These layers are co-registered to the same spatial extent at a common 30m spatial resolution.
To account for spatial extent mismatches between ground plot size and predictor variables, we resampled all predictor variable spatial data to a 20 m × 50 m pixel size using a nearest neighbor method which maintained the actual pixel values.
Mismatches between the spatial extent of the HYDE calculated rates and GRUMPv1 population data were resolved via infilling rate cells based on a focal mean of values.
GIS-based exposure models, now common in environmental epidemiology, should be validated to the spatial extent of the cohort examined, and spatial patterns in stressors and pollution, at multiple levels, should be carefully considered to avoid spatial misclassification and confounding.
Statistical significance and strength of the associations between the environmental factors and spatial extent of the potential locust habitats was tested by Student t test.
Edge effect estimated by a common, widespread, easily identified perennial herb could permit an estimate of the spatial extent of edge habitat for other understory plant species, an important consideration in forest ecosystem management.
Chandler's early city population estimates used the spatial extent of the city to estimate the population using a common population density of the region and time period.
While differential spatial coverage between sessions precludes direct comparisons and spatial surfaces should be interpreted with caution given the visual display of some areas outside of the spatial extent of sampling, general spatial patterns are qualitatively consistent between sessions, with higher concentrations generally detected northwest of the airport and near major roadways.
This illustrates how the broad spatial extent of 'rangeland' has created on-going confusion and gaps between scientific work and management approaches.
Finally we look at the spatial extent of the discovered types both within a layer and between layers.
The non-ratiometric thrombin ACPPs also showed a correlation between thrombin activity and the severity and spatial extent of damage in the ischemic core of stroke.
