Full textThe European Mediterranean coastal area has experienced widespread land cover change since 1950 because of rapid urban growth and expansion of tourism. Urban sprawl and other land cover changes occurred due to post-war economic conditions, population migration, and increased tourism. Land cover change has occurred through the interaction of environmental and socio-economic factors, including population growth, urban sprawl, industrial development, and environmental policies. In addition, rapid expansion of tourism during the last six decades has caused significant socioeconomic changes driving land cover change in Euro-Mediterranean areas. Mediterranean countries from Spain to Greece experienced strong urban growth from the 1970’s onwards, and a moderate growth rate is projected to continue into the future. Land cover change can result in environmental changes such as water pollution and soil degradation. Several previous studies have shown that Mediterranean vineyards are particularly vulnerable to soil erosion because of high rainfall intensity and the fact that vineyards are commonly located on steeper slopes and the soil is kept bare during most of the cultivation period (November to April) when precipitation is at its highest. The main objective of this thesis is to predict long-term soil erosion evolution in a Mediterranean context of rapid urban growth and land use change at the catchment scale. In order to achieve this, the following specific aims have been formulated: (i) to analyze the spatial dynamics of land cover change from 1950 to 2008; (ii) to compare the impact of historical time periods on land cover prediction using different time scales; (iii) to test the impacts of spatial extent and cell size on LUCC modeling; and (iv) to predict the impact of land cover change on soil erosion for 2025

Full textSince 2007, the launch of fully polarimetric SAR sensors has significantly improved the potential of satellite SAR data for the vegetation cartography. These sensors allow to make a complete description of the polarization state of the backscattered wave whatever the polarization configuration of the incident wave. Polarimetric data are sensitive to the geometrical structure of the vegetation cover, bringing a significant contribution for vegetation cartography. Different fully polarimetric sensors have been launched since 2007: ComoSkyMed, RADARSAT-2, and PALSAR sensors allowing observations in X, C, and L bands, with spatial resolution ranging from 1 to 30 m. Pilote sites are French Guiana (French) and Ivory coast (West African country) in humid tropical zone. In French Guiana, many studies in the past years guarantee a rich and detailed geographical knowledge, our works concern the multi parameters radar image analysis method (wavelength, polarization, resolution) and their exploitation together with external mapping data in the aim of implementing the temporal survey of the locally encountered environment (dense forest, coastal plains, mangrove forests, wetlands,…). In fact, with 80% of forest cover, French Guyana needs an update of existing cartographic documents to quantify the evolution of his dynamic vegetation. Once this assessment made on the Guyana was detailed and argued, the researches will concern to test zones in Ivory Coast which contrary to the Guyana, do not have geographical quality knowledge but where the tropical climate makes the use of radar images necessary as in Guyana. The first chapter of this work describes the fields met on our areas of study as well as the data available on each of them. Second chapter focuses on the methodology of processing and analysis of multicriterias radar images and their joint exploitation with optical images of very high-spatial resolution. Then, two approaches of evaluation of the images are discussed. A first approach, based on photo-interpretation, relies on the existing cartographic documents and on the land surveys to estimate visually the images. A second approach stating the evaluation thanks to the supervised classification for which two techniques were used: the SVM classification and the object-oriented classification. The third chapter is dedicated to the thematic applications of images on the test areas situated in French Guyana and in Ivory Coast. The mapping of the land use, the follow-up (survey) of the littoral wetlands and the coastal dynamics, all these applications can lead to the update of the existing cartographic documents

Full textSince 1999, Very High spatial Resolution satellite data (Ikonos-2, QuickBird and OrbView-3) represent the surface of the Earth with more detail. However, information extraction by multispectral pixel-based classification proves to have become more complex owing to the internal variability increase in the land-cover units and to the weakness of spectral resolution.
Therefore, one possibility is to consider the internal spectral variability of land-cover classes as a valuable source of spatial information that can be used as an additional clue in characterizing and identifying land cover. Moreover, the spatial resolution gap that existed between satellite images and aerial photographs has strongly decreased, and the features used in visual interpretation transposed to digital analysis (texture, morphology and context) can be used as additional information on top of spectral features for the land cover classification.
The difficulty of this approach is often to transpose the visual features to digital analysis.
To overcome this problem region-based classification could be used. Segmentation, before classification, produces regions that are more homogeneous in themselves than with nearby regions and represent discrete objects or areas in the image. Each region becomes then a unit analysis, which makes it possible to avoid much of the structural clutter and allows to measure and use a number of features on top of spectral features. These features can be the surface, the perimeter, the compactness, the degree and kind of texture. Segmentation is one of the only methods which ensures to measure the morphological features (surface, perimeter.) and the textural features on non-arbitrary neighbourhood. In the pixel-based methods, texture is calculated with mobile windows that smooth the boundaries between discrete land cover regions and create between-class texture. This between-class texture could cause an edge-effect in the classification.
In this context, our research focuses on the potential of land cover region-based classification of VHR satellite data through the study of the object extraction capacity of segmentation processes, and through the study of the relevance of region features for classifying the land-cover classes in different kinds of Belgian landscapes; always keeping in mind the parallel with the visual interpretation which remains the reference.
Firstly, the results of the assessment of four segmentation algorithms belonging to the two main segmentation categories (contour- and region-based segmentation methods) show that the contour detection methods are sensitive to local variability, which is precisely the problem that we want to overcome. Then, a pre-processing like a filter may be used, at the risk of losing a part of the information. The “region-growing” segmentation that uses the local variability in the segmentation process appears to be the best compromise for the segmentation of different kinds of landscape.
Secondly, the features calculated thanks to segmentation seem to be relevant to identify some land-cover classes in urban/sub-urban and rural areas. These relevant features are of the same type as the features selected visually, which shows that the region-based classification gets close to the visual interpretation.
The research shows the real usefulness of region-based classification in order to classify the land cover with VHR satellite data. Even in some cases where the features calculated thanks to the segmentation prove to be useless, the region-based classification has other advantages. Working with regions instead of pixels allows to avoid the salt-and-pepper effect and makes the GIS integration easier.
The research also highlights some problems that are independent from the region-based classification and are recursive in VHR satellite data, like shadows and the spatial resolution weakness for identifying some land-cover classes.
Résumé
Depuis 1999, les données satellitaires à très haute résolution spatiale (IKONOS-2, QuickBird and OrbView-3) représentent la surface de la terre avec plus de détail. Cependant, l’extraction d’information par une classification multispectrale par pixel devient plus complexe en raison de l’augmentation de la variabilité spectrale dans les unités d’occupation du sol et du manque de résolution spectrale de ces données. Cependant, une possibilité est de considérer cette variabilité spectrale comme une information spatiale utile pouvant être utilisée comme une information complémentaire dans la caractérisation de l’occupation du sol. De plus, de part la diminution de la différence de résolution spatiale qui existait entre les photographies aériennes et les images satellitaires, les caractéristiques (attributs) utilisées en interprétation visuelle transposées à l’analyse digitale (texture, morphologie and contexte) peuvent être utilisées comme information complémentaire en plus de l’information spectrale pour la classification de l’occupation du sol.
La difficulté de cette approche est la transposition des caractéristiques visuelles à l’analyse digitale. Pour résoudre ce problème la classification par région pourrait être utilisée. La segmentation, avant la classification, produit des régions qui sont plus homogène en elles-mêmes qu’avec les régions voisines et qui représentent des objets ou des aires dans l’image. Chaque région devient alors une unité d’analyse qui permet l’élimination de l’effet « poivre et sel » et permet de mesurer et d’utiliser de nombreuses caractéristiques en plus des caractéristiques spectrales. Ces caractéristiques peuvent être la surface, le périmètre, la compacité, la texture. La segmentation est une des seules méthodes qui permet le calcul des caractéristiques morphologiques (surface, périmètre, …) et des caractéristiques texturales sur un voisinage non-arbitraire. Avec les méthodes de classification par pixel, la texture est calculée avec des fenêtres mobiles qui lissent les limites entre les régions d’occupation du sol et créent une texture interclasse. Cette texture interclasse peut alors causer un effet de bord dans le résultat de la classification.
Dans ce contexte, la recherche s’est focalisée sur l’étude du potentiel de la classification par région de l’occupation du sol avec des images satellitaires à très haute résolution spatiale. Ce potentiel a été étudié par l’intermédiaire de l’étude des capacités d’extraction d’objet de la segmentation et par l’intermédiaire de l’étude de la pertinence des caractéristiques des régions pour la classification de l’occupation du sol dans différents paysages belges tant urbains que ruraux.

Full textFor political or environmental matters, land cover mapping has become more and more important since the beginning of the XXIst century. This mapping consists in, given a set of land cover classes, classifying ground-level objects according to these classes. Adressing very various applications, from a local scale (city-wise) to a more global scale (world-wide), several projects have been initiated so as to build land cover maps that would fit one of these applications. However, the current means to achieve this mapping are mainly manual, leading to high cost of production both in terms of man power and processing time. The task of building relevant land cover maps lies also in being able to monitor various phenomena in time, but acquiring data can be expansive for frequent updates or computation of maps at large scale. Yet, remote sensors have multiplied for the past two decades and the panel of such sensors is very wide and diverse in a spectral way and in terms of resolution. Among them, optical sensors boarded on Earth observation satellites acquire images in the visible and infrared spectrums, with high revisit time capabilities. SPOT 6 and 7 were launched in 2012 and 2014 respectively, and offer very high resolution images at 1.5m, in four bands. The French Mapping Agency computes each year a full France coverage from the SPOT data available through the THEIA data portal. Although this task has been widely studied in the past by the remote sensing community, by the means of supervised classifiers such as SVMs or random forests, none of the results have yet led to truly automated and satisfying maps that match existing specifications due to mislabelling errors that occur too often. In terms of methodology, the deep learning, and more specifically deep neural networks have proved to be far more efficient than other machine learning algorithms in various fields of research, from computer vision to natural language processing and system recommendation. These days, deep learning has become a part of everyday life, not only for academic research purposes, but also it society where it runs in the background of our smartphones for various tasks. Such ubiquity raises ethical issues: in particular, users’ browsing habits and behaviours are often monitored without them knowing to feed these algorithms. This heavy need for data is what allows deep learning to sketch more accurately a user behaviour, thus leading to more suitable commercial offers based on a history of purchases for instance.In our work, the French Mapping Agency topographic databases represent a real opportunity to massively train deep neural networks on the SPOT monoscopic very high resolution images, so as to produce land cover maps. The works reported in this dissertation are focused on this problematic of land cover mapping with deep neural networks on SPOT 6 and 7 data, with the additional constraint of tackling this task in a more general operational environment (large scale land cover mapping). This latter point ensures that the conducted experiments address occurring questions when classifying large geographic areas. For instance, a specific SPOT coverage is made of one image per territory, which means adjacent areas can have been acquired at different dates, leading to strong appearance discrepancies. Transfer learning is a tool that can help a lot in lots of scenarii so as to reduce both time computation and needs for training samples. Finally, in a context of the automatic update or re-computation of existing topographic database, the use of aerial images in deep neural networks is assessed in several tasks, with an emphasis on the training dataset conception from topographic database that can include some drawbacks

Full textMost important cities in the world have very detailed 2D urban plans of streets and public spaces.These plans contain information about roads, sidewalks, facades and urban objects such as lampposts, traffic signs, bollards, trees, among others.Nowadays, several local authorities, national mapping agencies and private companies have began to consider justifiable including 3D information, navigation options and accessibility issues into urban maps.Compared to the first 3D scanning systems 30 years ago, current laser scanners are cheaper, faster and provide more accurate and denser 3D point clouds.Urban analysis from these data is difficult and tedious, and existing semi-automatic methods may not be sufficiently precise nor robust.In that sense, automatic methods for 3D urban semantic analysis are required.This thesis contributes to the field of semantic analysis of 3D point clouds from urban environments.Our methods are based on elevation images and illustrate how mathematical morphology can be exploited to develop a complete 3D processing chain including six main steps:i)~filtering and preprocessing;ii)~ground segmentation and accessibility analysis;iii)~facade segmentation,iv)~object detection;v)~object segmentation;and, vi)~object classification.Additionally, we have worked on the integration of our results into a large-scale production chain. In that sense, our results have been exported as 3D point clouds for visualization and modeling purposes and integrated as shapefiles into Geographical Information Systems (GIS).Our methods have been qualitative and quantitative tested in several databases from the state of the art and from TerraMobilita project.Our results show that our methods are accurate, fast and outperform other works reported in the literature on the same databases.Conclusions and perspectives for future work are discussed as well
