Hi, I found an interesting post regarding proj4j. That's why I prefer the SIS approach with external database. What do you think about the mentioned "copyright infringement" opinion?
PROJ claims to be under MIT license, but in my understanding this is copyright infringement. PROJ license should be MIT + EPSG terms of use. The whole post is: > Proj4J (and its parent PROJ project) includes EPSG > data, so the use of Proj4J dependency implies accepting EPSG terms of > use [1].
