Pleiades遥感数据融合在地理国情调查中的应用

Application of Pleiades Data Fusion in Geographical Condition Survey Projection

地理国情调查工作中,数据源的选取和预处理在工程过程中占重要地位,由于航空影像数据获取时相受到一定的限制,因此,航天遥感数据作为影像有效补充。普利亚(Pleiades)航天数据以其优越的数据质量在地理国情调查工作中得到有效应用。本文从普利亚(Pleiades)地理国情调查应用出发,以探索全波段与多波段数据融合方法,提高数据可用性为目的,研究了遥感数据的几种融合方法,并对融合后的数据进行定量评价,从中选取最优方案,从而提高普利亚(Pleiades)数据的空间分辨率,达到数据分割,解译准确、精确的目标。

It is important that data resource is chose and proceeded in total project of geographical condition survey,due to the aviation image data acquisition phase receive certain restrictions,so the effective space data of remote sensing images. Pleiades,with its superior data quality is widely used in the geographical conditions survey work. From Pleiades application of geographic situation investigation,we explore the whole band and multiband data fusion method,improve the data availability,for the purpose of studying the methods of the remote sensing data fusion,and carries on the quantitative evaluation of fused data,choose the optimal solution,thus improve the spatial resolution of Pleiades,achieve the target of accurate and precise in segmentation and interpretation job.
