Abstract

Abstract

Bounded by the Taiwan Strait, the north part of coastal zone in China is long and narrow in north-south direction, the south part is also long and narrow but in west-east direction. The imagery database of marine cadaster should adapt to this particular long and narrow spatial form. The paper carried out a composite block model of Binary Tree and Quadtree model, and according to this model, presented an improved Morton code—"CMorton code".We used multi-resolution remote sensing data of the Changjiang Estuary,Hangzhou Bay in north-south and coastal image in Fujian Province in west-east direction to test the coding method.The result showed that, compared with the usual row-column number coding, the CMorton code can significantly shorten the construction time cost of data block, it can satisfy the real-time visualization of marine cadaster data and efficiently adapt to the spatial form of Chinese marine cadaster imagery data.
