The loss caused by flood can be effectively eliminated or reduced through the rational utilization of water conservancy projects for scientific dispatching. The occurrence, development and dispatching of flood is a dynamic process, and the visualization of flood control situation is an important means to study the internal change law of flood disaster. Based on the actual requirements of large-scale flood dispatching and flood deduction in the basin, this paper develops a 3D virtual earth-ark platform (3DGIS-Ark) and constructs a 3D visualization system architecture of flood control situation deduction, aiming at the characteristics of large data volume, multi-dimensional multi-scale and dynamic simulation in the basin. Combined with the operational characteristics of flood deduction, the paper focuses on the seamless integration of massive data and 3D roaming, 3D flood control situation deduction and disaster loss estimation. The system software has been successfully applied to the flood control situation of the Yangtze river basin, giving full play to the advantages of 3DGIS analysis and 3D display.","PeriodicalId":365314,"journal":{"name":"Proceedings of the 2020 3rd International Conference on Geoinformatics and Data Analysis","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122034279","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}

It has fundamentally revolutionized the mechanism by which information is disseminated and utilized, in order to be closely involved in the physical world and human activities. However, from global perspective, factors such as the continuously increasing complexity of structure and function of cyberspace, the rising benefits from both economic and political aspects, the exposing of inherent vulnerabilities have all contributed to even severe security threats and risks targeting cyberspace, which have become a key factor in national security in the challenging situations. Strategic cyberspace risks are different kinds of core, structural and systematic risk that if were neglected to prevent and control, significant damage to cyberspace will be dealt and cause great economic loss. Aiming at exploring new ways and tackling with such strategic threats, the concept, elements and relationship between tactical and strategic risk in cyberspace was studied. A knowledge-based cyberspace strategic risk warning and assessment system with four data-driven layers was built, and two scenarios of heartbleed and Teamviewer vulnerability event are investigated to suggest possible use cases for our system.","PeriodicalId":365314,"journal":{"name":"Proceedings of the 2020 3rd International Conference on Geoinformatics and Data Analysis","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121412678","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}

However, obstacles to GPS signal at the finest flight altitude might avoid accurate retrieval of camera station positions. The aim of this investigation is getting accurate photogrammetric products in UAV linear projects by improving the georeferencing, using a little number of Ground Control Points (GCPs) in a small part and improved camera station positions. This technique is low cost and helpful in disasters especially in projects that cannot be distributing GCPs all over it. DJI PHANTOM 4 PRO acquired 390 images in three flight lines with average flight altitude about 40 m along 1000 m length of study area. The ground sample distance (GSD) is about 1.2 cm. The average end lap and side lap are about 80%. The dimension of area covered by this area is 1000 m by 90 m. Methodology of enhancement GPS auxiliary data is by using Linear Relation (LR) model. In LR model, correlation for the same specified images between the auxiliary by GPS on UAV platform and computed photo centers coordinates through georeferencing using a little of GCPs in small part of project has been determined. The specified images only contained GCPs, which are used in georeferencing. Moreover, using LR model to generate new coordinate values for the rest images to use them in georeferencing. The errors assessment was done using 86 checkpoints (CPs) not used in georeferencing distributed all over the study area. The using of the generated photo centers coordinates by LR model with the four GCPs gives accurate results in georeferencing better than using only the same four GCPs.","PeriodicalId":365314,"journal":{"name":"Proceedings of the 2020 3rd International Conference on Geoinformatics and Data Analysis","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128960685","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}

Therefore, in this paper the study focuses on six factors of spatial terrain and tree characteristics, which are used to build the estimation model of carbon storage. The research region is Dalingshan Forest Park in Dongguan City. The carbon storage is considered as the dependent variable. The six factors of terrain and tree characteristics, such as slope, elevation, tree height, crown density, tree diameter, and tree age, are considered as the independent variables. The relationship and model between the carbon storage and the six factors are researched by the method of regression analysis. By non-linear regression analysis, the estimation models of carbon storage are built based on the six factors. By using the non-linear regression model, the carbon storage of every compartment in Dalingshan Forest Park is estimated then visualized by means of thematic map.","PeriodicalId":365314,"journal":{"name":"Proceedings of the 2020 3rd International Conference on Geoinformatics and Data Analysis","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127956550","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}
