Abstract An optimally planned route is the foundation of a safe and economical navigation. This article proposes method for shortest time routing based on composite influence multidynamic elements. First, an instantaneous model constructed static depths from chart grid tidal in sea area, then collection obstacle areas are acquired navigability analyzed. Second, search made path using dynamic programming method. Finally, further optimized by strategies that involve excluding outside...
The Spatial Data Mining as an important step of knowledge discovery process means to extract the unknown, valuable and operable relationships, patterns or trends for decision support system from large spatial databases data warehouse. With rapid development marine surveying mapping technology computer storage devices, massive amounts appears in Marine Geographical Information System. Traditional processing could not discover potential knowledge. How make full use obtain implicit rules,...
Digital watermark techniques are now eventually becoming one of the most reliable methods to prove copyright both observed and processed digital marine data, especially when data have be distributed through Internet. The article introduced research work, which we finished on application improvement for copyright-proving remotely sensed topographic cartographic with emphasis mathematical models methods. Discussions different were made based results our experiments. also put forward several...
Chart datum is a vertical reference of ocean depth, which can give the spatial information for Marine Geographic Information Systems. Its establishment and maintenance fundamental work hydrography cartography. Paper introduced chart datum's role in datum, analyzed basic principles to determine studied structure bathymetry based on datum. In end, it summarized international current algorithm, model study progress For construction digital hydrographic information, necessary reconstruct system...
In order to improve the "trinity" new military personnel training system of academy education, practice and vocational we try adjust optimize teaching concept, means methods mathematical statistics online in probability education courses. teaching, through Minitab software computer technology, have made active exploration data analysis, theory, experimental design, which is very helpful results statistics.
Point cloud classification is an important aspect of point data processing and the hot research direction at present. This article improves IMRG algorithm for segmentation, uses k-means clustering method to obtain sets intermediate levels. The features each level set are extracted fused, then proposes based on random forest method. Through two experiments, it has been shown that integrates multiple can effectively improve accuracy classification.The proposed in this better compared other...
In recent ten years, with the rapid development of computer and navigation technology, a great deal national vector digital charts in different scales have been produced issued. While, even up to now, effective update mechanism has not erected, which makes can be devoted into daily use. Obviously, it is significance build for charts. To improve service standard charts, based on international modes, paper only brings forward assume founding chart system client-server (C/S) mode, but also...
