Hi.
I work on OpenTripPlanner, a multimodal trip planner. We recently had
to integrate the National Elevation Dataset (NAVD88) and OpenStreetMap's
elevation data (WGS84). I hacked together some conversion code inside
OTP, but I think I might not be the only one with this problem.
I wonder if it would be useful to add this code to GeoTools. I would be
happy to do some work on this, but I have a couple of questions first:
(1) The conversion requires ~70 MB of data. Is that reasonable?
(a) What's the right place to put the new code and the large amount
of data? A separate module?
(2) I'm not sure I understand exactly how to implement this inside
Geotools; the conversion code is not complicated, but the various
VerticalDatum APIs are. If someone could point me to an example or some
docs other than the JavaDoc, that would be great.
If it turns out that this isn't right for Geotools, that's OK too; we'll
just maintain it inside OTP.
