综合地质空间数据管理及其组件开发

General Geological Spatial Database Management and Component Development

针对地质数据种类繁多、数量庞大、数据格式复杂等特点,将这些数据从表现形式上抽象为图件、文档、表格、报告以及分类五种类型。通过转换将文档和表格类型数据以BLOB格式或文件索引格式导入到Oracle数据库中;通过预处理将矢量数据以及遥感影像等栅格数据与综合地质数据库关联。并设计和开发了综合地质空间数据管理组件GeodbSM,实现了对地质空间数据的管理、查看以及信息查询等功能。

According to the characters,such as various types,numerous data amount and complex data formats etc.,geology data are divided into five categories,including map,file,table,report and classification.File and table data are converted into BLOB or file index before importing into Oracle database.Vector data and remote sensing images as raster data are connected with integrated geological database after preprocessing.Moreover,GeodbSM,the integrated geological spatial data management component,is designed and developed, which is used for geological spatial data managing, browsing and information query.
