曹凤海,易昌华,殷学涛,罗桂圆,柳安青.GeoTIFF格式分析及其在测量中的应用.物探装备,2015,25(1):52-57GeoTIFF地理信息的标签图像文件格式在物探测量等领域得到了越来越广泛地应用。本文详细地论述GeoTIFF用于存储地理信息的具体技术途径和六个地理标签的结构、含义。以DEM数据的读取和应用为例,介绍了GeoTIFF在测量中的应用,列出了以GeoTIFF格式存储的DEM数据分析以及某一点对应高程值(灰度值)提取的实现代码。
Geographic tagged image file format, GeoTIFF, has been used more and more widely in geophysical survey. This paper discusses theprogress of geographic informationstoring in GeoTIFF format. The parts and meaningsof six geographic information labels are introduced too. In addition, take DEM data as an example, this paper describes the application of GeoTIFF in surveying, makes DEM data analyzing and shows how to achieve a certain elevation values （gray） code.
