摘要
以田野考古发掘中的各种三维空间对象为研究背景,进行详细的数据对象分类与描述.基于面向对象的思想,在进行田野考古三维现象剖析的基础上提出了适合考古发掘对象的矢量与栅格集成的混合数据模型,并以地层模型和地物模型分别加以描述和建模,论述了建模方法,即结合地层数据源类型,进行基于多层DEM与QTPV的地层建模,同时根据地物类别、形状和内部堆积进行基于TIN与TEN表示的三维地物建模,并提出了两者的集成方法和实施步骤.研究结果实现了田野考古GIS空间数据模型的统一表达,为田野考古GIS的开发提供了模型支持和基础.
Based on the object-oriented approach and the three-dimensional spatial phenomena in field archaeology GIS (FAGIS) as the research objects, the spatial objects were analyzed, and the hybrid 3D spatial data model with integrated vector and raster was put forward. Besides, the field archaeology model was divided into the stratum model and geographical object model, and then the two models were designed and expounded, including 3D stratum modeling based on DEMs and QTPV by stratum data resource, and 3D geographical objects modeling based on TIN and TEN by the sorts and figures and inner filling of the objects. The integration method and steps of the stratum model and geographical object model and modeling method also were discussed and completed, which implemented the unification of data model of FAGIS and becomes the basis of FAGIS.
