Method for realizing river water quality dynamic distribution based on GIS technology

The invention discloses a method for realizing river water quality dynamic distribution based on a GIS technology. The method comprises the following steps: data acquisition, spatialization processing, objectification processing, layer data superposition, layer data classification, event table construction and assignment, dynamic segmentation and rendering, and finally obtaining of a rendering graph reflecting river water quality dynamic distribution. Under the condition of limited water environment monitoring data, dynamic linear reference segmentation and assignment of the river are realized, so that multi-stage seamless dynamic rendering is performed on the basis of not interrupting the river, and full-flow automatic updating and processing are supported. 本发明公开了一种基于GIS技术实现河流水质动态分布的方法，该方法包括：数据采集，空间化处理，对象化处理，图层数据叠加，图层数据分类，事件表的构建和赋值，动态分段和渲染，最终得到反映河流水质动态分布的渲染图。本发明在水环境监测数据有限的情况下，实现河流动态的线性参考分割和赋值，从而在不需要打断河流的基础上，进行多级无缝动态渲染，并支持全流程自动化更新和处理。
