Geological structural interpretation of Qinglong area in Hebei based on multi-source remote sensing data

The spatial resolution of multi-spectral remote sensing data can satisfy multi-scale structure interpretation. The authors took Qinglong area in Hebei as the study area, utilized the comprehens ive advantages of ETM+, Spot6 and WorldView3 data of the study area to interpret the geological structures at two different levels from ETM+ data with 15 m resolution and Spot6 data with 6 m resolution to WorldView3 data with 0.5m resolution, and obtained a goo d result. Firstly, based on ETM+ data interpretation structure, the band operation results of SPOT6 data are used to indirectly reflect the structure informat ion, and the high resolution WorldView3 data is integrated to construct the interpretation analysis. Finally, the interpretation structure information is revised based on field validation. The results show t hat multi-source remote sensing data have the characteristics of high resolution, accuracy and high efficiency in geological structure interpretation.
