2 Origins M. Laurent Niggeler, géomètre cantonal, Geneva, Switzerland Research mandated by the Swiss Conference of Cadastre Services (KKVA) Cadastre 2014, J. Kauffman and D. Steudler, FIG 7, 1998 Work in progress by Xavier Comtesse and myself Giorgio Pauletto has studied economics and quatitative methods in Geneva, he has a masters degree from Stanford University in Management Science and Engineering and obtained his doctorate at the Department of Econometrics of the University of Geneva in He was a visiting fellow at the Hoover Institution at Stanford (1997) and at Yale (1998). He works as a technology and strategy advisor for the State of Geneva in Switzerland. He helps the development of prospective views and he articulates them into the public sector.

5 Thesis 1: The cadastre will include the third dimension of the landscape and of the objects beyond the current legal framework. Comment: The technology allows a thorough three dimensional vision of the land. This is now integrated in several products largely distributed by companies such Google and ESRI but also Nokia, Microsoft and several others. This paradigm change raises the issue of height, ownership and that of co-ownership (e.g. several owners of the different levels in buildings) and the rights attached to the third dimension such as for example the right to a view. Consequence: A new 3D model of the land and of the buildings is necessary and land surveyors have to take 3D into account. 5

9 Thesis 2: The cadastre will blend the strategic map and the dynamic map of the land to show its historical evolution. Comment: The push of technology makes it possible to store the information with different time stamps instead of erasing or superseding it. An animation of the evolution of an object or a region becomes possible by adding the dimension of time. Spatio Temporal Object Model: Each object has an attribute of time. Consequence: The current separation between the static object and the dynamic object will be deeply transformed. A static object becomes a snapshot at a given moment of its dynamic version. Each object carries information about its history and the geographical information system integrates time as a variable. 9

11 Thesis 3: The cadastre will be multifunctional and multijurisdictional. Comment: The political as well as the technological influence foster the emergence of functions of a territory. Different regions can be viewed not only as jurisdictions, but also through the lens of different functions such as the environmental function, the transportation function, etc. It therefore will be possible to assess the impact of policies on different functions and to create many functional approaches to the territory. Moreover, the interoperability between various local cadastres will render a change of function possible upon request. Consequence: The local cadastres will be blended into larger ones and include not only jurisdictional views but also functional views. 11

14 Thesis 4: Social networks will transform the cadastre. Comment: The phenomenon of georeference by the public becomes a more and more normal and accepted tool to extend the cadastre. Almost all new moving devices include GPS chips (smartphones, cameras, cars, even cattle!) that can report flows of data. This allows to georeference the objects and their surroundings in a completely new way. Consequence: The cadastre will deal more with flows of data and less with stocks of data. 14

16 An elephant path is a trail developed by erosion caused by people making their own shortcuts (a phenomena we love to observe). The Elephant Path application reveals unofficial routes and beaten tracks from the the thousantds of pieces of information inhabitants and visitors of a region share publicly online. It uses social navigation mechanisms that rely on the activity of groups of people to propose and suggest movements towards active places. 16

17 Thesis 5: New commons will emerge as a referenced object of the cadastre. Comment: Data will be more and more made available to the general public by the administration and, through mash-up techniques, will be transformed into a new virtual object the «Common Good». This new object is a composition of several layers of data and services. It will create value and be used as a global public good. Consequence: Both the private and the public sectors will gain added value by leveraging the these new commons. As it is mainly composed of information, the resource is essentially non-rivalrous (consumption by one person doesn t prevent simultaneous consumption by another) and non-excludable (it is difficult if not impossible to prevent someone to have access). 17

18 Entering the search term Rome on Flickr returns more than two million photographs. This collection represents an increasingly complete photographic record of the city, capturing every popular site, facade, interior, fountain, sculpture, painting, cafe, and so forth. It also offers us an unprecedented opportunity to richly capture, explore and study the three dimensional shape of the city. In this project, we consider the problem of reconstructing entire cities from images harvested from the web. Our aim is to build a parallel distributed system that downloads all the images associated with a city, say Rome, from Flickr.com. After downloading, it matches these images to find common points and uses this information to compute the three dimensional structure of the city and the pose of the cameras that captured these images. All this to be done in a day. 18

19 Thesis 6: The cadastre will become an essential element of knowledge society. Comment: The cadastre follows the same path as society as it evolves from an information society to a knowledge society. This is seen through the addition of georeference to many human activities, the emergence of co-creation by entire crowds, and the body of knowledge that the cadastre carries enters more and more into models and decisions. The objects of the cadastre will be part of a feedback loop that makes its way into knowledge society. Consequence: Land surveyors will be dealing more with soft fields of knowledge rather than hard science in the future. 19

20 Visualizing OpenStreetMap updates during OpenStreetMap is a wiki-style map of the world and this animation produces a flash of white each time a new way is entered or when an existing way is updated. Some edits are a result of a physical local survey by someone with a GPS unit, other edits will have been done remotely using aerial photography or out-of-copyright maps. Others are based on bulk imports of official or commercial datasets that are available using a suitable 'share-alike' licence. OpenStreetMap started in 2004 and the rate of contributions has been accelerating with four times as many people contributing to the project in 2008 compared to 2007 and with bulk imports of data for the Belarus, India, Italy, USA and for many other places. Supporting OpenStreetMap is an important part of ITO's business which is focused on providing high-quality on-line transport and mapping services to both organisations and individuals in the UK and around the world. 20

21 OpenStreetMap - Project Haiti With the little existing physical, political and social infrastructure now destroyed or damaged, the situation was especially challenging for aid agencies arriving on the ground. Where are the areas most in need of assistance, how do we get there, where are people trapped under buildings, which roads are blocked? This information is important to the rescue agencies immediately after the event, and to the longer rebuilding process. In many developing countries, there is a lack of good mapping data and particularly after a crisis, when up-to-date information is critical to managing events as they evolve. Enter OpenStreetMap, the wiki map of the world, CrisisMappers and an impromptu community of volunteers who collaborated to produce the most authoritative map of Haiti in existence. Within hours of the event people were adding detail to the map, but on January 14th high resolution sattelite imagery of Haiti was made freely available and the Crisis Mapping community were able to trace roads, damaged buildings, and enter camps of displaced people into OpenStreetMap. This is the story of OpenStreetMap - Project Haiti: Each flash represents a new edit into OpenStreetMap, and this visualisation is a vivid picture of how much work was contributed by volunteers, following the quake. First the primary and secondary roads (green and red) are added and then smaller residential streets and many other features such as the blue glowing camps of displaced people that emerge. 21
