floods from both inland and sea removed the houses and debris.
only way to mark them is based on location in the “before” .
As much as possible, mark the footprint of the house on the NOW / After event tile. Do your best. When I compare now to before, I can delete a misplaced tag and re-tag the spot.
Oh, and on maps like that, I just tag “rows”. It covers most of the houses.
do you know if the system takes into consideration on which map the tag was done? the “before” or “after” ? will the coordinates be taken differently to make them match?
Hover your mouse over a focal point in the before image and switch to the after image, that’s always a good indicator as to how far out of alignment the maps may be and in what direction.
Now when deciding on where a building used to be, you just do a similar thing. Hover your mouse over a building in the before image, switch to the after and drop a tag roughly where it should be (correcting alignment if need be).
Thanks @EmeraldEyes , yes I do that too. but sometimes it is easier just to mark the buildings where they used to be in the before. where you actually see’em
Yes, I’ll do that if I can’t pinpoint them accurately enough but then (being a little OCD) I’ll shift them over in the after image, possibly to the most dense part of the debris pile. But I doubt it matters to the system, which maps the tag is dropped on in that respect I’m sure @Mel_Nod will let us know if it does
I believe Tn Staff has to move the tags placed on Old/Before imagery and put it on the New/Current imagery – for uniformity of data output.
(Or because moving tags using a small staff is time consuming, they could just dump the errant tags. I think they try to move them / merge them, though.)
