[GRASS-user] fill in null areas equal to nearest value

[Janet Choate]

Hello GRASS community,
I have two maps - where one map is slightly larger than the other - so that
the smaller map is missing data just around the edges based on the outline
of the larger map.
The smaller map is a map of floating point values, the larger map has a
single value of 1.
I would like to fill in the missing edge data of the smaller map based on
the outline of the larger map - setting the null areas to the nearest value
in the smaller map.

Thank you for any advice!
Janet
