Hi Artem
You're right, just subscribed.
Again you are right, I want to turn screen coordinates into real world ones
and from there on I will be able to turn them into MGRS rather than just
UTM.
I've been trying this with the simple viewer:
CoordTransform
t(map_->getWidth(),map_->getHeight(),map_->getCurrentExtent());
double x = (double) e->x();
double y = (double) e->y();
coord2d coord;
coord = coord2d(x, y);
t.backward(coord);
std::cout << coord << std::endl;
Stockholm, Sweden is here coord2(1614085.074371404,6574896.886350079).
Now I've really been trying to figure out what this represents but I
couldn't find it anywhere.
Best regards,
Carl
