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 presents our preliminary experimental results on the encountered many problems when producing urban true orthoimages of downtown, where a number of high buildings present. These problems, mainly including building occlusions, street visibility, shadows, incomplete refilling, digital surface model, quality of source images, and the existing orthorectification models, may be common to ...

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.

This study introduces a new geographic framework, phenological classification, for the conterminous United States based on Moderate Resolution Imaging Spectroradiometer (MODIS) Normalized Difference Vegetation Index (NDVI) time-series data and a digital elevation model. The resulting pheno-class map is comprised of 40 phenoclasses, each having unique phenological and topographic characteristics...
