| Abstract: | Using Landsat ETM data, the authors applied remote sensing to geological mapping. First, the image
processing (using ER Mapper 6.2 platform) mainly based on the principal component analysis, RGB-HSI-RGB
transformation and false-color composition was adjusted according to several geological sections in the working area
in order that the major lithological units could be distinguished from each other on the image. Then ETM Pan as well
as the 15 m resolution band was used for promoting some final images to 1︰50,000 scale through data fusion.
Moreover, geological mapping was carried out by using ARCVIEW 3.0 a platform on the basis of the images and in the
light of the cross section studies and all of the known facts. Certain lithological boundaries and faults were
selected to be inspected in site and the image processing was adjusted again to the inspection result. In the end,
the geological map was fulfilled through the final modification based on the further processed images, general
analyses and editing on the ArcInfo 7.1.1 platform. Field examination shows that this geological mapping method
using remote sensing is accurate and suitable to the areas characterized by limited vegetation and soils as well as
tough topography. |
