I just copied his implementation, adapting it to the proj4js interface. Now I realize that the variable world extent that this projection uses is very impractical in Openlayers, so I am wondering * What is the reason for the variable world extent? It varies with the height, being larger for larger heights * Should this projection in proj4js work the same way as PROJ.7? Any advice would be greatly appreciated -- Momtchil Momtchev -------------- next part -------------- An HTML attachment was scrubbed... URL:
