[GRASS-user] TPIE-based algorithms in GRASS ?

[MORREALE Jean Roc]

Hi,

As Ms. Helena Mitasova was involved int it, I would like to know if 
GRASS is making use (or is planning to) of the research work done by the 
STREAM  project [1] such as TPIE?

Their various publications are showing quite an impressive efficiency on 
using these I/O methods to generate a grid DEM from a huge dataset in 
comparison with surf.rst. I've not been able to find out an open-source 
software based on it as it seems most of the (TERRA)STREAM's devs are 
now behind the proprietary SCALGO software.

Being able to manipulate LIDAR datasets without resorting to tiling and 
multiple regions would be a great thing ! Martin Isenburg is using a 
similar approach in his blast2dem tool, the processing/results are great.

Regards,
