scribe coated sheet. The map is copied on
a film from which several strip masks are
made. The final manuscript is then pro-

proofreading the map is printed.
Revision criteria and methods are in the
planning stages. The wegetation cower
has changed considerably in some of the
areas which were mapped 15—20 years

The main objective of the mapping
program has been to provide a basis for
land evaluation for agricultural purposes.
The vegetation maps are also valuable
tools for the planning and monitoring of
other land use, for the analysis of en-
vironmental problems and they will also
serve as a historical record in the future.
