Full text@Whatever the field studying territories and spaces, the notion of scale is at the center of researches. Though it is very familiar to geographers, it reveals all its complexity in studies made in Remote Sensing. When considering the notions of EIFOV and complementarity between sensor system, researches are carried out about determination of the " limit spatial resolution ", beyond which point information cannot be used any more. So, researches are done about an area presenting a landscape heterogeneity that can be read on different spatial scales so as to make this concept valid. Prior to any study, it is essential to think about the structure of the landscape that is being studied and the precision of the expected nomenclature as well as the availability of Remote sensing data and terrain data, guarantees of an optimum identification of land cover. As spatial analyses at a given date have revealed how limited the determination of land cover was regarding both quantification and precision, temporal analyses have been thought of to solve these problems. This conceptual method has found its application on the demonstration watershed of the " Drains de Rennes I ", within the context of the program of action " Bretagne Eau Pure " relative to the reconquest of the quality of water

Full textAt the present time, some programmes are carried out in Brittany to restore the quality of water. In this context, analysis of the components of the vegetation cover, land cover and landscapes structures that interfere in the hydrological flows requires means and methods that are performing and well adapted to the size of large watersheds. High resolution sensors spot and Landsat TM's potentialities are evaluated in this study to set up methods for mapping land cover, wooded hedges and saturated wetlands at the scale of a large watershed situated in the central Brittany, " le Blavet ". Its size is 2000 km2, and it is characterised with continuous water quality degradation and a high heterogeneity of its landscapes. The methods are first tested and assessed at an experimental scale on the watershed of " Coet-dan " that is 1200 ha large. They point out the effectiveness of landsat tm to extract the linear wooded network and the wetlands on this watershed located in the most intensive part of the entire watershed of the Blavet. The methods are then extrapolated and validated on some sub-watersheds that representative of the mean landscapes units of the watershed of the Blavet. A typology of the hydrological units based on their land cover dominance is suggested from a statistical analysis of land cover data derived from a satellite image. Almost all the wooded hedges and wetlands have been extracted with these methods on the watersheds which are included in open agrarian structures with intensive agricultural practises. The resulting information layers can then been integrated in hydrological models

Full textThis study deals with characterisation of landscapes in Brittany by remote sensing in relation with the fact that the climate varies from one year to another. Four regions of approximately 900 square kilometres (kms) are selected on a Landsat scene and analysed at five different dates : June the 27th of 1976, September the 11th of 1977, April the 17th of 1981, April the 18th of 1984, and august the 17th of 1984. A map of different types of landscape is elaborated by photo interpretation, being a reference to each region; it is used for interpretation of data. The physical description of each region, their agricultural economy and regrouping data are analysed for large areas of encountered landscapes: bocage, mixed landscape and open field. The study begins by a report on the theorical principles of remote sensing (vegetation spectral response) and the evaluation of humidity of soils at recording periods. Follows then the analysis of raw data which reveals areas of distinct landscapes having spectral responses which varies according to seasons. After analysing simple and bidimensionnal histograms on corrected data, the digital separation of different types of landscape occurs to be difficult to produce. Vegetation index translated in colored equidensity gives images comparable to maps obtained by photo-interpretation, and underlines the risky areas as far as dryness in concerned

Full textIn intensive agricultural regions, winter vegetation covering is a key indicator of water transfer processes. Its prediction can help local decision making for restoring water quality. The objective of this work is to develop a reproducible method to predict the land cover distribution for the following winter season for the two hypotheses "Bare soils" and "Covered soils". The selected modelling approach is based on an expert model using the Dempster-Shafer rule. Results are ambivalent according to the studied hypothesis. The prediction scores are good at the watershed scale but present limits for allocating the land class at a field scale, especially for the "Bare soils" class. The Dezert-Smarandache theory is then applied and increases the prediction scores for the "Bare soils" class. The reproductibility of the modelling approach is then evaluated in applying the model on another study site. The "Bare soils" class remains well evaluated with both fusion rules, but the spatial allocation of the land class at a field scale is still not well managed, that indicates the need to integrate new sources of information in the model to better predict the future land allocation

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 textThe urban land use policies, impose a reasonned choice, whose require a descriptive data of the territory to planning. The remote sensing synoptic vision, enable to make e periodic, quantitative and qualitative inventory of land use; the question is to know, if the relation exists between urban object nautre properties and the measured inadiance. This relation was make conspiciously in homogeneous area, like agriculture, hydrology etc. . . The urban area exhibits an extremely heterogeneous surface cover, and it has not e direct relation between physic state of the object ans its urban fonction. Urban e image processing system whose is built on microcomputing an a software entirely developped on the same time of geographic analysis, we process to identify urban land cover for rouen, using the french Spot satellite multiban scene of december 5 1986. It appearead that the use of only one band is not available to analysis when land use, the combination of the three bands is best. The vegetation index give an interesting information. The Spot spatial resolution was nearly urban object height, a textural and structural study was made by using coocurence and isosegment matix. The best way of interpretation remain the visual analysis whose draws it inspiration from the technics of the photo-interpretation
