He has coordinated or participated in more than 36 European and National research and development projects under various funding frameworks (incl. FP6, FP7, H2020). His publication record comprises of numerous articles in renowned Journals, Conferences, and Books (e.g. within the Remote Sensing and Digital Image Processing Springer Verlag Book Series), and editorial work (e.g. the recent editing of the Special Issues ‘Remote Sensing in Ecosystem Modelling’ and ‘Sentinel Analysis Ready Data’ of the MDPI Remote Sensing Journal and the ‘Monitoring Land Cover Change: Towards Sustainability’ of the MDPI Land Journal). Within the recently completed BIO_SOS FP7 Space, H2020 ECOPOTENTIAL, and ongoing H2020 E-SHAPE and SnapEarth projects, he developed and applies Earth Observation online data services’ modules and open data cubes for the calculation of Essential Variables related to Protected Areas across Europe and beyond. He chaired the European Association of Remote Sensing Laboratories (EARSeL) from 2012 till 2014. He is the active Chairman of the Special Interest Group ‘RS in Land Use & Land Cover’ of the EARSeL. In this framework, he is the co-coordinator of various international Symposiums and Workshops, with the last one being the 3rd EARSeL Land Use Land Cover (LULC) & NASA Land Cover Land Use Cover (LCLUC) Workshop at Chania on July 2018 with the title ‘Land-Use/Cover Change Drivers, Impacts and Sustainability within the Water-Energy-Food Nexus’. He serves as an active contributing member to the GEO Global Ecosystem Initiative (GEO ECO) and in the new Ecosystem Function Working Group (ECOFUN) of the GEO Biodiversity Observation Network Flagship (GEOBON) within the Group on Earth Observations. His activity is also recognized at the newly established Mediterranean Regional Information Network (MedRIN) and the South Central and Eastern European Regional Information Network (SCERIN) of the GOFC-GOLD (Global Observation of Forest and Land Cover Dynamics) and GTOS (Global Terrestrial Observing System), where he serves as Lead in relation with the evaluation of the Global Land Cover Maps. He is also an active collaborator of the NASA LCLUC Program and member in the Copernicus Academy.


Abstract
Research in the environmental sector is growing in importance over time due to its strong relation to human wellbeing. Ecosystems supply provisioning goods, fulfil regulation and maintenance functions and deliver cultural services. All these benefits are crucial for human wellbeing and for the sustainable development of societies. EO plays an important role in their assessment, because it can be used for quantitative evaluation. Developments take place at an accelerating pace at global scale supported by the launching of international and European initiatives and programmes (e.g. Aichi Targets, Convention on Biological Diversity - CBD indicators, GEO BON, GEO ECO Initiative, ECO FUN, Copernicus Services, Mapping and Assessment of Ecosystems and their Services - MAES, European Nature Information System - EUNIS, Sustainable Development Goals - SDGs, H2020 relevant projects – e.g. E-SHAPE, ECOPOTENTIAL). New monitoring methodologies are now available that combine approaches in geo- and biosciences, remotely sensed data and in-situ observations. Satellite missions, such as the European Sentinels, provide a large amount of high-quality primary and secondary derived data useful for monitoring the environment and ecosystems. In-situ data are being organized and made available through international activities, such as the International Long-Term Ecological Research (ILTER) network and the Critical Zone Exploration Network (CZEN). Ecosystem models capable of assimilating the information from EOs are being developed. Recent technological advances, among others the Open Data Cube technologies and the ECOPOTENTIAL EODESM online tool, deliver unique capabilities to track changes in unprecedented detail using EO data, enabling effective responses to problems of national and international significance and considered supportive to ecosystem status assessments. Let us convene and discuss together about aforementioned, exchange experiences and knowledge during the 6th GISTAM event in Prague.



 

 

Integration of Multiple Spatiotemporal Demographic Data and Its Applications for Disaster Mitigation Planning

Brief Bio
Toshihiro Osaragi is Professor of School of Environment and Society, Tokyo Institute of Technology. He has served as Associate Professor in the same institution before, and was Visiting Researcher at the Centre for Advanced Spatial Analysis (CASA), University College London. He received his Doctor's degree of Architecture and Building Engineering from Tokyo Institute of Technology. He was one of the founders of Geographic Information Systems Association (GISA, Japan) and serving as Chairman of GISA currently. His areas of specialization include a wide range of cross-disciplinary fields. One of his main research projects has focused on how urban models and GIS technologies can support the spatial planning of our environment. As part of a long-standing interest in the transition process of land use, he has proposed a number of models to describe and simulate the dynamic changes of land use in the Tokyo Metropolitan Area. As for the planning support systems of public amenities, his research on public libraries has been well received. In recent years he has concentrated on some research projects, which are relating to disaster mitigation planning and operated under the full sponsorship of the Japan Science and Technology Agency (JST) and Japan Society for the Promotion of Science (JSPS). In these projects, spatiotemporal distribution of people in a city is estimated, and pedestrian simulation models are being constructed for describing evacuation behavior or returning home behavior of stranded people, together with some models describing building collapse, road-blockage, and fire spreading. He received some best paper awards at international conferences, which include GISTAM 2020, EnviroInfo 2019, ISCRAM 2017, AGILE 2013, AGILE 2012, and so on, by presenting research relating to the projects.


Abstract
There is a growing demand for data that facilitate highly accurate understanding of the spatiotemporal distribution of both moving and static occupants in urban areas. Currently, a large amount of population data are available, however none of the data provide an accurate understanding of the numbers and departure/arrival locations of moving people using detailed units of space and time. Also, their detailed attributes such as age, sex, and occupation, are not provided either. In this keynote lecture, we would like to introduce some methods to address aforementioned issues, and illustrate some numerical examples.
First, after evaluating the strength and weakness of existing population statistics, which are available in Japan, we propose a method based on maximum likelihood method is investigated for using their strengths to best advantage and compensating for weaknesses. The proposed method is then validated by comparing with another flow data, which featured spatiotemporal data including departure/arrival locations, and demonstrate that the present procedure provides accurate estimates for population flows. This method makes it possible to analyse urban regions from new and never-before employed points of view by identifying the number of transient occupants and their travel directions at any time on high level of detail.
Next, we construct a model that provides spatiotemporal distribution of occupants in urban areas that vary according to clock time, location, and building use classification. The time, location, and building use classification are employed as keys to integrate demographic information. Weekday and weekend data for the central wards of Tokyo are employed to create estimates of the number of occupants with their detailed attributes. Using numerical examples, we demonstrate that the proposed model can provide demographic spatiotemporal distributions with far higher value than before; in which the buildings people occupy, their reasons for being there, their sex and age bracket, and their residential locations, can all be identified.
Finally, we will demonstrate the application examples of integrated demographic data. When a large earthquake occurs, many people are presumed to have difficulty in returning home. However, no research has been achieved yet to discuss the congestion of supporting facilities for stranded people in terms of site, the number and spatial distribution. To address this problem, we construct a simulation model, which describes people’s behavior such as returning home or going to other facilities after an earthquake occurs. Using the model, we estimate the congestion of facilities which varies according to day of the week or the time when the event occurs, and demonstrate the effective methods for reducing the congestion, which include offering information for people and cooperation of private institutions.
