It's a trend to research on the Open GIS based spatial information analysis and publishing. This article develops the Marine oil spilling monitoring information analysis & publishing system based on DotSpatial, the upgrade version of the open-source .NET development of component library. In this system, the oil spilling monitoring information is visualized, rendered, analyzed, and finally published to the web. However, open GIS is functionally limited and instable. It can not read the spatial information of RS images well, and the mapping and outputting module is unstable. This article solves some technical problems. For example, the spatial data are processed such as re-projected via GDAL (Geospatial Data Abstraction Library) to match the images layers with the vector layers. Vector oil spots data are generated and rendered, and the major axis and minor axis are drawn. Moreover the map extent to output can be determined by dragging a rectangle by GDI+, and the decorating of the map to putout is also improved. By adopting several developing method comprehensively, this article does research on the system development based on Open GIS platform to provide reference for other similar system researches and developments of spatial information expression and analysis.","PeriodicalId":286908,"journal":{"name":"2013 21st International Conference on Geoinformatics","volume":"18 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":"125206912","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}

And combined with the statistical data about the Zhengzhou transportation, we estimated the CO2 emissions of Zhengzhou residents commute and obtained some conclusions: in 2001-2010, the carbon dioxide emissions of Zhengzhou urban residents is growing, and its growth rate is similar to the growth of the private cars of CO2 emissions and the traffic CO2 emissions of per person. The change of CO2 emissions of buses and taxis are quite minimal, whose emissions ratio in the total carbon dioxide emission of residents daily travel is decreasing gradually; the traffic low-carbon standard of Zhengzhou residents is a high-carbon mode due to the low-carbon index, which is greater than 1.2 except in 2005, which for the city residents transport CO2 emissions, the growth rate was much greater than the growth rate of per capita consumption expenditure. The increasing income and the growth of daily commuting distance could induce to more motor vehicles and longer annual mileage. The further optimization in the public transport network not only promotes a small increase in carbon emissions from buses, but also will inhibit the rapid growth of carbon emissions from private cars and optimize the structure of the resident's transportation carbon emissions, which may be an opportunity for the carbon reduction of the residents daily commute.","PeriodicalId":286908,"journal":{"name":"2013 21st International Conference on Geoinformatics","volume":"258 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":"133758073","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}

Hence, the clients cannot be served with real-time response. In this paper, we propose VegaCache, a distributed in-memory caching scheme, to provide low-latency access for time-critical geospatial workloads. VegaCache has three significant characteristics. First of all, it is composed of tunable memory pools maintained by commodity cluster and thus its capacity can be increased linearly with more nodes. Moreover, a data replacement model is designed to determine loading hotspot data into and swapping out victim data from the distributed cache. In addition, we design a localized caching model to reduce data transfer delay with consideration of geographic proximity and geospatial access patterns. Comprehensive experimental results show that VegaCache is able to provide sustained I/O throughput and high efficiency access and thus could meet the requirements of geospatial applications.","PeriodicalId":286908,"journal":{"name":"2013 21st International Conference on Geoinformatics","volume":"66 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":"116941411","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}
