The Characteristics Analysis of Zhengzhou Urban Land Expansion Based on Night-time Light Data
摘要
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 de-signed 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 en-hanced type.The accuracy of the method was high and the prototype system was convenient.关键词
