Catastrophic floods originating from glacial lake outbursts have recently become one of the primary natural hazards in the southeastern Tibetan Plateau. Here we report observations of glacial lake expansions and glacier recessions in the Boshula mountain range, southeast Tibet, derived from multitemporal remote-sensing images and digital elevation models during the period from the 1970s to 2009...

The coastal area is a multi-issue area that promote the production of new data to improve its characterization, including LiDAR surveys (Light Detection and Ranging) for the generation of Digital Terrain Model (DTM) with high spatial resolution. Challenges are located on the integration and the rendering of these data, because of their heterogeneity (images and vectors), but also because curren...

In this paper, we propose a new methodology for extracting river networks from satellite images. It combines morphological generalised geodesic transformations with hydrological overland flow simulations. The method requires the prior generation of a geodesic mask and a marker image by applying a series of transformations to the original image. These images are then combined so as to produce a ...

Owing to the rapid developments in the field of remote sensing, it is being used in a wide range of applications. Especially, based on the purpose, the choice has to be made from the different multi-scale images available. Besides, as remote sensing technology includes the work of aerial survey, DEM (Digital Elevation Model) information can also be obtained. So these technologies can provide la...

Rapid expansion of Torreya forests in the mountainous region in Zhejiang Province in the past three decades has produced many environmental problems such as soil erosion and poor water quality, requiring an update of its spatial distribution in a timely way. However, to date there are no suitable approaches available for mapping Torreya forest distribution, especially the new Torreya plantation...

This paper reviews LiDAR ground filtering algorithms used in the process of creating Digital Elevation Models. We discuss critical issues for the development and application of LiDAR ground filtering algorithms, including filtering procedures for different feature types, and criteria for study site selection, accuracy assessment, and algorithm classification. This review highlights three featur...

In modernen Fahrzeugen verrichten immer mehr elektronische und elektrische Komponenten und Steuergeräte ihren Dienst. Immer kürzer werdende Entwicklungszeiten und eine kurze Prototypenzeit erfordern neue Messverfahren zur Sicherstellung der EMV im Serienfahrzeug. Insbesondere dem störungsfreien Radioempfang kommt dabei eine besondere Rolle zu. Der Vergleich verschiedener Messverfahren mit Hilfe...

Die Ackerschlagkartei der Zukunft darf nicht viel Arbeit machen, muss dem Anwender aber einen hohen Nutzen liefern. RAMIS ist eine solche Schlagkartei. Dazu gehören auch der Empfang von Beratungsempfehlungen oder die Übernahme der einmal eingegebenen Daten für Anträge oder Nachweise.
