Due to their being paper maps that are not published, it is difficult to get hold and utilize GLCM, although they are very useful in order to know and understand flood-disaster risks in local areas. In light of this, we established an online digital GLCM archive. The characteristics of the archive are: 1) GIS data release, and 2) arranged usage rules for re-use. First, we created raster GIS data from paper maps. Second, we obtained permission for re-use from publishers and the Geospatial Information Authority of Japan (GSI). Third, we arranged usage rules for re-use based upon ID. Fourth, we prepared map image APIs (Application Programming Interface), such as Web Map Service (WMS), XYZ tile and Tile Map Service (TMS). Fifth and finally, we opened the digital archive in March 2016.","PeriodicalId":177070,"journal":{"name":"Theory and Applications of GIS","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126593269","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}

In such a situation, the authors considered the method of noise reduction for improving the precision in the situation visualization by using geo-tagged tweets. Specifically, it is a study from the combination method of the autogeneration of noise reduction filter by using Natural Language Processing (NLP), and the noise reduction by the multiple people in the same time zone and near distance. In the NLP method, precision level at the about 53% was observed from the test by using the morpheme-3gram. And nominal significant difference at the 0.5% was observed in comparison with non-filter method. In the near distance method, precision level at the about 80% was observed, and nominal significant difference at the 0.5% were observed in comparison with NLP method. In the combination method of NLP and near distance, precision level at the about 84% was observed, and nominal significant difference at the 0.5% was observed in comparison with near distance method. Furthermore, in the verification by type of rainfall, it was revealed that the combination method can extract with higher accuracy than the NLP method or the near distance method from the extraction result with high accuracy exceeding 95% in the rainy situation. As a result, under the conditions in urban areas with many tweets, the results from this study on combination method indicated the certain effect.","PeriodicalId":177070,"journal":{"name":"Theory and Applications of GIS","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121222999","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}

The present study compares the future Japan through 2010–2060, estimated by National Institute of Population and Social Security Research, with all municipalities in 2010 from the perspective of demographic compositions classified by fiveyear age groups (0–4, 5–9, ..., 90+). The (dis-)similarity of compositional data can be measured with Aitchison distance, one of the core concepts of compositional data analysis. We create choropleth maps based on Aitchison distance. The maps, for example, indicate that the demographic composition of Sobetsu-cho of Hokkaido prefecture of 2010 is the most analogous of the future of Japan of 2060.","PeriodicalId":177070,"journal":{"name":"Theory and Applications of GIS","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132946882","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, it is generally assumed that such calculations require expensive software and data and therefore they may be considered not readily available. In the meantime, there currently are freely available spatial network data, GIS software, and web services for optimal path search, and therefore it may appear that it is possible to calculate the distance and traveling time for many sets of pairs of locations without spending any monetary cost. This study conducts an experiment of the calculation of the distance and travel time between locations using freely available data, software, and web services and reports the results. Specifically, we use OpenStreetMap data, QGIS, and Google Maps Distance Matrix API, in this experimental calculation. From the results, we demonstrate the possibilities and limitations of using freely available data, software, and services.","PeriodicalId":177070,"journal":{"name":"Theory and Applications of GIS","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116614087","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, some climbing beginners, especially middle aged and older people, who are overconfident on own physical strength sometimes encounter serious accidents and distresses. Actually, an accident and a distress in a mountain have also increased in these years. In order to achieve safer mountain climbing, it would be effective to aggregate and analyze individual climbing experiences in accordance with not only individual conditions but also mountain environments even if there is poor network connection and power supply. Therefore, this pa per aims to organize available datasets for analysis of practical behavior of mountain climbers, and describes methods to obtain climbing behavior data even for middle and older people under poor network and power environment. In particular, we implemented a cloud system to aggregate online-submitted climbing plans, and a check-in app using individual owned IC-cards. Finally, this paper describes some findings and discussions through our field experiments.","PeriodicalId":177070,"journal":{"name":"Theory and Applications of GIS","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125372690","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 there has been no prior research into this field in Japan. This paper presents a systematic review of geographical crime prediction and discusses their relevance to the Japanese context. We identify four categories of geographical crime prediction methods: (1) surveillance of space-time clusters of crime; (2) estimation of crime intensity based on space-time interaction; (3) prediction of crime risk based on environmental factors; and (4) prediction of crime numbers/possibilities. These categories are based on established theories and have been developed independently of each other. Finally, we suggest directions for future developments of this research field in Japan.","PeriodicalId":177070,"journal":{"name":"Theory and Applications of GIS","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130086613","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}
