Just to add to the discussion:
For introductory material a simpler, basic data set may be more useful than the
rather complex nc_spm_08,
for example, here is one in GRASS format (47MB)
http://grass.osgeo.org/sampledata/north_carolina/nc_basic_spm.tar.gz
I have prepared this data set because I thought that it would be useful
to have a set of simple data sets for different regions with standardized
names of data layers
so that we can use the same tutorial with data sets from different regions.
So Simon, if you are going to create a data set for Australia to go with your
tutorials,
it would be great if you could use the same names as in our basic data set (or
if you have a suggestion
for a different name, please let me know - at this stage it will be easy to
change it on
our side). Then we can use your tutorial with our nc data set and students/users
in Australia can use our tutorials with your data set. We can have this for
many countries
and many different software packages we just need to agree on the names for
data layers.
There are certain tasks that are region specific, such as the coordinate
systems,
but many tasks, from display to analysis, would be the same.
In the nc_basic I have used the following names (I will be happy to modify
whatever is needed):
raster data:
basins elevation elevation_shade geology lakes landuse soils
vector data
boundary_region/ elev_points/ geonames/ railroads/
streams/
boundary_state/ firestations/ hospitals/ roadsmajor/
streets/
census/ geology/ points_of_interest/ schools/
zipcodes/
We can provide the data set in other formats (similarly as we did for nc_spm_08)
and add additional type of data such as orthos or landsat.
There is a brief CLI tutorial available for GRASS with this data set
but I would like to prepare some screencaptures on "Getting started GRASS with
wxGUI"
with this data during the upcoming GRASS community sprint in Prague
(where I can hopefully learn everything that I might have missed about the ne
GUI
and we can capture its proper use).
The larger data set nc_spm_08 is much more complex and goes with the GRASS book
and
I am also using it for my course. I plan to release some additional,
applications
oriented mapsets for this data set, but this all goes beyond the intro
tutorials.
So I very much agree with Simon that we need diversity in the data sets
both in terms of scale and geographic location, but it would be useful
to use standardized names to facilitate broader reuse of both the data sets and
the tutorials.
