Jiaozhou Bay is located in the southeast coast of the Shandong Peninsula, in feet (3 6 ° 0 2'3 6 \N, 120. 17'30 \The Jiaozhou Bay bred excellent Yiduntaigang, industry gathering with Jiaozhou Bay, led from the page the Qingdao economic, social, and cultural development of various undertakings, its multi-faceted, multi-angle study has important implications . In the domestic marine function zoning of the coastal provinces, Qingdao City, the first large-scale remote sensing data SPOT-5 HRV multispectral data resolution of 10 m × 10m panchromatic data resolution of 2.5m × 2.5m . SPOT remote sensing data, in combination with other auxiliary data (such as digital elevation models, topographic maps, water depth and seabed sediment data), quantitative study of Jiaozhou Bay, all kinds of functional characteristics and the formation of various types of maps with higher accuracy, and ensure the marine functional zoning scientific, efficient, reasonable. This work relies Qingdao marine function zoning project sub-topics marine geological environment studies, based on the French SPOT-5 remote sensing data, combined with GIS and RS technology, complete the following aspects: (1) spatial data coordinate transformation GIS seamlessly integrate multi-source data, is fundamental to the correct basis for spatial analysis, and the results show. This work was to collect a large number of paper maps data (such as topographic maps, water depth, topographic maps, etc.) for research needs, different maps from different sources, its projections and coordinate baseline. Therefore, the need spatial data coordinates unified. Work, first of all maps scanned into a digital image of the computer, and then after corrective graphics deformation error, last vectorization, unified paper selects Xi'an 80 coordinate system, Gauss - Kruger 3 degrees with a projector. (2) The most notable feature of the remote sensing image is the large amount of data and images rich in detail, and remote sensing technology is so far the only means to be able to provide a wide range of dynamic observation data, Remote Sensing Image image processing technology used in the nation's coastal provinces and cities take for granted marine function zoning. This work to study the characteristics of the SPOT-5 remote sensing image information, the characteristics of the data characteristics and the target of the remote sensing area, the geometric correction of remote sensing images, radiation-enhanced, and discussed a variety of fusion technology, the use of the three methods ( PCA method, HIS conversion, four algorithms) their panchromatic images (2.5m) and the integration of multi-spectral images (10m) obtained the principal component analysis, and qualitative and quantitative evaluation of multispectral images reserved information the most advantage.
