[Use case] Transform projection of `sftraj` #5

Closed jmsigner closed 4 years ago

jmsigner commented 5 years ago

Use case: Transform the coordinate reference system (CRS) of a sftraj.

Requirements: A sftraj.

Input: A sftraj with a valid CRS and a EPSG code.

Output: A sftraj with the CRS transformed to the new ESPG code.

Additional information: I would expect this to be similar to sf::st_transform.

Yes, indeed! Ideally, it would be sf::st_transform. sftjraj will rely heavily on sf objects (hence the name), so we will try to make it transparent for the user. In this use case, sftraj objects would need to nicely handle CRS and reprojections.

I'm re-opening some of these use-cases so theyre easier to find as people submit new ones.
