In such kind of society, these technologies are used for solving social problem by integrating cyber-physical space (SCPS). The authors focus on (1) digital technology as a tool to solve social problems like as lack of labor, (2) elements of geospatial technologies and (3) diversifying management agencies and services. High precision three-dimen-sion map and positioning system, indoor positioning system, SfM by cloud service and next generation mobile communication system are expected to be necessary tools to develop future society. Es-pecially, examples on elemental and integrated technologies related to next generation mobility by drone and autonomous driving, agriculture and emergency responses are introduced.

Specifically, in each targeted tweet of noise reduction, a morpheme n-gram analysis of only nouns was performed, those with a high combination frequency of nouns were generated as noise filters. The results suggest that there is a certain degree of effects of noise reduction method under the condition of morpheme 4-gram of noun and frequency threshold 3 or 5 in the case where the number of tweets to be processed is at least about 110 or more.","PeriodicalId":177070,"journal":{"name":"Theory and Applications of GIS","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124813623","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}

Especially, it is difficult to grasp the condition of poor people because some of them live in illegally occupied areas. In this research, therefore, the deep learning model to grasp the residence of poor people at the building level from satellite image and household survey data was developed. This model can classify buildings into three levels: poor, middle and rich. Three methods for creating labeled training data were considered and the influence of building area, land use and elevation data on estimation accuracy was also considered. The accuracy of the method with the highest estimation accuracy was 81.8%. The result can be visualized by using GIS and it helps people to understand where many poor or rich people live.","PeriodicalId":177070,"journal":{"name":"Theory and Applications of GIS","volume":"77 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117260317","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 article reviews the concepts of IoT and CPS from the perspective of geospatial spaces and clarifies the complementary relationshp of the two technologies. Two forms of CPS were discussed: Pseudo-CPS (PCPS) which projects spatial data on a display without interaction among data sources and True-CPS (TCPS) with handles data sources deeply and semantically. While PCPS is widely industrialized TCPS is in its infant, lack of common schemes and platforms for data sharing, security and privacy etc. Dissolving the barriers requires collaborations cross sectors and disciplines. A transformation of our mindset on GIS from ‘location + attributes’ to ‘location×attributes’ is recommended for creating value-added GI services.","PeriodicalId":177070,"journal":{"name":"Theory and Applications of GIS","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116548278","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}

Cycling tourists often take these routes for inter-destination movement. However, it is difficult to gather data concerning such types of movement with existing investigation methods such as questionnaires. This study examines the effectiveness of volunteered geographic information (VGI) for analyzing inter-destination movement of cycle tourists and regional factors affecting the movement. Hokkaido was selected as a suitable targeted area. As the result, comparing the behavioral indicators derived from VGI and existing questionnaire survey, we could show that VGI were effective in capturing the actual condition of cycle tourist movement. In addition, analyzing the regional factors affecting cycle tourist movement based on Spatial Autoregression Model allowed us to detect important regional factors, including coastline, trail station and accommodation.","PeriodicalId":177070,"journal":{"name":"Theory and Applications of GIS","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132820709","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}

We present four mixed integer liner problems for design bus route network that maximizes the capturing amount of origin-destination (OD) flow and calculating the number of vehicles and mileage of DRT that carry flow which bus does not pass. The OD flow is estimated by population and facility distribution. Through three case studies, we observed that the combination of bus and DRT is economically advantage due to a linear concentration of demand distributions. Moreover, it shows that DRT system has advantages in an environmental indicator, and access movement caused by bus service contributes from a healthy viewpoint.","PeriodicalId":177070,"journal":{"name":"Theory and Applications of GIS","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116306031","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 addition, OSM has attracted various kinds of users due to its worldwide coverage and open license. However, as volunteer mappers have generated or have edited OSM data, data quality such as positional accuracy, completeness and freshness is heterogeneous in different regions. Therefore, it is required and important for OSM users and mappers to evaluate data quality quantitatively and regularly. Especially, in Japan, there are not existing researches dealing with nationwide usability of OSM road data by comparing with other road data. Toward discussing significant criteria of data quality assessment, this paper describes the comparison results between OSM road data and Digital Road Map (DRM), on the perspective of positional difference and area coverage in 1 km grids and city boundaries.","PeriodicalId":177070,"journal":{"name":"Theory and Applications of GIS","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126756550","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}
