—The ability to assess the influence of site-scale forest structure on avian habitat suitability at an ecoregional scale remains a major methodological constraint to effective biological planning for forest land birds in North America. We evaluated the feasibility of using forest inventory and analysis (FIA) data to define vegetation structure within forest patches, which were delineated from i...

There are various landforms in real word and numerous methods proposed previously for DEM generalization. When use different methods to generalize a DEM, the results vary greatly. Therefore, in order to get a most proper method to implement the generalization, we need taking topographic information into consideration. This paper tested four methods widely used in DEM generalization and compared...

As the core of digital elevation model, interpolation methods have been run through the each link, such as production, quality control, accuracy assessment, analytical applications and etc. The local radial basis function interpolation method based on spatial relationship of natural neighbor was proposed in this paper. The interpolation reference points were chosen by the Delaunay Triangulation...

In this study we evaluate whether the methodology of Boosted Regression Trees (BRT) suits for accurately predicting maximum wind speeds. As predictors a broad set of parameters derived from a Digital Elevation Model (DEM) acquired within the Shuttle Radar Topography Mission (SRTM) is used. The derived parameters describe the surface by means of quantities (e.g. slope, aspect) and quality (landf...

In the largest known population of sinuous ridges on Mars, Aeolis Serpens stands out as the longest ( 500 km) feature in Aeolis Dorsa. The formation of this landform, whether from fluvial or glacio-fluvial processes, has been debated in the literature. Here we examine higher-resolution data and use a terrestrial analog (the Mirackina paleoriver, South Australia) to show that both the morphology...

This paper describes the tools developed to link the SIBERIA model with a GIS. SIBERIA simulates the evolution of landforms within a catchment using digital elevation data. Integration of SIBERIA with a GIS provides easier access to the model for non-specialist users, and also extends model functionality. The complexity of the model means that integrating the two technologies using an ‘embedded...

tion of a tongue-shaped landform located in the Hellas Montes area and summarize morphologically derived evidence that this landform (a) originates at a formerly unknown volcanic edifice located in the north, (b) is probably older than previously assumed, (c) has been resurfaced by subsequent mass-wasting processes taking place ontop of the flow, and (c) shows a substantial degradation morpholo...
