[GRASS-dev] Question on r.grow 'metrics' parameters

[Patton, Eric]

I was wondering if anyone could describe, or point me to a link of, the various r.grow metrics parameter definitions: euclidian, maximum, and manhattan.

Also, are the comments regarding how r.grow decides how to grow between two equally eligible cells here (http://www.nabble.com/-GRASSLIST%3A7611--r.grow-to8629593.html#a8629593) still valid? I would like to add this information to the docs, and AFAICS, main.c hasn't changed much since Glynn's last edit 21505 back in late November, 2006.

Thanks,

~ Eric.
