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 (
), TimeFrames (
) and
various Mappings (
). These are sufficient to allow us to
begin examining the problem, but more sophisticated approaches will also emerge
later (
).
