基于GIS二次开发的矿山地质评价系统设计

Design of Mine Geological Evaluation System Based on GIS Secondary Development

矿山地质评价在矿业开发中占据重要地位,基于GIS二次开发设计矿山地质评价系统,是促进矿山的科学化、集约化开发的必由之路。系统设计为数据层、服务层、表现层组成的C/S架构,采用可编程逻辑控制器与手持GPS设备设计系统硬件,系统软件上,基于栅格数据设计GIS空间分析功能,基于正射纠正、影像分割技术设计遥感影像处理功能,基于GIS二次开发技术和层次分析法设计地质评价功能。系统实例测试结果表明,本文设计系统实现了矿山地质评价,且具有较高的评价精度。

Mine geological evaluation occupies an important position in mining development.Based on GIS secondary development,it is the only way to promote the scientific and intensive development of mines.The system is designed as C/S architecture composed of data layer,service layer and performance layer,programmable logic controller and handheld GPS equipment design system hardware,system software,GIS space analysis function based on grid data design,remote sensing image processing function based on ortho correction and image segmentation technology,and geological evaluation function based on GIS secondary development technology and hierarchical analysis method.The results show that the mine geological evaluation can have high evaluation accuracy.
