Spatial distribution

One example of such a display could be observations made to describe the geographic patterns of features, both physical and human across the earth.

The issue can be demonstrated with several simple examples: The spatial distribution of the population and development are closely related to each other, especially in the context of sustainability.

[2] In a pair of studies from Brown University by urban economist J. Vernon Henderson, with co-authors Adam Storeygard and David Weil, the spatial distribution of the economic activity in the world was examined by mapping the artificial lights at night from space over 250,000 grid cells, the average area of each of which is 560 square kilometers.

[3][4] The seismic intensityies of an earthquake are distributed across space with an elementary regularity, so that in towns located close to the epicenter of the earthquake, high seismic intensities are observed and vice versa; Low intensities were observed in settlements far from the epicenter.

The distance of each settlement from the epicenter is marked with XY coordinates, a variable that affects the seismic intensity observed there.

The curve above expresses the slope of the seismic intensity as a function of the distance from the epicenter, R 2 =0.26 . When in a certain methodology the influence of the geological structure variable of each observation was neutralized, the R 2 increases to 0.41, which means that the distance together with the geological structure already affect 41% of the variation in the spatial distribution of the intensities, and so on, one can continue and try to understand the effect of the other variables.
