Dear List,
I have a question which often makes me crazy but finaly I decided to solve
it.
So, I have two polygon coverages of land cover from 1990 and 2000. The one
from 2000 is made on the base of 1990 and only some areas where there is a
chage in the land cover new polygons have been made. The rest of the two
coverages is completely the same. They overlap very well whithout chages in
the polygon boundaries.
The problem beggin when I cleaned them (in ArcInfo) (I had to do this
because there was not good topology build). I used the minimum value for
dangle and fuzzy, but later when I open them I saw that they are a lot of
changes in the boundaries of the first coverage which do not occur in the
second coverage and vice versa.
Is there a way to snap later these two coverages automaticaly using some
very small tolerance because the changes are realy small but "not pretty". I
have ArcGIS 8.3.
The scale of the coverages is 1:100K and the changes are not more then 10m.
Thank you very much in advance,
V. Vassilev
