Modeling spatial patterns of shapes [PDF]
We introduce a framework for modeling spatial patterns of shapes formed by multiple objects in an image. Our approach is graph-based where each node denotes an object and attributes of a node consist of that object's shape, position, orientation, and scale.

Spatio-Temporal Sequence Decomposition and Prediction Based on SVD and ARIMA [PDF]
To address the difficulty of estimating the spatial weight matrix in the traditional spatial-temporal sequence modeling process,this paper proposes a spatial-temporal sequence decomposition model,ST-SVD,based on singular value decomposition.The original ...

Underestimates of Grassland Gross Primary Production in MODIS Standard Products
As the biggest carbon flux of terrestrial ecosystems from photosynthesis, gross primary productivity (GPP) is an important indicator in understanding the carbon cycle and biogeochemical process of terrestrial ecosystems.

Spatial pattern switching enables cyclic evolution in spatial epidemics. [PDF]
Infectious diseases often spread as spatial epidemic outbreak waves. A number of model studies have shown that such spatial pattern formation can have important consequences for the evolution of pathogens.

Forests play an important role in maintaining ecosystem services, especially in ecologically fragile areas such as the Loess Plateau (LP) in China. However, there is still great uncertainty in the spatial extent and distribution of forests in such a ...

Small-scale spatial pattern and dynamics of experimental plant communities [PDF]
Plant-plant interference is inherently local and seed dispersal generally limited. Both processes generate spatial and genetic structure within plant populations and communities that need to be better understood in order to predict dynamic community ...

Predicting Climate Change Impacts to the Canadian Boreal Forest
Climate change is expected to alter temperature, precipitation, and seasonality with potentially acute impacts on Canada’s boreal. In this research we predicted future spatial distributions of biodiversity in Canada’s boreal for 2020, 2050, and 2080 ...
