[Gdal-dev] Reading TIN data?

[Ben Discoe]

I've come across some TIN (triangular irregular network) data which has been
written by an ESRI product, so it is in the form of a directory with .adf
files.  Is it possible at all to read from this dataset with GDAL or OGR?  A
TIN isn't quite a raster nor a vector, so i can understand if neither
library is set up to handle it.  On the other hand, GDAL does read raster
data from .adf, so perhaps some of the work is already in place.

The contents of the dataset folder are:
 tdenv.adf
 tedg.adf
 thul.adf
 tmsk.adf
 tmsx.adf
 tnod.adf
 tnxy.adf
 tnz.adf

Note there is no "hdr.adf", which is what GDAL looks for, for a raster.

Thanks,
Ben
