I have two layers in a QGIS project: "Layer 1" and "Layer 2".
In their "Layer Properties" under "Coordinate Reference System" I see this:
I'm trying to understand the differences between the CRS nomenclature.
Layer 1 is obviously projected, since it says UTM zone 20, but I'm left wondering what the datum is that it's based on?
Layer 2 tells me its datum = WGS 84, but I'm left wondering what its projection is?
It appears to me the various CRSs shown in both screen shots use various combinations of datums and projections terminology. This appears needlessly confusing. Only the bottom one appears to clarify both its datum (NAD83) as well as its projection (UTM).
New Question /Task:
Top marks to the one who can accurately describe the meaning of every component (word, number, punctuation mark, etc) in all 4 CRSs appearing in Layer 1, particularly so that the datum and coordinate system are clearly defined.
