    I should definitely check out the varied cotton or linen weaves, then! I mainly wear a very light button down polyester for field work because of the benefits I mentioned and durability. I do a good bit of walking through thick brush and it’s nice that it doesn’t “pull” too much.

    As someone who sweats a lot and works outside in brutal heat, I find the complete opposite is true regarding cotton vs polyester. Polyester wicks away the sweat and evaporates quickly, while cotton just soaks and turns hot, wet, and heavy.

    I wish it were the opposite so that I could use less plastic overall, but I haven’t found that to be the case.

    Either way, a loose fit and complete skin coverage from the sun is essential.








  • Short answer: yes

    Pretty much all of the imagery options available on ID are orthoimagery, since that just means it’s been corrected to remove distortions from camera angle, lens, and topography.

    Unfortunately, that doesn’t always make them perfectly accurate. The only good way to check if a particular dataset is accurate is to record GPS along a feature identifiable in the imagery and check out the offset.

    Usually the best one to use is a more local survey that covers just the city (usually only done for larger cities). Also ones where the area you’re tracing has a more “overhead” camera angle (hard to trace when the top of tall buildings are very offset from their base).

    I think the RapID editor automatically provides a few additional local imagery sets, depending on where you are working.
