Timing of erosion and satellite data: A multi-resolution approach to soil erosion risk mapping☆
TLDR
The presented approach that uses coarse-resolution temporal data for determining erosion periods and medium-resolution data for effective erosion risk mapping is fast and straightforward and shows good potential for successful application in other areas with high spatial and temporal variability of vegetation cover.About:

Soil erosion and sediment yield and their relationships with vegetation cover in upper stream of the Yellow River
TL;DR: The relationships between soil erosion and sediment yield with vegetation NDVI indicated that the vegetation status has a significant impact on sediment formation and transport, and can be used to develop soil erosion conservation programs for the study area.

Overview of the radiometric and biophysical performance of the MODIS vegetation indices
TL;DR: In this paper, the authors evaluated the performance and validity of the MODIS vegetation indices (VI), the normalized difference vegetation index (NDVI) and enhanced vegetation index(EVI), produced at 1-km and 500-m resolutions and 16-day compositing periods.
Journal ArticleDOI
On the relation between NDVI, fractional vegetation cover, and leaf area index
TL;DR: In this paper, a simple radiative transfer model with vegetation, soil, and atmospheric components is used to illustrate how the normalized difference vegetation index (NDVI), leaf area index (LAI), and fractional vegetation cover are dependent.

Quantitative analysis of land surface topography
TL;DR: In this article, a system which determines slope, aspect, and curvature in both the downslope and across-slope directions is developed for an altitude matrix, and the upslope drainage area and maximum drainage distance are determined for every point within the altitude matrix.

TL;DR: The Tropical Rainfall Measuring Mission (TRMM) was launched on 27 November 1997, and data from all the instruments first became available approximately 30 days after the launch as mentioned in this paper, and much progress has been made in the calibration of the sensors, the improvement of the rainfall algorithms, and applications of these results to areas such as data assimilation and model initialization.

A new procedure for gridding elevation and stream line data with automatic removal of spurious pits
TL;DR: In this article, a morphological approach to the interpolation of regular grid digital elevation models (DEMs) from surface specific elevation data points and selected stream lines is described, which has given rise to a computationally efficient interpolation procedure which couples the minimization of a terrain specific roughness penalty with an automatic drainage enforcement algorithm.
