This processor requires the EPSG Setup. That is why there is an E in the symbol. The user documentation is still missing on the website, so the URL cannot be referenced here. So this is a future to do. -- This is an automated message from the Apache Git Service. To respond to the message, please log on to GitHub and use the URL above to go to the specific comment.
