讨论了基于互联网的地理信息组织与处理，提出一种分布式的跨平台的地理信息组织与处理方法，并讨论了它的软件实现。最后介绍根据这个思想设计的基于互联网的地理信息系统软件原型，以实例说明这种方法的可行性和优越性。

The new generation of GIS demands the integrated management of vector, image and DEM data. This paper brings forward a vector, image and DEM integrated spatial data model on the basis of the object-oriented idea. It also discusses the implementation method of this integrated spatial database management system. The spatial database management system has been used in the construction of China Spatial Data Infrastructure as the base of a GIS software, GeoStar. It reveals that the system has high efficiency and feasibility to manage national, provincial and city spatial data of multi-scales and multi-sources.

介绍了新一代面向对象的GIS基础软件系统吉奥之星NT版的总体设计思想、系统结构、功能特点和有关关键技术。

以矿山地质为背景，深入分析三维空间信息系统所涉及到的空间对象以及它们之间的联系，提出了几种新的空间对象类型。探讨用矢量与栅格混合的数据结构，以及面向对象的数据模型来表达各类三维空间对象，以此作为设计和建立三维地理信息系统的基础。

Taking geological exploration engineering as the topic of our research, we presented a hybrid data model integrating vector and raster data, and proposed a sub-model; i.e., a QTPV (Quasi Tri-Prism Volume) model. Based on QTPV, the concept model, logical model and data structure were designed in detail. Modeling, model cutting and partition algorithms on QTPV are proposed. The modeling features of QTPV have been discussed. The QTPV model is more efficient than 3D FDS and TEN in terms of partition, storage volume, modeling ability, and application in Geological Exploration Engineering (GEE). A 3DgeoMV system prototype has been developed based on the proposed QTPV model. A case study has been conducted by using the real borehole sample data from a GEE area in China's Inner Mongolia China. The application shows that the QTPV has the ability to model real 3D in GEE.
