Hi, I'm trying to determine the default method of rasterization used by v.to rast.
In the v.to.rast manual it states in relation to the -d option, that 'All cells touched by the line will be set, not only those on the render path', but I'm not certain which method is being used by default. I came across a paper by Biagi and Negretti <http://geomatica.como.polimi.it/workbooks/n2/articoli/lbmn.pdf> * which describes how by default vectors are rasterized in GRASS 5. The latter authors refer to the 'center' method as being the standard GRASS command in 5.0 (p. 4). Is this used in GRASS 7? From my observation (in the Map Display), by default, vector area appear to be rasterized if the center of the grid cell falls within the area boundary? I haven't checked through the code, but maybe someone has some knowledge on the history of v.to.rast?
