we have found images, which have displaced color images (it looks like that channels have been acquired at slightly different times). The phenomenon is not visible for the most of the image, but in our task - finding commercial aircraft on satellite images, the artefacts are highly visible, as in the image below:
The image in question is 20190921_025440_53_105c_3B_AnalyticMS_SR.tif
The crop-out of the image is from the right side of the image, almost at the edge. I can get you speed of the aircraft if you need it to estimate the delay between the channels... but don't have it at hand right now.
We also found other images with same artefacts, but for the most part, the images do not exhibit this (airplanes are in white color, as they should be). My question is, is this can be fixed, is it some kind of postprocessing artefact or is simply the error in acquisition that cannot be fixed post acquisition?
Another question: having the image ID, how can one find this image via planet.com's web page? We are preparing a metadata-dataset that would not contain images, but will refer to image ID, allowing the researchers to download exactly the same data after they get subscription to Planet.com.
Another question, who do I contact regarding the Educational and Research Program? Where do we send published papers, etc? Or ask further questions regarding the dataset?
