level fuzzy comprehensive evaluation is the traditional method for DOM evaluation. But in the process of trad...
