Laura,

Take a look at the subject headings
"Triangulation" and "Geodesy". The control points
you mention are part of a "triangulation" system
for fixing specific locations on the surface of
the earth, and Geodesy is the science/discipline
encompassing this. Triangulation can be
subdivided geographically, as can Geodesy.
"Surveying" is also an acceptable heading for
this kind of map, though in my mind broader than
perhaps what the map shows. You might note when
looking at the authority record for "Geodesy" the
Used For cross reference of "Earth $x
Measurement" which might help you hone in on what
the map's purpose is about. Also, there's a scope
note about using the topical heading of "Surveys"
subdivided geographically if you think that is useful.
