Model of Field-based Spatial Dynamic Data and Design of Spatial Dynamic Modeling Language
Ma Xiu · Geography and Territorial Research · 2000
Current study on Spatial Database Management Systems is mainly focused on object-based spatial data model. However, existing and emerging applications require new functionalities to support field-based data, especially considering the need of spatial dynamic simulation. The objective of this paper is to design a spatial dynamic modeling language, which can be embedded in the GIS so as to provide the support to simulate complex space-time processes for database management and algorithm optimization. The language can also provide a clear logic diagram for building a spatial dynamic model and a quantitative and simulated tool for management of natural resources, environmental and ecological application.
