Digital Elevation Models: Terminology and Definitions

Remote Sensing, 2021
Digital elevation models (DEMs) provide fundamental depictions of the three-dimensional shape of the Earth’s surface and are useful to a wide range of disciplines.

Egg parasitoids from the subfamily Scelioninae (Hymenoptera: Platygastridae) in irrigated rice ecosystems across varied elevational ranges in southern India.

Journal of Threatened Taxa, 2016
Platygastridae (Hymenoptera) is the most abundant family of parasitic Hymenoptera in rice ecosystems in southern India.  Members belonging to the subfamily Scelioninae were assessed in rice ecosystems along three elevation ranges, a highland (737m ...

Leaf traits divergence and correlations of woody plants among the three plant functional types on the eastern Qinghai-Tibetan Plateau, China

Frontiers in Plant Science, 2023
Leaf traits are important indicators of plant life history and may vary according to plant functional type (PFT) and environmental conditions. In this study, we sampled woody plants from three PFTs (e.g., needle-leaved evergreens, NE; broad-leaved ...

Resolution of a paradox: Hummingbird flight at high elevation does not come without a cost [PDF]

, 2004
Flight at high elevation is energetically demanding because of parallel reductions in air density and oxygen availability. The hovering flight of hummingbirds is one of the most energetically expensive forms of animal locomotion, but hummingbirds are ...

Spectral filtering as a method of visualising and removing striped artefacts in digital elevation data [PDF]

, 2008
Spectral filtering was compared with traditional mean spatial filters to assess their ability to identify and remove striped artefacts in digital elevation data. The techniques were applied to two datasets: a 100 m contour derived digital elevation model

20-Degree Elevation to Reduce Swelling and Pain After Lower Extremity Open Reduction and Internal Fixation Surgery

Jurnal Keperawatan Indonesia, 2021
Surgery for open reduction and internal fixation (ORIF) causes tissue swelling and pain in the surgical area. Swelling and pain can be reduced by performing distal elevation in the area of surgical ORIF.

Influence of bed elevation discordance on flow patterns and head losses in an open-channel confluence [PDF]

, 2019
Confluences play a major role in the dynamics of networks of natural and man-made open channels, and field measurements on river confluences reveal that discordance in bed elevation is common.

New elevation data triple estimates of global vulnerability to sea-level rise and coastal flooding

Nature Communications, 2019
Most estimates of global mean sea-level rise this century fall below 2 m. This quantity is comparable to the positive vertical bias of the principle digital elevation model (DEM) used to assess global and national population exposures to extreme coastal ...

ICESat/GLAS Data as a Measurement Tool for Peatland Topography and Peat Swamp Forest Biomass in Kalimantan, Indonesia [PDF]

, 2011
Indonesian peatlands are one of the largest near-surface pools of terrestrial organic carbon. Persistent logging, drainage and recurrent fires lead to huge emission of carbon each year.
