What are the 4 methods during which the affine transformation might alter a dataset to match it up with one different dataset?
The affine transformation will change the coordinates (and projection) of 1 dataset to match up with the coordinates (and projection of a second). It might try this by rotating (turning), skewing (slanting), scaling (altering the dimensions of the dataset), and translating (altering the situation of the dataset) the information.

Why would georeferencing be with real-world data (and supplies an occasion of this)?
Georeferencing might be utilized to take datasets that might not have spatial reference and apply this spatial reference to them by aligning the information with referenced datasets. If data would not have a spatial reference (akin to a set of plans or a hand-drawn scale diagram), it could actually’t be used alongside facet completely different data layers in several types of geospatial know-how (for instance, it will not match with completely different data in a GIS, or will not appropriately align with a remotely sensed image). An occasion of this could possibly be to take historic maps of an house and georeference them with current maps to see how areas have altered or modified over time.
