A talk at the Harvard-Smithsonian Center for Astrophysics, May 6, 2015

Over the past 45 years, I've developed an interest in maps
into a variety of software which implements a variety
of mapping functions to translate between images, catalogs,
and precise coordinates in space. After several less
portable programs, I wrote WCSTools, a user-friendly suite
of software to do all of those things, with a variety
of other tools added to manipulate files. To cover
the third dimension, I added the RVSAO package to IRAF to use
various methods to compute radial velocities and redshifts
from spectra of astronomical objects, be they
asteroids, stars, or galaxies. I'll discuss the evolution
of these tools and the astronomical data environment.
