That's true. I have a bias of having part of my formal education quite focused on geospatial topics. Seeing non-geospatial folks reinventing wheels taught in GIS 101 both makes me …

it depends on what flavour of English you speak. British English for instance tends to use plural for collective nouns.

This sounds like marshrutki. These are very common in post-Soviet countries to fill the demand left unmet by public transportation service.

the TCAS data would have been displayed. but not on instruments or in any place that you typically pay attention to the most during final visual approach (ie., mostly outside).

TCAS RAs are inhibited at low altitude.

Yes, radar shadow is how you would find it. But your sensor must be performing well enough for it to be able to distinguish a shadow from the surface backscatter (ie. radar signatu…
