Shantanu, It will be a great idea to include GeoTiff capability into Apache Sedona. As for the other libraries mentioned by Jim. In case they plan on pushing their code as part of the Apache Sedona source code, I believe it will not be a good idea for you to push your code. However, in case the developers of these libraries work separately from Apache Sedona and do not refer to it, I do not see why you cannot propose your own solution based upon the Sedona ecosystem. That will benefit the entire Sedona community since they do not need to load extra libraries in order to handle GeoTiff data into Sedona.
Thanks again for your contribution.
