[GRASS-user] Compiling NVIZ / OpenGL with nVidia drivers

. NVIZ works fine when I download the binary in a pre-compiled version of grass. So far, I can only get grass to compile with --without-opengl. Thanks John -- Dr John Stevenson Postdoctoral Research Associate School of Earth, Atmospheric and Environmental Sciences Williamson Building

Re: [GRASS-user] Appropriate use of v.surf.rst (lidar data)

ong time with LiDAR data. The examples on p53-54 of the gstat manual describe how you can limit the analysis to a local neighborhood or set a maximum number of points to include in each calculation and thus dramatically speed up the interpolation. (http://www.gstat.org/gstat.pdf) Later

where they need to smooth with r.neighbors (method=average/median, size > 5)? I would be interested to know, and to see if this algorithm would be useful. Cheers John -- Dr John Stevenson Postdoctoral Research Associate School of Earth, Atmospheric and Environmental Sciences Williamson

It is also useful to know that if you work somewhere with access to Springer academic journals (e.g. a university), you can download the GRASS book under their subscription: http://www.springerlink.com/content/j21632/ Cheers John -- Dr John Stevenson Postdoctoral Research Associate School
