@ian @kgjenkins Yes, I think (70% sure) these are plastic carrier bags full of old roofing.
@geowurster I guess this is what geolocation arrays are for, through. Obviously it’s my first time dealing seriously with this style of georeferencing.
@geowurster The thing is that it’s so oblique at the edges that the terrain correction baked into the GCPs (or whatever the better name is) matters quite a bit. So the common sense thing would be to discard most of them, but I’d rather not do that. Therefore it’s order 1e6 GCPs, which feels like a lot to ask even GDAL, but I haven’t tested!
@geowurster So I sort of talked myself out of GDAL at the beginning of thinking about this, but maybe it’s been the obvious choice all along.
I’m just trying to reproject PACE OCI L1B data, which does the weather satellite thing of having bands for longitude and latitude values, so it’s essentially one GCP per pixel.
I want to map from a small input to a large output with interpolation in the output and I’m going to be able to figure it out but it’s going to feel like doing my taxes the whole time.
This @kissane talk is worth your time if you’re interested in pretty much anything I’m interested in. https://xoxofest.com/2024/videos/erin-kissane/

@sparks I’m not sure either!
@patricio The part of this that I understand, I like.
@hannah [To someone I’ve been talking to about the cool exposed wood ceiling of the wedding venue we’re at:] So what boats are you on?
@caseyg [gesturing dismissively] put something on my calendar
@caseyg okay fine
@patricio Cool stuff, right?!
