[GRASS-dev] new baseline NC data set

[Helena Mitasova]

I have posted a grass7 location for what should eventually become a new baseline NC data set
http://skagit.meas.ncsu.edu/~helena/grasswork/grassbookdat/loc_ncarolina_spm_base0.2.zip
it has easy to understand names for basic raster and vector map layers and the roadsmajor
and streets data are updated based on 2011 data provided by Wake county. Please let me know
if these street data still have problems, there are other versions of this data set available, e.g. for LRS
applications etc.

The more complex data available in the current nc_spm_08, such as different types of DEMs and elevation point data,
landsat, and any other more specialized or complex data will be 
provided as separate mapsets (distributed separately or in a NC-complete location).

This is very much work in progress with a long TODO list (e.g. incorporation of metadata)
 aimed to be ready for grass7 release, but feedback is always appreciated.

I'm trying to make some additional suggested enhancements to the documentation to make this complex but useful set of modules more accessible. I'll copy you along with Moritz and Markus.
