Scale has many meanings, but in GIS two are of greatest significance: resolution and extent.
Ideally models of physical process would be defined and tested on scale-free data. In …

Rugged terrain, including mountains, hills, and some high lands are typical land surfaces
around the world. As a physical parameter for characterizing the anisotropic reflectance of …

Multibeam surveys can provide detailed bathymetry data for the continental slope from
which quantitative descriptors of the seabed terrain (eg, slope) may be obtained. We …

This work studies multiscale analyses and characterizations of surface topographies from
the engineering and scientific literature with an emphasis on production engineering …

In this paper a spatially distributed model for the calculation of sediment delivery to river
channels is presented (SEDEM: SEdiment DElivery Model). The model consists of two …

Regional studies of fluvial landforms and long-term (Quaternary) landscape development in
remote mountain landscapes routinely use satellite-derived DEM data sets. The SRTM and …

A desertification monitoring system is developed that uses four indicators derived using
continental-scale remotely sensed data: vegetation cover, rain use efficiency (RUE), surface …

Rainfall‐simulation experiments have been carried out on a series of plots ranging in size
from 1 m2 to c 500 m2 in order to observe process and flux‐rate changes resulting from the …

Primary topographic attributes play a critical role in determining watershed hydrologic
characteristics for water resources modeling with raster-based digital elevation models …

尺度是与空间现象有关的术语, 在地学研究中更是一个重要的概念. 忽视遥感观测的尺度效应,
使得对地观测难以获得精确的地表参数. 这一问题已经引起国际遥感界的重视 …
