Geovisualization provides theories, methods, and tools for visualizing processes on the earth’s surface. One of the key challenges of the field is to find interesting and engaging ways to display geographical data. In this paper, we focus on the Augmented Reality (AR) Sandbox. An AR Sandbox combines a box filled with sand with a 3D camera and a projector to explore the topography of the sand terrain in real time and allow water flow simulations. This direct interaction between user and topography makes the AR sandbox a fascinating, explorative tool in the field of geovisualization.In this paper, we give an overview about how an AR Sandbox is built, what components are required, and how configuration, calibration or adding additional features work. We also discuss ways to improve the usability of the AR Sandbox or change its appearance to make it more suitable for specific use cases in geovisualization. Of particular importance is the DEM tool, which allows real-life data to be remodeled in the AR Sandbox to explore the terrain, create rainfall simulations, or export the current terrain as a DEM. Further advantages of using an AR sandbox for geovisualization are the hands-on methodology and gamification aspects, which motivate people to interact with topography and improve learning effects in the geosciences.\u0000","PeriodicalId":233935,"journal":{"name":"Proceedings of the ICA","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115182486","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}

With the rapid development of remote sensing, geographic information (GI), artificial intelligence (AI) and other technologies, China is continuously strengthening emergency rescue innovation and numerous breakthroughs related to emergency rescue technologies and equipment which have been made through the National Key Research and Development Program. This paper first proposed and illustrated the concept, connotation and characteristics of integrated space-air-ground emergency rescue communication command from the perspective of mapping and geographic information, and then analysed the challenges faced by the integrated space-air-ground emergency rescue communication command in China. Subsequently, a space-air-ground emergency rescue command theoretical system is introduced by combining broadband emergency communication, accurate acquisition of real-time disaster information, disaster situation and scenario projection, emergency communication command services, and resilient emergency rescue command. The proposed integrated space-air-ground emergency communication and command design concept will be applied for China's disaster emergency rescue and command in the future to comprehensively improve the emergency rescue communication and command capability in China.\u0000","PeriodicalId":233935,"journal":{"name":"Proceedings of the ICA","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114819025","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}

On a daily basis, hundreds of thousands of people in the City of Cape Town rely on road-based public transport as a means of commuting. A major factor that influences the passengers’ experience is the travel time to reach a desired destination. Due to various physical and operational factors, some sections of the road network experience high congestion and travel time delays during the morning and afternoon peak periods. Quantifying these delays, and the number of road-based public transport passengers exposed to the delay along a specific road section during a peak period allows informed decision-making and prioritisation. GIS and spatial data analysis are powerful tools to determine where and when such delays occur. Various spatial data sets exist that were jointly analysed to quantify the delay and the passenger volumes exposed to the delay on the city’s public transport network.\u0000","PeriodicalId":233935,"journal":{"name":"Proceedings of the ICA","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116916558","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}
