Using classical algorithms of vector data compression, such as the Douglas-Peucker algorithm, to simplify the natural shoreline into direction-line, ignores the special requirements of a guarantee of national marine interests. To solve this problem, this paper proposed an improved Douglas-Peucker algorithm. Firstly choose the convex points of the natural shoreline as an alternative set of points; then filter segment points from convex points based on angle and distance; finally, divide the data into several parts in order to perform the Douglas-Peucker algorithm, and control the threshold of every part to effectively select feature points and protect national maritime interests. This paper uses ArcGIS 10.0, Visual Studio platform, and C# language to carry out the algorithm design, and choose a local coastline of Jiangsu province to conduct experiment. The results show that, compared with the Douglas-Peucker algorithm, the improved Douglas-Peucker algorithm improves the area ratio by 0.19%(0.17%-0.20%), and compression rate of coordinate points by 13.22% (9.48%-16.95%), and the accuracy of curve simplification also improved.","PeriodicalId":286908,"journal":{"name":"2013 21st International Conference on Geoinformatics","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126521139","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Marine oil pollution in the coastal ship oil spill accidents not only bring huge economic losses, but also directly destroy the marine ecological environment [5]. For sudden marine oil spill pollution events, simulating the path of the oil spill in order to understand the oil spill has become a problem that is urgently needed to be solved. At present, our country has not established a comparatively perfect, strong operability of oil spill emergency monitoring platform. For a major oil spill accident handling, the country appears to lag behind the response of other countries. Thus establishing an efficient, real-time monitoring of marine oil spill emergency platform is particularly important. In view of marine oil spill accidents, this paper establishes the analysis of the oil spill monitoring platform architecture with the .NET platform structure, and creates the oil spill monitoring analysis module based on GIS using C# combined with the ArcGIS Engine secondary development kit. This paper has solved the probability and statistics of oil spill monitoring, automatic oil spill thematic map output, automatic oil spill statistics generated key technologies, such as to provide research model for marine oil spill surveillance, as well as the oil spill emergency response simulation that offerstechnical support of spatial analysis and expression.","PeriodicalId":286908,"journal":{"name":"2013 21st International Conference on Geoinformatics","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126214795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Several problems that exist in current researches on map symbols were analyzed: focusing on the visual graphics but paying little attention to the semantics, constructing the structure model of map symbols without unifying the concepts and visual graphics, and not fully investigating the relationship among different symbols. A concept of Symbol-morpheme was put forward which was the minimum graphic-concept unit in the map symbol structure, and was the bridge which connected the visual graphics and geographical semantics of map symbols. A map symbols description model was constructed which centered on the Symbol-morpheme and considered the visual graphics and concepts comprehensively. This model linked the cognitive structure of map symbols with the human's cognitive structure of geographical objects. A design method of semantic-driven hierarchical map symbols was proposed, in which the control of semantic relationships made the map symbols system more regular and scientific. And a group of cognitive experiments had been carried out which shown that the propounded method had a superior performance in cognitive efficiency and higher transmission efficiency in the analog process of information transmission.","PeriodicalId":286908,"journal":{"name":"2013 21st International Conference on Geoinformatics","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115201081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
