摘要
根据对环北京地区沙化土地野外光谱数据采集工作 ,探讨了光谱数据采集的技术方法选择 ,并以ASDFieldSpecTM FR全波段野外光谱仪所测数据为例进行分析 ,对影响光谱数据共享的辅助数据进行了讨论。
According to the field spectrum data collecting within Beijing area, some technical methods in data acquirement are discussed, which include environment condition, analysis of the character of desertificated land, strategy of sampling and selecting of instrument. Spectrum data collected by the ASD-FR field spectroradiometer has been used as an example to show how the errors in data collecting can be eliminated. Ancillary data that effect spectrum data sharing are also discussed.
