Research on the Chinese South Sea Reefs Water Depth Inversion and Remote Sensing Thematic Image Drawing

摘要

The South China Sea reefs, which has many islands and rich mineral resources and important military-strategic position. It makes use of remote sensing mean which have advantages about real-time , no restriction by geo-space and high-resolution to detect for the South China Sea has a very important practical significance for China. This paper considers a high-resolution IKONOS satellite image as the research object, bases on principle of remote sensing inversion depth, with the optical properties of water, proposes double-band ratio method for the study area to do deep inversion. In the case of the lack of measured data, this paper puts forward the relative depth inversion model drawing relative isobaths graphs and then complete remote sensing thematic image making. The research depicted in this thesis it can be obtain the distribution of reefs, compendium isobaths graphs information and obstruction in underwater.
