An Introduction to Coordinate System Conversions  

In this section, we start to look at techniques for converting between different coordinate systems. At this stage, the tools we have available are Frames ([*]), SkyFrames ([*]), SpecFrames ([*]) and various Mappings ([*]). These are sufficient to allow us to begin examining the problem, but more sophisticated approaches will also emerge later ([*]).
