基于卫星影像整合公开资料生产数字线划图方法的研究

Research on DLG Production Method Based on Satellite Images to Integrate Public Information

随着科技的进步,目前卫星影像成果的精度已经可以满足一些特定比例尺地形图的生产要求。互联网作为公共资料的共享平台,可以提供不同来源的资料数据。本文利用现有的卫星影像成果,整合公开资料,进行了数字线划图的制作,为如何利用公共测绘资源提供了实例。

With the progress of science and technology, the accuracy of satellite image has been able to meet the production of specific scale topographic maps. As a shared platform for public resources, internet can provide data from different sources. Based on the satellite image and integrating public information, the production of DLG has been carried out. It provides an example for how to make use of public surveying and mapping resources.
