Working GroupsWorking Group 3.1 – Geospatial Information Infrastructure for Smart CitiesPolicy Issues Geospatial Information Infrastructure is an enabling infrastructure that can support and integrate the increasing number of geospatial related sensors in cities and communities. Geospatial information infrastructure facilitates timely information services for citizens, governments and business across cities, regions and countries. It contributes to the delivery of improved outcomes in key areas such as urban planning, transportation, health, education, environmental management and supports economic development. The key aim of the working group is to contribute to improved decision making and outcomes in society through sharing knowledge and advances in geospatial information infrastructure and technology and their integration and enablement for smart cities at the local, regional and global levels. Chair Prof Kevin McDougall, Australia
Working Group 3.2 – Geospatial Big Data: collection, processing, and presentationPolicy Issues The definition of “Big Data” is complex and constantly changing, mainly based on the three Vs definition of their characteristics, such as “Big data represents the information assets characterized by such a high Volume, Variety and Velocity to require specific technology and analytical methods for its transformation into value”, or “data sets characterized by huge amounts (Volume) of frequently updated data (Velocity) in various formats, such as numeric, textual, or images/videos (Variety)”. A significant portion of big data is actually geospatial data, and the size of such data is growing rapidly at least by 20% every year due to the rapid technological development. Geospatial big data (GBD) collection methods include surveying, photogrammetry, remote sensing, LIDAR/Laser scanning, VGI, Mobile mapping systems, GNSS tracking, real time sensor observations, geo-sensor networks, IoTs, etc. The various types of GBD include raster data (e.g., geoimages-aerial, satellite, etc-, 3D objects), vector data (e.g., points, lines, polygons), and graph data (e.g., road networks, topological coverage, grid data). The “Volume” characteristic of the GBD deals with issues related to data storage and massive analysis; the “Variety” deals with issues related to data management models and structures as well as indexes; while “Velocity” refers to issues such as matching the speed of data generation and processing. However, the three Vs definition is further expanded with more characteristics, such as the one called “Veracity” which refers to quality assessment of source data, data improvement, etc. The increasing volume and varying format of collected GBD presents challenges in storing, managing, processing, analyzing, visualizing and verifying the quality of data. The target of Working Group 3.2 will be to investigate the opportunities and challenges and to propose a framework for understanding the ways that GBD may be obtained, processed, presented, shared and best used together with data derived from traditional surveying methods to provide richer datasets, and to be used in ways that are complementary. Through its work plan, the WG 3.2 aims to contribute significantly in meeting the UN Sustainable Development Agenda 2030 Goals and mainly in meeting goal 11 (Sustainable Cities and Communities) but also in goals 1 (No Poverty), 2 (Zero Hunger) and 13 (Climate Action), by raising awareness on how society -professionals/business, governments and people- can benefit from enhancing the usability of GBD. The efficient and broad use of GBD is anticipated to contribute in the good management of cities and communities, as well as in the efficient management of natural and/or manmade disasters and climate change impacts, but also in the improvement of the economy (e.g., minimizing costs/increasing revenue, supporting real estate market, enhancing formalization of ownership rights, property registration and security of tenure, etc.), and the improvement of agriculture (e.g., security of food and clean water) in the digital era. Improving surveyors’ digital skills in the collection, processing, management, sharing and use of GBD will also contribute in the creation of new job opportunities for young surveyors. The WG 3.2 will focus to motivate researchers in academia and industry, students, as well as delegates from the state sector to partner and join efforts to improve the value of GBD for the society as well as to take advantage of this value for improving the surveying profession. Inter-commission activity as well as collaboration with other FIG Com3 WGs in this field will be encouraged. Chair Prof Charalabos Ioannidis, Greece
Working Group 3.3 – User-Generated Spatial Content Empowering CommunitiesPolicy Issues Policy Issues The neogeography revolution of Volunteered Geographic Information (VGI) and Participatory Mapping encapsulates the idea of communities that create, share, visualize, and analyze geographic and geospatial information and knowledge. Spatial Data Infrastructure (SDI), as well as Spatial Information Management (SIM), can benefit greatly from the use and integration of this paradigm. User-generated spatial content is becoming a legitimate and reliable spatial, environmental and sustainable infrastructure on local and global scales. It enables citizens and communities to take part in processes having geospatial aspects, having a direct contribution on their life, empowering and mandating them as pertinent stakeholders. The emphasis of Working Group 3.3 will be on the investigation and identification of initiatives and projects that make use of user-generated spatial content as an enabler to processes, infrastructures and services to communities. Focus will be given to collection, processing, mining, interpretation, administrative, and analysis levels. Working Group 3.3 will search and learn new means and technologies on how to exploit and make use of user-generated spatial content and derived information to geoscientific disciplines, such as mapping, land surveying, GIS, land administration and cadaster, navigation – and more. Working Group 3.3 will aspire to motivate and work with scholars, professionals and communities, with the focus on developing countries, where this has the potential to contribute and strengthen utmost. Working Group 3.3 will aim to have joined and mutual interests and sharing of ideas and knowledge with other FIG Commissions, specifically Commission 2 (on Professional Education), Commission 7 (on Cadastre and Land Management) and Commission 8 (on Spatial Planning and Development). Chair Prof Sagi Dalyot, Israel,
Working Group 3.4 – 3D Cadastres (Joint Working Group with Commission 7)Policy Issues During the recent years 3D Cadastre has matured. The increasing complexity of infrastructures and densely built-up areas require a proper registration of the legal status (private and public), which can be provided only to a limited extent by the existing 2D cadastral registrations. Addressing this challenge has been the main goal of the International Federation of Surveyors (FIG) joint commission 3 ‘Spatial Information Management’ and commission 7 ‘Cadastre and FIG 42nd General Assembly 7/13 Hanoi, Vietnam 22-26 April 2019 FIG Commission 3 – Work Plan 2019-2022 Land Management’ Working Group on 3D Cadastres. The FIG Working Group uses the concept of 3D Cadastres with 3D parcels in the broadest possible sense: 3D parcels include land and water spaces, both above and below surface. The level of sophistication of a 3D Cadastre in a specific country will in the end be based on the user needs, land market requirements, legal framework, and technical possibilities. In the foreword of the FIG Publication ‘Best Practices 3D Cadastres’, FIG Past President Chryssy Potsiou comments that “we, as geo-information professionals, vendors, providers, managers, professionals as well as academics and researchers, are expected to develop services and tools to deliver administrative, economic and social benefits. Our colleagues, representatives of business, academia and public administration; managers of geodata from all over the world; young entrepreneurs and creative minds; all are working toward the same goal, trying to increase the “value” of geodata for the people. They do so in order to get more benefit, more transparency, more safety, more environmental quality, more growth, more fairness, more efficiency in governance of urban areas, more smart cities. No reality has a more direct bearing on the subject of 3 dimensional geo-information and cadaster than the growth of large cities, especially in the developing countries of the world, and especially in the phenomenon of the mega cities.” As cities grow they grow vertically as well as horizontally thereby introducing the element of the third dimension. Recent innovative thinking has introduced the concept of a multi-dimensional multipurpose land information system. It is a logical extension of the 3D cadastre concept, by adding the time dimension to the equation. In a discussion of “cost effectiveness” one must consider time, that 4th dimension that we speak of. In time, we are usually referring to land titles history and time-sharing rights, or how the shape and size of land parcels and cadastral objects change over time, but it is also a matter of time-cost in the construction of the cadastre, as well as the time/property value relationship. As the great cities of the world become mega, the value of land and its improvements grow as well. Thus the time/value relationship and its impact on land administration become central elements, and the need for continuing research on fundamental policy issues of technical administrative, legal and financial aspects of land administration will grow. The on-going process of improving land administration systems is crucial. It responds to the need for international research in building effective land administration infrastructures with modern information technology that will support the 2030 global policy goals for sustainable development.

Working Group 3.5 – GIS Tools for Spatial Planning (Joint Working Group with Commission 8)Policy Issues GIS tools hold great potential to support spatial planning practice. Ongoing developments in digitalization of data sets and communities further open up possibilities to apply GIS tools in spatial planning processes. The latter typically follow a cyclic pattern: (1) development of spatial policies, (2) policy implementation, and (3) monitoring and evaluation. Spatial policies FIG 42nd General Assembly 9/13 Hanoi, Vietnam 22-26 April 2019 FIG Commission 3 – Work Plan 2019-2022 range from strategic visions to land use plans that at operational level determine and distribute land use types. Together with legislation and rules, these spatial policies constitute the framework for implementation of spatial policies. Programmes, projects, enforcement mechanisms and the like can be used to implement spatial policies, depending on the situational context. Finally, monitoring and evaluation is necessary to measure whether policy aims are met or need to be adapted, which may lead to the development of new spatial policies.Due to the different nature of each phase in the cycle, GIS tools to support spatial planning practice will require different data specifications, functionality and usability features. This working group aims to gain a better understanding of developing useful GIS tools given a particular planning exercise, based on the different phases in the spatial planning cycle. Having appropriate and user friendly GIS tools available will create a positive spin-off in terms of enhancing information transparency and increase inclusiveness among participating stakeholders.

Working Group 3.6 – Geospatial Next (Joint Working Group with Young Surveyors Network)Policy Issues The Industrial Revolution 4.0 and the technologies emerging in daily life such as machine learning, AI and robotics; new challenges are at the doorstep for the societies. For millennia surveyors managed to benefit the technological advancements to answer the changing needs in respect of geospatial data/information for the societies. Yet, output of the ongoing revolutions are expected to change professions and working cultures deeply, perish some occupations and bring new ones into daylight. International Federation of Surveyors is a well-established society, which is aware of this wave of change approaching for a long period. This issue has been addressed in many events of the FIG, Commissions and Young Surveyors Network. To contribute these efforts, the new working group will maintain the link with the changing role of surveyor in the society based on the near future geospatial technologies and next generations within the scope of the Commission 3 Spatial Information Management. The working group should be considered as a respond to contribute to the technological and organizational skills for the changing needs of the surveyors to exist in the dawn of the new industrial era and produce together with inter generations of geospatial professionals in Commission 3. Therefore, this working group will be able to work with various professional level groups together with the other Com. 3 Working Groups where it is possible. Chair Cemal Özgür Kivilcim, Turkey
