地理空间数据相似度计算软件(GDSCS V1.0)
收藏资源简介:
地理空间数据相似度计算对于地理空间数据的智能推荐和查重等具有重要意义。为了有效提升地理空间数据相似度的计算精度和效率,作者团队在综合分析现有各类方法优缺点基础上,提出了一种集成文件信息、元数据、数据实体三个层次的地理空间数据相似度计算方法,并将该方法实现于地理空间数据相似度计算软件(GDSCS V1.0)。该软件基于Windows 10平台PyCharm软件研发,包含了三个模块的计算功能:文本相似度、栅格数据相似度和矢量数据相似度。目前版本包括中文版和英文版,对输入数据限定元数据支持.json格式,数据实体支持GeoTIFF(.tif)和Shapefile(.shp)格式。
Geospatial data similarity calculation is of great significance for intelligent recommendation, duplicate checking and other applications of geospatial data. To effectively improve the accuracy and efficiency of geospatial data similarity calculation, the research team, based on a comprehensive analysis of the advantages and disadvantages of existing various methods, proposes a geospatial data similarity calculation method that integrates three levels: file information, metadata, and data entity, and implements this method in the geospatial data similarity calculation software (GDSCS V1.0). This software was developed using PyCharm on the Windows 10 platform, and includes three calculation modules: text similarity, raster data similarity, and vector data similarity. The current version is available in both Chinese and English versions, with the requirement that metadata supports JSON format for input data, and data entities support GeoTIFF (.tif) and Shapefile (.shp) formats.
