A sensor web resource ontology for the dynamic disaster process monitoring was proposed in this paper, which can focus on the characteristics of the observation resources for diverse applications during different monitoring processes. To verify the feasibility of the method, case studies were conducted, including the semantic modeling of the in-situ monitoring and the remote sensing monitoring for flood disaster processes. The results demonstrated the effective sharing of various observation resources with different processes for environmental monitoring.","PeriodicalId":142380,"journal":{"name":"2018 26th International Conference on Geoinformatics","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132394002","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}

During information exchange, Industry Foundation Classes (IFC) containing rich building information is the most used data format in BIM. However, GIS does not the capacity to directly consume the data in IFC due to data incompatibility between the two systems. Consequently, IFC files have to be transformed into a format that is accessible to GIS. Shapefile is one of them, given its popularity in geospatial science. This study tests the different formats and methods for transforming IFC to shapefile, assesses their performance, in order to offer a ranking, from which better decisions could be made when choosing an appropriate intermediate data format. The results show direct transformation from IFC to shapefile retained the most geometry and semantic information. If the direct transformation method does not work in some cases, 3DS, VRML, or SKP could be used as alternatives to retain most of the information, while DWG, DXF, KML, and KMZ should not be considered due to their poor performance in the test.","PeriodicalId":142380,"journal":{"name":"2018 26th International Conference on Geoinformatics","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130408125","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}

Aiming at a large number of hydrogeological data in the project, establishing a standard description of unified information and sharing mechanism can effectively solve the problem of serious data loss and low information utilization rate. At present, rock tunnels are lack of unified standards for hydrogeological data. This paper takes the Laoying tunnel of Yunnan Province as the background to design a rock tunnel hydrogeological information model. The purpose is to unify the storage and transmission of data and solve the problem of file format incompatibility between different softwares in tunnel engineering. In addition, this paper proposes a new groundwater table estimation method, which has higher accuracy than the traditional method of using borehole data to interpolate, and thus can further optimize the hydrogeological information model.","PeriodicalId":142380,"journal":{"name":"2018 26th International Conference on Geoinformatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130666788","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}

This paper considered the northwestern part of Yunnan Province as research area, and took the elevation, slope, rainfall, landform, evapotranspiration and NDVI (normalized difference vegetation index) as influential factors. Followed by two accuracy indicators TPR and FPR, best models of Logistic Regression (LR), Support Vector Machine (SVM), and Random Forest (RF) were established. Then a same test set were used to compare the effectiveness of them. The result shows that as a combined classifier, RF performed the best with TPR is 83.10% and FPR is 0.48%, SVM took second place with TPR is 74.99% and FPR is 1.98%, and LR is inclined to predict occurrence, causing its high FPR 22.71%. The LR, SVM and RF models built in this paper are quite effective and provide a theoretical base for prevention and reduction of debris flow. Additionally, 41 mud sensors data distributed in this region were collected, based on which the debris flow probability of these area were obtained by LR model to explore the effect of mud on debris flow. Experiments find that in some basins, mud has a positive impact on debris flow, and in the remain basins, mud may be slightly influenced by rainfall and thus cause a negative effect on debris flow.","PeriodicalId":142380,"journal":{"name":"2018 26th International Conference on Geoinformatics","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133351659","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}

Strengthening traffic accessibility has the most direct impact on regional development. As a case study, Nanjing, an urban agglomeration transportation hub of the high-speed railway in South Jiangsu, was selected as the object of this research. In this study, we conducted the cumulative cost distance algorithm in geographic information system (GIS) to construct the accessibility evaluation model based on minimum distance partition, which helps to analyze the effect on the accessibility pattern of regional central cities in urban agglomerations scale. The results indicated that the high-speed railways increased regional space-time contraction and reduced the time cost between areas to improve the overall level of regional accessibility. Time costs of each node to Nanjing diminished slightly, and the accessibility gap narrowed gradually. More cities achieve cross-city day flow and result in Urban Integration effect which can be profound influence on the economic and spatial structure. Furthermore, HSR services are intended to be medium-and long-distance connections as the isochronous rings of 90 min and 120 min significantly expanded the scope. Also, the improvement of accessibility by high-speed railway has the Hourglass Effect according to city scale.","PeriodicalId":142380,"journal":{"name":"2018 26th International Conference on Geoinformatics","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122373014","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}

An important research direction within localization is to develop schemes by using optimization methods. In this paper, invasive weed optimization (IWO) algorithm is used for the field of WSNs localization. Furthermore, two measures are proposed to improve the performance of algorithm. Firstly, the idea of proactive estimation is put forward and used to narrow down and restrict the feasible solution space, which helps to speed up the global search. Then, an adaptive standard deviation (SD) is presented to replace the constant SD in the original IWO, which helps the algorithm to improve the convergence speed, and make it more exploitive. Results show that the proposed localization algorithm achieves higher accuracy with lower network costs and energy consumption compared to the existing schemes.","PeriodicalId":142380,"journal":{"name":"2018 26th International Conference on Geoinformatics","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117169590","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}
