Seismic imaging in thrust-belt environments like the foothills of the Himalayas benefits significantly from interpretive input to velocities used for time and depth migration. With low fold in the near surface, low signal-to- noise ratios on the image gathers, ...

Landslides are a recurring problem on hillslopes throughout the Puget Lowland, Washington, but can be difficult to identify in the densely forested terrain. However, digital terrain models of the bare-earth surface derived from LIght Detection And Ranging ...

This paper describes the application of an automated method of analysis of 3D images that provides users with the capacity to map exposed structures automatically. The method is based on the use of vector classification methods used in some neural network ...

The accuracy of forest stand type maps derived from a Landsat Thematic Mapper (Landsat TM) image of a heterogeneous forest covering rugged terrain is generally low. Therefore, the first objective of this study was to assess whether topographic correction of ...

<p>Accurate measurement of soil deformation is fundamental to the success of geotechnical modelling. Current practice is to track the movement of a grid of target markers embedded in an exposed plane of soil through a sequence of video images. A new system ...
