Arbia's law of geography

[8] In spatial analysis with geographic information systems, both raster and vector data are used.

[1] Arbia's law is important to remember when working with raster data, particularly remote sensing, where the electromagnetic spectrum is sampled at a pixel level.

[15][16] The Modifiable Areal Unit Problem, or MAUP, arises from the countless possible ways to divide up the same area of land.

How land is aggregated can affect the results or analysis, an effect that has been exploited by politicians through the process of gerrymandering.

Arbia's law applies not just to how data are aggregated spatially but to the size of the aerial units.

[17] In general, some dispute the entire concept of scientific laws in geography and the social sciences.
