Checking a raster map about null values i get results that seem non consistent:
the map is a result from r.mapcalc (1 for null and 0 for all othe values)
r.info min = 0 max = 1
r.stats
0 775…
* 805….
r.info claims max value is 1
r.stats no cell with value 1
maybe i do not

r.stats honours the current region, r.info doesn't.
If your map's data area would be in Europe and your current region is by
mistake defined somewhere in the middle of Canada: r.stats would report all
values to be NULL.
Dear all,
If you are as fond of the upcoming GRASS 7 version as I am and if you - like me
- whish to see this brilliant version released rather today than tomorrow, I
would like to invite you to consider supporting the devs at the GRASS Community

Thank’s for the replay Hermann,
this is not the case AFAIK because i generated the map using r.mapcalc
with region and MASK properly set …

Hello,
I wrote a tutorial on how to go from a TIGER road map and GTFS data to a
topological analysis of bus stops. There are some minor formatting
issues I'm working on, but was hoping to get technical or other feedback
on it.
