机载成像光谱数据的航带计算及其Internet发布

机载的成像光谱数据具有很大的应用价值,通过Internet发布有关成像光谱数据的信息,将推动成像光谱数据的应用。在用户检索成像光谱数据的过程中,有“何地”的数据是用户非常关注的内容。本文首先阐述了成像光谱仪的扫描原理与位置姿态数据的获取步骤,在此基础上指出机载成像光谱数据的航线与航带的计算方法。WebGIS是Internet上发布有关成像光谱数据的信息的有效平台,文章介绍了基于WebGIS发布有关成像光谱数据的信息的主要实现技术。

Calculation of the Strip of Aircraft-mounted Imaging Spectrum Data and Their Publishing Through Internet

Aircraft-mounted imaging spectrum data have been more and more widely used in many fields.Publishing the information about the imaging spectrum data through Internet will let more people use it.Generally,the data users want to know the location of imaging spectrum data when they search it.Firstly,the paper introduces the scanning principle and the step of getting the position and angular orientation of imaging spectrometer.Then,the paper presents the algorithm of getting the aerial route and aerial strip.The paper proposes to publish the information about the imaging spectrum data through WebGIS because it can show the retrieval results with texts and maps,which would help the user to obtain their interested information quickly.The key techniques of constructing the WebGIS are introduced too.
