Method Research and Design of Full (Semi)-automatic Terrain Factor Intelligent Extraction

结合工作流思想,采用XML建模语言实现支撑全(半)自动地形因子智能提取模型的设计与过程描述。结合地形因子提取算子体系与模型,建立全(半)自动地形因子智能提取系统,并以地面起伏度提取为实验样例,通过流程组合、因子模型建立、参数配置、程序驱动执行等环节实现地形因子流程化、全(半)自动智能提取。系统解耦流程、算法以及专业软件对传统地形因子提取模式的捆绑,通过订制提取模型,灵活提取专题地形因子,提取效率、精度与扩展性较为理想。

Based on the idea of workflow, The paper used the XML modeling language to form terrain factors intelligent extraction model design and process description. The paper established full（semi） - automatic intelligent extraction system for terrain factor by combined with intelligent extraction model of terrain factor and Operator system. Building system realized the process execution and full（semi） -automatic terrain factors intelligent extraction through factor model ,parameter configuration,program driven execution by taking relief degree extraction as an example. Building system not only decoupled traditional binding of the terrain factor extraction pat- terns at the aspect of process,algorithm, professional software ,but also customized extraction model to conducted flexible extraction of thematic terrain factors and reach ideal effect in the extraction efficiency and precision.
