We actually took open source topographical maps of the country and then loaded those — along with more precise 3D surveys of the delivery sites that we serve — we loaded those both into the navigation system of the airplanes so that when you have a package the vehicle is scanning the barcode of that package and then instantly has its mission.
"By using administrative data," he says, "they're able to get much more precise measurements than surveys generally provide, and a much larger sample of individuals".
Uzawa (2003, pp.1-21) gives a precise survey of more specialized articles concerning global warming as it relates to economic theory.
Despite acknowledged shortcomings, household consumption and expenditure surveys (HCES) are increasingly being used to proxy food consumption because they are relatively more available and affordable than surveys using more precise dietary assessment methods.
Finding sparse solutions has brought practical benefits such as the need of fewer antennas for remote sensing, fewer measurements needed in geophysical surveys, and more precise identification of genes.
Using a design consisting of different surveys results in more precise parameter estimates of the underlying discrete choice model than a design consisting of a single survey [ 19, 20].
This GIS-based study used aerial oblique photography and satellite optical imagery, complemented with a land survey for a more precise topographic reconstruction.
8 Conducting a larger, more representative survey, would provide more precise information about patient recording, but it is likely that such a snapshot would be transient, and would not add much more to an understanding of motivations and utility.
In many cases, the broad survey of eukaryotes in this study enabled more precise identification of orthologous meiotic genes than previous smaller datasets permitted.
However, the SD of these estimates declined with increases in the survey proportion resulting in more precise estimates.
