基于夜间灯光数据的郑州市用地扩展特征分析

The Characteristics Analysis of Zhengzhou Urban Land Expansion Based on Night-time Light Data

    摘要
  • 摘要: 针对城市用地空间扩展难以高精度量化分析的问题,提出了一种融合夜间灯光数据、 遥感影像和在线高清瓦片地图服务的量化分析方法.基于美国国防气象卫星( DM S P )的可见红外成像线性扫描业务系统( O L S )、L a n d s a tTM和天地图在线地图,设计了夜间灯光数据中断值的精确判断方法,综合分析城市用地的扩展模式.以郑州市为例,详细介绍了不同类型扩展特征的提取方法.采用C#和A r c E n g i n e开发了一个夜间灯光G I S原型系统.结果表明, 2 0 0 8年到2 0 1 3年郑州市城市用地的拓展类型主要以外延型和增强型为主,所述方法精度更高,采用原型系统处理较为便捷.

     

    Abstract: The precise analysis of city land expansion is one of the current hot issues in GIS. A method for considering the night-time light data, remote sensing images and online HD Tile Map Service was proposed. Based on US Defense Meteorological Satellite (DMSP) data, Landsat TM and online tile map of Tianditu, it was described how to get the break value of the night light data. Taking Zhengzhou as an example, the method of extracting different expansion types was introduced in detail. A prototype system of nighttime light were designed and developed with related developed tools include VS C# 2012, Arc Engine 10.2 and DotNetBar 2.0. The results showed that the main type of Zhengzhou urban land expansion belonged to the extension and enhanced type. The accuracy of the method was high and the prototype system was convenient.
