A multi-scale approach for retrieving proportional cover of life forms [PDF]

, 2008
This study presents a multi-scale procedure to derive continuous proportional cover of woody vegetation in savanna ecosystems. QuickBird data was classified to define a continuous training and validation data set of woody cover proportions.

Multi-scale associations between vegetation cover and woodland bird communities across a large agricultural region. [PDF]

PLoS ONE, 2014
Improving biodiversity conservation in fragmented agricultural landscapes has become an important global issue. Vegetation at the patch and landscape-scale is important for species occupancy and diversity, yet few previous studies have explored multi ...

Assessing Vegetation–Hydrothermal Trend Regimes Across Elevation Gradients in Semiarid Mountains via Gaussian Mixture Models in Saudi Arabia

Remote Sensing
Vegetation–hydrothermal trend patterns in semiarid mountains are inherently multidimensional across altitudinal gradients, requiring probabilistic frameworks to characterize overlapping vegetation–hydrothermal trend patterns.

Combined Effects of Impervious Surface and Vegetation Cover on Air Temperature Variations in a Rapidly Expanding Desert City [PDF]

The goal of this study is to improve our understanding of the interac- tive function of impervious and vegetation covers at different levels of the local and intra-urban spatial scales in relation to air temperatures in an urban environment.

Combining optical satellite data and airborne laser scanner data for vegetation classification [PDF]

, 2011
The aim of this study was to investigate to which degree the accuracy of vegetation classification could be improved by combining optical satellite data and airborne laser scanner (ALS) data, compared with using satellite data only.
