[Termes IGN] zone urbaineRésumé : (auteur) In this paper, we address tree segmentation and localization in the scope of the IQmulus Processing Contest IQPC’15. Based on the part of pre-classified 3D point cloud data which corresponds to trees, we present a novel framework which involves a downsampling of the original data, a projection of the downsampled data onto a horizontally oriented plane, a mean-shift-based segmentation of the projected points, a transfer of the segmentation results to the original data, a refinement of the segmentation results via segment-based shape analysis, and a localization of respective tree trunks. The results derived for a benchmark dataset reveal that all individual trees are correctly detected and localized with both acceptable accuracy and reasonable computational effort.

[Termes IGN] zone urbaineRésumé : (auteur) The design of documents impacting potential new constructions, such as Right to Build plans, is a complex issue. New tools need to be proposed in order to systematically assess the impact of regulations on the building potential of the concerned areas. Furthermore, it is often not directly the morphology of new constructions that administrations and citizens would like to regulate but their properties with regard to other phenomena (solar energy potential, etc.). In order to tackle these issues, we propose in this article to explore building configurations and regulations using a stochastic building generator and a workflow engine. The workflow we propose for such an exploration will produce important amounts of data that we intend to release as OpenData in order for administrations, urban planners and citizens to be able to freely visualize and collectively choose the regulations that best suit their territory. Such amount of 3D geographical data also suggests new issues in geovisualization.

[Termes IGN] zone urbaineRésumé : (auteur) This proposal consist in presenting the process which is leading to the implementation and exchanges of “Very large scale core street map” in France between networks operators (power, gas and public lightning) and local authorities, so as to prevent damages on underground pipelines during pipe-works. For local authorities and State relevant administrations, the accurate knowledge of the underground pipeline network is fundamental. Yet now, most of the time, they only arrange with cartographic plans coming from diverse sources, without consistency of scale, and with different quality of accuracy, what harms in the design of projects and expose to risks during the pipe-works. In 2012, a reform came into force, from then the contracting authorities are responsible of pipe-works’ security, the networks operators have to commit on their pipe-networks’ location, the public works companies have to give evidence of skills bound to the works they execute. The objectives are to improve the accuracy of the pipe-networks location and enhance reliability of the geo information exchanges between stake-holders. In 2019, the gas, power and lightning underground networks in urban areas will have to be georeferenced in the national system of coordinates with 40 cm accuracy. In 2026, these requirements will be applicable for all the networks in France. The reform involves local authorities and networks operators to use the same shared data to locate the underground pipe-networks: the “Very large scale core street map” designed by the stake-holders themselves within the frame of the French national council for geographic information (CNIG) in 2015. Actuality, stake-holders are steadily meeting within the CNIG to accompany the nation-wide implementation of the “Very large scale core street map”: rural areas, local agreements and technical choices are still important issues.

[Termes IGN] zone urbaineRésumé : (auteur) Geospatial techniques based on remote sensing and geographic information system (GIS) are important in urban studies. However, based on traditional techniques, the analysis of the intensity ans spatial pattern of urban land use is, in most cases, based only on the lateral extent of built-up lands (two-dimensional). The increasing availability of geospatial data, such remote sensing satellite imageries and digital surfaces models, provides an opportunity for the integration of the third dimension in urban analysis, i.e. height of urban features such as high-rise buildings, into urban studies, and thus enables the estimation of the so-called urban volume. This study introduces a geospatial technique for estimating urban volume, focusing on the use of a digital surface model (DSM) derived from Alos PRISM data. It also presents a method for deriving a digital terrain model (DTM) from a DSM. The proposed technique was tested in Makati City, Metro Manila, Philippines. Overall, the results show that the proposed technique is capable of taking into consideration the height dimension in urban analysis. The proposed two-step grid-based method for deriving a DTM from DSM is also implementable and promising. In this method, there is a need to calibrate the size of the mesh for identifying the pixels or points to be used in DTM interpolation. This is because different mesh size can produce subtantially different DTMs, suface feature height values and urban volumes estimates.
