    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.

    yeah, and then you need to get refreshed orbital elements for those satellites. not good if you are in an airtight environment. celestial ephemerides don't change nearly as much.

    it's useless thence I love it. I lied, in fact I just used it to create a couple Slack emojis.

    it's also not the proper scale type for sequential data (red/green is diverging, but there is no central value defined in the linked map).

    For those less obsessed with SAR images Touché! Also good point regarding multibounces and multipath. I would expect eg. landing gear returns to be standing out in those cases (coc…

    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…

    A little nitpick about: The number of looks correlates with a higher resolution. Yes and no. When you task an image, you usually (as is the case with Umbra) specify your desired gr…

    yes, received power is inversely proportional to the distance squared. it's hard to overstate how ridiculously small the amounts of power are at play with spaceborne SAR systems.

    most complex and/or commercial aircraft do share the workload between a pilot-flying, and a pilot-non-flying—in addition to the captain & FO hierarchy you are probably aware of.

    the conning officer often has tons of other stuff to deal with that require them not to be distracted by having to change course themselves.

    not sure why you are getting downvoted, that was a funny reference to Ariane 501/V88.
