Comparing sample bias correction methods for species distribution modeling using virtual species
Ecosphere, 2021 A key assumption in species distribution modeling (SDM) with presence‐background (PB) methods is that sampling of occurrence localities is unbiased and that any sampling bias is proportional to the background distribution of environmental covariates ...

The spatial structure of networks [PDF]
, 2004 We study networks that connect points in geographic space, such as transportation networks and the Internet. We find that there are strong signatures in these networks of topography and use patterns, giving the networks shapes that are quite distinct ...

Visualizing the dynamics of London's bicycle hire scheme [PDF]
, 2011 Visualizing flows between origins and destinations can be straightforward when dealing with small numbers of journeys or simple geographies. Representing flows as lines embedded in geographic space has commonly been used to map transport flows, especially ...

Space-contained conflict revision, for geographic information [PDF]
, 2007 Using qualitative reasoning with geographic information, contrarily, for instance, with robotics, looks not only fastidious (i.e.: encoding knowledge Propositional Logics PL), but appears to be computational complex, and not tractable at all, most of the

Heat and Drought Stress Advanced Global Wheat Harvest Timing from 1981–2014
Remote Sensing, 2019 Studying wheat phenology can greatly enhance our understanding of how wheat growth responds to climate change, and guide us to reasonably confront its influence. However, comprehensive global-scale wheat phenology–climate analysis is still lacking.

Spatio-textual indexing for geographical search on the web [PDF]
, 2005 Many web documents refer to specific geographic localities and many people include geographic context in queries to web search engines. Standard web search engines treat the geographical terms in the same way as other terms. This can result in failure
