[OSGeo-Discuss] C++ library for "gridding"

[Venkatesh Raghavan]

Hi All,

Our colleagues in China have informed that they are
working on modifying GRASS commands for data
processing and analysis to C-API functions.

Perhaps, Helana and others would work together
or support Prof. Chen in speeding up development
of the GRASS C-API.

Regards

Venka
