Hi Steve,
Bearing in mind that the software is used in non-land based applications to
build TINs representing all sorts of other data, the only generic term can
be TIN. The difficulty with "TIN" is that the terminology is far less
likely to be a part of a user's normal knowledge set than "Surface" or
"DTM".
A couple of examples of other uses are:
Electro-potential at the surface of a re-inforced concrete wall.
Surfaces for jewellery design
Gross rainfall from a rainfall event
Arising from the early software written for Civil/Survey in Australia the
most common terminology (particularly with Surveyors) here is "Contour" as
in:
"Can it create contours?"
"Does it contour?"
"Contourable data"
