This algorithm analyzes the sound power captured by an acoustic beamformer on a defined spatial grid, estimating the source location as the point that maximizes the output power.
Each 1-ha resolution systematic grid estimated ACD map (see above) represents a stratify-and-multiply upscaling approach whereby the sampled value from the systematic grid (which can be thought of as stratification in this context) is applied to the corresponding unsampled population (the rest of the 1-ha values in the systematic grid cell).
Regional air quality modeling systems, such as the USEPA's Models-3/Community Multi-Scale Air Quality (CMAQ) model in conjunction with meteorological models, link data on meteorology, emissions, and land-use to generate gridded estimates of pollutants, including O3 and PM at various size fractions [ 37].
The population of 5.5 million inhabitants is allocated to the locations of demand points considering the residential population grid to estimate the size of the demand.
In this section, we derive the detection rule for the edge pattern region (pseudoflat region in the LR grid) and estimate the edge direction of the edge pattern.
Moreover, the use of the EEA reference grid to estimate accessibility involves excessive computational load, which makes the present study unfeasible, despite the use of a standard grid overcomes the modifiable areal unit problem (MAUP).
Using a systematic sampling grid to estimate ACD and then upscaling the result at 1-ha resolution using the stratify-and-multiply approach leads to a large percentage of inaccurate estimates across the country (i.e., field plot-estimated ACD failed to be within 10%% of the model ACD) (Fig. 3a, c).
Thus, it seems likely that place and grid cells estimate self-location on the basis of both environmental and self-motion information.
This surface was combined with LandScan global population distribution grid to estimate the spatial distribution of people living with HIV (PLWHIV).
If counting populations of such minute things as living cells, it is helpful to have a counting tool such as a grid to estimate the number of cells within a specific area; otherwise, counting can become cumbersome and time consuming.
