The humble pie chart, the basic line graph: we are used to these and other forms of basic graphs. These have become commonplace and they can blend into the background, another plot on the screen real estate that accompanies our lives. To stand out, screen based data visualizations have become ever more beautiful, intricate and bespoke, but in so doing their legibility can suffer. In a project on community data, run in collaboration with residents of Tenison Road in Cambridge, we have been exploring how to present data to the community that will be accessible to as many local people as possible. We chose to use our highly visible window-frontage, visible from Tenison Road itself. As a technology company, our street facing window is full of screens, which could easily have been used for our purposes. Instead we have designed and built physical visualizations of a pie chart and a line graph. These are simple in the sense that they are easy to read and make playful use of some readily available material (like retractable tape measures). Their design is sensitive to the need for readability and spectacle.

In addition to being more memorable than tables, graphics can also illustrate multiple dimensions and important relationships far better than tables. Edward Tufte says it best (6): "Modern data graphics can do much more than simply substitute for small statistical tables. At their best, graphics are instruments for reasoning about quantitative information. Often the most effective way to describe, explore, and summarize a set of numberseven a very large set-is to look at pictures of those numbers. Furthermore, of all methods for analyzing and communicating statistical information, well-designed data graphics are usually the simplest and at the same time the most powerful. " In this paper I highlight some of the best plots published in AJG in the past year, show some graphics that could be improved, and illustrate how perhaps one plot could convey information more directly than a table.

Over the last 15 years or so, a number of political, economic, environmental and social factors as well as the rapid technological innovation have profoundly changed the outlook for good management of land, the sea and especially the built environment. In this context, the issue of security of tenure and registration of property rights is recognized as an increasingly important component for eliminating poverty and achieving sustainable development of land, real estate and property markets in all UN member states, particularly in urban areas. In view of the Sustainable Development Agenda 2030 all UN member states are developing and modernizing their cadastre and land registration systems and in parallel formalizing their property markets. Present land administration systems and cadastres need re-engineering; they must continually evolve to cope with the ongoing megatrends, such as urbanization, demographic change, societal disparities, the digital transformation, volatile global economy, anthropogenic environmental damage and so on. Much of the current research by the surveying profession in this field focuses on issues related to 3D geo-information, tools for data collection, cloud solutions, data management, optimizing processes and web-based information dissemination; standardization of 3D information, advanced modelling and visualization, as well as formalizing and building sustainable real estate markets as a pillar for robust economic urban growth; and related policies, legal and institutional aspects and knowledge sharing in operational experiences, the emerging challenges and the good practices. The significance of these areas of interest for the good management of land, the sea and especially the built environment is well understood. It is mainly about people and their living in urban settlements. It is mainly about developing the "cities we want", digitally networked and intelligent. And 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. For our young readers let me give some impressive information. A mega city is an urban area of 10 million population or more. The Economist "Pocket World in Figures" 2016 Edition, lists thirty-three mega cities of the world from Bangalore, India at ten point one million, thirty-third on the list, to number one Tokyo at thirty-eight million. The World Health Organization (WHO) has reported that in 2014 fifty-four percent of the world's people lived in urban areas, up from thirty-four percent in 1960. The tipping point, according to most authorities, occurred in 2007 when there were more urban dwellers than rural residents in the world: the so-called "urban millennium." The United Nations predict that by 2050 sixty-six percent of the world's population will live in urban areas. VI FIG publication Best Practices 3D Cadastres-Extended version Much is being written about the growth of urban populations and the concurrent growth of urban infrastructures and institutions to support this huge growth of two-thirds of the world's people in the cities. Of all the institutions that must be developed to anticipate, keep abreast of and support this growth, the cadaster stands foremost in the interest of commerce, real estate investment, municipal revenue, and personal property security, not to mention urban planning and management. As the 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 cadaster concept, by adding the time dimension and the detail/scale dimension to the equation. In a discussion of "cost effectiveness" one must consider time, that 4 th 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 cadaster, 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 and the need for continuing research on fundamental policy issues of technical administrative, legal and financial aspects of land administration. This publication is a further contribution of FIG in this ongoing process of improving land administration systems. 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. This study takes into account the recent developments that have taken place, and I hope that it will lead to a better understanding of the concept of a 3D cadaster.
