摘要
根据GIS空间数据包含的信息:①空间定位数据;②属性数据;③空间图元信息。把数据检索进行重新分为空间检索、属性检索和空间图元参数检索等3类,并利用Visual basic6.0+Map GIS6.5二次开发函数库设计和开发出图元参数条件查询模块。该模块是空间检索和属性检索的有益的补充,且界面友好,可以有效地通过空间实体的图元参数进行数据检索,并应用于西藏冈底斯斑岩铜矿预测评价中,成功地通过图元参数检索提取了岩浆岩、断裂构造等有用信息。
As space positioning data, attribute data and spatial element parameter information are included in GIS spatial data, three-category data query modes are re-divided, they are spatial query, attribute query and spatial element parameter query. And then the authors have designed and developed a spatial element parameter query model based on visual basic 6.0 and MapGIS 6.5 second development kit. The spatial element parameter query model can successfully analyses and extract information through spatial element parameter. This model has been used in porphyry copper deposit prediction in Tibet and verified efficiently.
