[Termes IGN] programmation par contraintesRésumé : (Auteur) New, free and fast growing spatial data sources have appeared online, based on Volunteered Geographic Information (VGI). OpenStreetMap (OSM) is one of the most representative projects of this trend. Its increasing popularity and density makes the study of its data quality an imperative. A common approach is to compare OSM with a reference dataset. In such cases, data matching is necessary for the comparison to be meaningful, and is usually performed manually at the data preparation stage. This article proposes an automated feature-based matching method specifically designed for VGI, based on a multi-stage approach that combines geometric and attribute constraints. It is applied to the OSM dataset using the official data from Ordnance Survey as the reference dataset. The results are then used to evaluate data completeness of OSM in several case studies in the UK.

[Termes IGN] reliefRésumé : (Auteur) User generated content such as the georeferenced images and their associated tags found in Flickr provides us with opportunities to explore how the world is described in the non-scientific, everyday language used by contributors. Geomorphometry, the quantitative study of landforms, provides methods to classify Digital Elevation Models (DEMs) according to attributes such as slope and convexity. In this article we compare the terms used in Flickr and Geograph in Great Britian to describe georeferenced images to a quantitative, unsupervised classification of a DEM, using a well established method, and explore the variation of terms across geomorphometric classes and space. Anthropogenic terms are primarily associated with more gentle slopes, while terms which refer to objects such as mountains and waterfalls are typical of steeper slopes. Terms vary both across and within classes, and the source of the user generated content has an influence on the type of term used with Geograph, a collection which aims to document the geography of Great Britain, dominated by features which might be observed on a map.

[Termes IGN] représentation cartographiqueRésumé : (Auteur) Maps provide an effective means of distributing ideas simply, creating a format where spatial data can be easily understood. However, a lot of people are not aware where administrative boundaries lie, limiting their appeal for educating the public on important issues such as poverty and inequality. This paper seeks to utilize a well-known cartographic map design, the London Underground map, to aid data dissemination of the complex issues surrounding inequality and deprivation in London. A discussion of the relevance of this approach to researching inequality in London, as well as how this fits in with previous approaches to mapping poverty is provided. An example using the recent release of the Indices of Multiple Deprivation 2010 shows the usefulness of this design.

[Termes IGN] zone urbaineRésumé : (Auteur) A near real-time flood detection algorithm giving a synoptic overview of the extent of flooding in both urban and rural areas, and capable of working during night-time and day-time even if cloud was present, could be a useful tool for operational flood relief management. The paper describes an automatic algorithm using high-resolution synthetic aperture radar (SAR) satellite data that builds on existing approaches, including the use of image segmentation techniques prior to object classification to cope with the very large number of pixels in these scenes. Flood detection in urban areas is guided by the flood extent derived in adjacent rural areas. The algorithm assumes that high-resolution topographic height data are available for at least the urban areas of the scene, in order that a SAR simulator may be used to estimate areas of radar shadow and layover. The algorithm proved capable of detecting flooding in rural areas using TerraSAR-X with good accuracy, classifying 89% of flooded pixels correctly, with an associated false positive rate of 6%. Of the urban water pixels visible to TerraSAR-X, 75% were correctly detected, with a false positive rate of 24%. If all urban water pixels were considered, including those in shadow and layover regions, these figures fell to 57% and 18%, respectively.
