Abstract

A system and a method for multivariate conversion of a survey and map results catalogue are disclosed. A system and a method for multivariate conversion of a survey and map catalogue are analyzed, anda method for multivariate conversion of a survey and map catalogue in a Shapefile format of multi-type and multi-scale of an analog topographic map is formed, such as survey control point, vector mapdata, digital elevation model data, digital raster map data, image data and so on. The mapping rules from metadata of surveying and mapping results to multi-conversion model of surveying and mappingresults catalogue are established, and the mapping relationship between attribute information and spatial information of multi-conversion method of each type of surveying and mapping results metadataand surveying and mapping results catalogue is clarified. Based on the mapping rules, the mapping results metadata entity files are loaded in batches by the conversion tool, and the conversion tool automatically identifies the correlation of mapping results metadata--mapping rules--surveying and mapping results directory multi-conversion model, so automatic, fast and batch conversion is completed.

Description

technical field [0001] The invention relates to the technical field of spatial information processing, and in particular to a system and method for multiple conversion of surveying and mapping results catalogs. Background technique [0002] The catalog of surveying and mapping results is the result of combing and integrating surveying and mapping results resources, which can effectively promote the sharing and application of surveying and mapping results resources. At present, the main source of the catalog of surveying and mapping results is the metadata of surveying and mapping results. The surveying and mapping results have characteristics such as multi-scale, multi-type, and multi-source, which directly lead to the fact that the metadata of surveying and mapping results also has various types of results, inconsistent attribute information structures, multi-sources, and diversity. This has brought great difficulties to the publication and sharing of the catalog of surveyi...
