This study focuses on the glacial landform record associated with recent surge events of Tunabreen a calving tidewater glacier in Tempelfjorden, Spitsbergen. Submarine geomorphology and recent terminal fluctuations of Tunabreen’s glacier front were studied using high-resolution multibeambathymetric data and a range of published and remotesensing sources, including topographic maps, satellite im...

Previous studies suggest that rodent burrows, a proxy for rodent population are important for predicting plague risk areas. However, studies that link landform, surface attributes and rodent burrows in the Western Usambara Mountains in Tanzania are scanty. Therefore, this study was conducted in plague endemic area of the Western Usambara Mountains in northern, Tanzania, to explore the relations...

This paper presents LANDFORM, a customized GIS application for semi-automated landform classification based on the definitions of SPEIGHT (1990). A set of commands for GeoMedia was developed for an easy step-by-step generation of topographic attributes for the classification of landform elements. Using the new commands topographic attributes like curvature or elevation percentile were derived f...

In the process of analyzing aerial photographs to obtain information on the engineering characteristics of soils, the first and perhaps the most important step is to identify the landform. The landform may consist of hills, valleys, plains, terraces, beaches, dunes, and other topo­ graphic features largely created by the forces of erosion. The im­ portance of the landform lies in its relation t...

-For the need of digital basin 3D simulation, the paper proposes a visualization optimization method for large-scale landform and flow pattern. Based on call of landform data partitioning organization and dynamic processing of visual regional data, for the present situation of commonly using ADO(ActiveX Data Objects) developing interface to realize the operation for database, OCI (Oracle Call I...

Management of desert grasslands requires rapid, low technology, coarse assessment methods that provide a triage-like prioritization for the manager. Such approaches necessitate the ability to quickly and effectively identify coarse-scale plant communities that provide guidance for this prioritization. Complex, computer intensive digital image classification of Landsat TM data, while marginally ...

In this work we presented a methodology based on non linear regression for Landform Attributes representation. The equations to estimates the parameters of a two dimensional polynomial are shown and, for testing the methodology, it was used the data of Landform Attributes from the state of Minas Gerais (Brazil) obtained by the Digital Model of Elevation (DME) from GTOPO30 [5] project, in the fo...

the aim of the study is the classification of landform based on elevation, slope, relief and curvature inputs (old method) and topographic position index (tpi) (new method) in the south of bojnoord. the input data for the two methods is a digital elevation model (dem). the results of topographic position index (tpi) model showed that most area of landform were covered by class 5 (plains small) ...
