Does the SpaceNet utilities support the Off Nadir Dataset (AOI 6 Atlanta)? #112

Just wanted to know whether the utilities supports the SpaceNet Off Nadir dataset (AOI 6 Atlanta). I tried converting the off nadir annotations into the Darknet format but was unable to do so due to the createDataSpaceNet.py requiring, among other things, matching image and geojson pairs which is not the case for the Off Nadir dataset.

I would highly appreciate some clarification on this matter.

Hi,

We're in the middle of a major revamp of SpaceNetUtilities as well as a variety of other tools in the CosmiQ Works organization (https://github.com/CosmiQ). Once it's completed it'll be much easier to complete tasks like what you're describing; however, at the moment this requires a little hackery. One workaround at the moment would be to duplicate the geojson for each chip location (they're pretty small files) and make one copy named for each collect.

If there are other specific problems with using the off-nadir dataset feel free to post them here and I'll try to help on the side.

Hi @nrweir ,

I do have another doubt regarding the Off Nadir dataset and have opened an issue on it #115. I would highly appreciate any clarification you can provide.
