摘要
Google Earth图像以精度高、直观形象、操作简单和免费使用等特点,深受广大用户的喜爱。以成都理工大学为例,探讨了利用Google Earth图像,结合CASS强大的制图功能,进行图像处理及信息提取的过程;针对GoogleEarth图像上被阴影遮蔽的信息,提出了通过地面少量实测来弥补的解决办法;最后分析了Google Earth产品的优缺点及应用前景。
With high precision,visual pattern,simple operation,free access and so on,Google Earth image is well received by vast users.Taking Chengdu University of Technology for example,the author discussed image processing and information extraction by using Google Earth image and CASS.For how to extract graphical information covered by shadow from Google Earth image,the author put forward a method of combining image measurement and ground measurement.Finally,the author pointed out applicable fields of the method,and analyzed the advantages and disadvantages of Google Earth products and their application prospects.
