All: I have used r.lake to simulate flood inundation in an urban area -- the raster looks great! What I want to do (and have done) is to use r.to.vect, export the vector as a KML (which works), bring the simulated flood inundation map KMLs into GoogleEarth and create some animations from the simulated inundation, including showing rising flood levels inundating the city streets in 3D.
I can basically do all this, except that the r.to.vect conversion creates a gazillion boxes that are the size of the raster pixels -- I don't want all the tiny boxes. What I want, is just a single (albeit, complex) polygon showing the flooded areas. v.dissolve will remove the boundaries of adjacent boxes if their cat or attributes are the same -- is this the way to go, namely, make all the cats or attribute values the same and then use v.dissolve? Or, is there is there a better way to do what I'm attempting to do? That is, is it best to keep the individual small vector boxes for reasons I'm not considering? Thank you, Tom --
