> The {{TransverseMercator}} formulas in SIS are different than the formulas that we used
in Geotk (see SIS-249 for more details). Consequently we need to find new formulas for this
map projection derivative.
> The map projection derivatives are needed for enabling the projection, since derivatives
are used for various operations like reprojecting an envelope.
