Hello, I have another question, this time about transforms to WGS 84.
It's quite common in geoscience to pick not the just the CRS that a dataset uses, but also to pick at the same time the matching transform to WGS 84. For example, when a user picks the 32056 - NAD 27 / Wyoming East Central CRS, the EPSG database has several possible transformations to WGS 84. One of them is 1173 - NAD27 to WGS 84 (4) USA - CONUS - onshore. I couldn't find a way to pass this transform to the CRS.findOperation method. I do understand that: - this transform is often not needed, as better methods than using WGS 84 as a hub can be used (NADCON, NTV2, HARN, etc) in many areas - passing the bounding box technically allows Apache SIS to pick the best transform for that bounding box However, in many geoscience applications, the user wants to "pick" this transform to WGS 84 themselves, and use WGS 84 as transformation hub if no other method is available. Does Apache SIS support transforms to WGS 84? Is there a way I can specify a transform to WGS 84 when I find an operation, especially outside of an NADCON/NTV2/HARN area? -Thierry
