Consistent handling approach on multi-temporal land use status data with various differences

摘要

This study aimed to reduce and eliminate the differences among the multi-temporal land use status data,to derive the multi-temporal land use status data series that can be mutually compatible and coordinated,and to support and promote the comprehensive analysis and assessment based on the multi-temporal land use status data.In this study,based on the analysis and investigation of the existing real multi-temporal land use status data,we firstly more comprehensively summarized and described the types of differences and the forms of expression among the multi-temporal land use status data sets,then we proposed the uniformity treatment methods for the treatment of data differences based on Feature Manipulate Engine (FME) software,elaborated the basic steps and the related principles of this method and conducted preliminary experimental verification.
