This type of projection is often used e.g. in exhibitions that leverage big curved screens. Effectively, the frame is mapped onto a cylinder, with the x axis becoming the longitude and y axis becoming the height. Users can configure the min/max longitude, the min/max height and the radius of the cylinder.
