I have a WWII vintage map, prepared for the US Army based in Australia that was used to determine bearings for directional HF radio antennae from Brisbane Australia (where the map is centred) to any other point in the world.

 

It is hand drawn, and i’d like to digitise it into Mapinfo in part to help preserve it, and to be able to plot it at various scales etc.

 

Does anyone know how to cater for projections like this?  I guess it is some form of polar projection, but I have no experience with anything like this.

 

Thanks in advance
