Un large éventail de méthodes de traitement automatique d'images aériennes a été proposé depuis plusieurs années pour la reconstruction 3D d’environnements urbains. Ces approches sont aussi nombreuses que variées, tant en ce qui concerne le type de données utilisées que sur le plan du degré d'automatisation de la méthode. Cependant, la plupart des modélisations se limitent aux objets créés par l'homme (bâti, route...). Or la végétation est également très importante pour la compréhension des zones urbaines. Les modèles urbains 3D peuvent être améliorés par l’intégration de la végétation, avec une description précise de la disposition des arbres et des espèces. Cette thèse présente le développement d’un système hiérarchique d'analyse d'images aériennes couleur et infrarouge pour la détection et la caractérisation de la végétation en vue de la modélisation 3D des milieux urbains. Le premier module de ce système a pour fonction de détecter les zones de végétation. L’approche adoptée repose sur une méthode de classification supervisée utilisant les Séparateurs à Vaste Marge (SVM) que nous comparons aux approches traditionnelles de télédétection. Les modules suivants ont pour but de caractériser ces zones de végétation. La séparation en végétation haute (arbre) et végétation basse (pelouse) repose sur un critère de texture calculé sur le modèle numérique de surface (MNS). Ensuite, une étape d'extraction de houppiers faisant intervenir un algorithme de croissance de régions intégrant des caractéristiques géométriques d’arbres est présentée. Des paramètres morphologiques (la hauteur, le diamètre de la couronne, la localisation du tronc des arbres) sont estimés pour chaque houppier. Les différentes espèces d’arbres sont ensuite déterminées par un système de classification supervisée. Dans ce domaine, nous avons étudié l’apport des caractéristiques radiométriques, de texture, ainsi que de leur fusion. L'ensemble des informations extraites par ce système (paramètres morphologiques, type de végétation et espèce) est utilisé pour enrichir un modèle 3D urbain avec des modèles de végétation réalistes.

[Termes IGN] photogrammétrie aérienneRésumé : (Auteur) 1- In the past few years, the production of 2D topographic databases has been completed in most industrialised countries. Presently, most efforts in the National Mapping and Cadastral Agencies (NMCAs) are devoted to the update of such databases. Because the update process is generally carried out manually by visual inspection of orthophotos, it is time-consuming and expensive. The development of semi-automatic systems is, thus, of high interest for NMCAs. The current deficits in automation and the lack of expertise within NMCAs have driven the EuroSDR (European Spatial Data Research) to launch a project in this topic. The aim of the project "Detection of unregistered buildings for updating 2D databases" is to evaluate the feasibility of semi-automatically detecting changes in a 2D building vector database from optical imagery or LIDAR. Three specific sub-topics are investigated in detail: firstly, the impact of methodology; secondly, the impact of the type and spatial resolution of input data; lastly, the impact of the complexity of the scene, especially with respect to topography and land use. A comparison of algorithms representative of the current state-of-the-art in the field of change detection is performed. In this report, we describe the three test areas used in the project, the methodology used for assessing and comparing the methods, and the results that have been obtained with the four different approaches. The results are thoroughly analysed and a discussion enables to bring out conclusions and promising directions to follow for building an optimal operational system in the future. 2- This final report of the EuroSDR project "NEWPLATFORMS" gives an overview of a very promising new class of platforms for remote sensing, unmanned aircraft systems or UAS. Although unmanned aircraft have been around for many years, they are now becoming available for scientific and civil use, as low-altitude systems that provide an "eye in the sky" for small photogrammetry projects (the size of a construction site), and for the development of new remote sensing applications. First, the concept of an UAS is described. It is not just about the aircraft, but also about its ground control system (which gives the remote pilot the ability to control the aircraft). Two ways of classification are given, one more descriptive (based on physical properties such as total mass, range, endurance, etc.), and one based on the flight clearance potential. The latter is important, since there is a total lack of coherent regulations across Europe. A summary of the regulatory authorities is presented in chapter 2. The report concludes with a review of the (potential) applications in remote sensing that can be conducted with UAS.

Potential readers/users are students of Photogrammetry, Geodesy, Geography and other sciences, but also all who are interested in this topic. No prior knowledge is necessary, except the handling of standard PCs. Theory is presented true to the motto "as little as possible, but as much as necessary". The main part of the book contains several tutorials. In increasing complexity, accompanied by texts explaining further theory, the reader can proceed step by step through the particular working parts. All intermediate as well as the final results are discussed with reference to accuracy and error handling. Most of the standard work in Digital Photogrammetry is shown and trained for example scanning, image orientation, mono and stereo plotting, aerial triangulation measurement (manual and automatic), block adjustment, automatic creation of surface models via image matching, creation of ortho images and mosaics, and others. Not only standard situations are dealt with but also more complex ones, such as unknown camera data, extreme relief or areas with very low contrast. Examples of both aerial and close-range photogrammetry present the power of these type of measurement techniques. The software is not limited to the example data included but may be used for personal projects. Part of the book comprises a complete description of the software. Note de contenu : 1 Introduction

[Termes IGN] visualisation 3DRésumé : (Auteur) This dissertation results from the work conducted by the author within the frame of the Nasca-Palpa project at the chair of photogrammetry and remote sensing of ETH Zurich. The work presented here reports on the work conducted at ETH Zurich during the Nasca/Palpa project with the focus on the investigation of the geoglyphs, also known as the Nosca lines, in the Palpa area. This thesis covers basically two main parts: Photogrammetric data acquisition, processing and geoglyph reconstruction for the Palpa region and the Pampa de Nasca and CIS-based management and analysis of the generated data, primarily for the geoglyphs of Palpa. The motivation behind this work was the need for suitable data management and analysis methods demanded by the involved archaeologists to enable a quantitative study of the spatial characteristics of the geoglyphs and the surrounding landscape in order to better understand the social and cultural meaning of the geoglyphs. Aside from the geoglyphs, a second class of figurative remains was investigated: The petroglyphs of Chichictara.
Complementary to the archaeological investigations of our project partners, namely the German Archaeological Institute (DAI-KAAK), Bonn, Germany), the author concentrated on methods for 3D data acquisition for archaeological purposes in large and medium scale with the focus on photogrammetric methods. Furthermore, a second important focus was laid on the design of a GIS database containing archaeological and spatial information and the development of analysis methods with respect to the spatial characteristics of the archaeological objects to be investigated, in this case the geoglyphs in the Nasca region and the petroglyphs of Chichictara in south Peru. The accomplished work resulted in a wide variety of data and derived products and analysis results which led to new insights in the historical function and meaning of the geoglyphs of Nasca. The generated data consists of Digital Terrain Models derived from aerial and satellite imagery, 3D vector data representing the geoglyphs, high resolution orthoimages and numerical results of analyses performed based on the generated spatial data.
The applied and developed methods aim to investigate the geoglyphs in a manner that should be as objective as possible, trying to answer concrete archaeological questions. Though manifold hypotheses on the geoglyphs exist, the aim was not to focus on a single one but given the data available to investigate especially those which imply a spatial character for the subset of geoglyphs of Palpa. The methods applied for data acquisition, object definition and quantitative analysis of the geoglyphs are an important achievement of this thesis and can be applied in future studies on more complete sets of geoglyph data as well as for similar studies in other areas of investigation. Analogue to the development of the GIS database for the geoglyphs, a database for petroglyph data was developed under consideration of the true 3D character of this rock art and its surrounding topography. The developed databases, tools and analysis methods described here represent a system that is suited as a basis for archaeological interpretation of the landscape decorations in the Nasca and Palpa region and provides even an enormous potential for further analyses to be accomplished in the future. At the present state, the database contains data on the geoglyphs of Palpa and of a subset of the petroglyphs at Chichictara. though the developed data structure enables an enhancement with further data on both, Nasca time geoglyphs and Paracas time petroglyphs, from other sites. Having these two valuable databases documenting the two classes of figures that engrave the landscape in such an impressive way, a wide range of possibilities of archaeological interpretation opens up for future work beyond this thesis, as well do the developed tools and methods presented here.
The author thanks the Swiss-Liechtenstein foundation for Archeological Research Abroad (SLSA), the AVINA foundation and ETH Zurich for their valuable support that enabled this thesis.Note de contenu : 1 Introduction
