General usage information

The data is divided in a number of Arc Info export format coverages. Each
of these coverages may contain a number of thematic feature classes. Each
feature class may contain one or more different types of features which may
have different attributes. Where applicable the coding scheme and attribute
items conform to the FACC digest standard. In some cases it was necessary
for us to derive new f_codes and attributes in order to code all the
features in our covers. Those f_codes and attributes that have been added
will be documented in appendix II. For all other attributes we would like
to direct our users to the digest standard website online at
http://www.digest.org.



The data has been organised into different Arc/Info coverages. These relate
to, but do not exactly correspond to the original VMAP0 coverages. Within
each coverage there may be a number of thematic feature classes. For
instance roads and railroads are both within the transportation coverage.

Appendix I lists each arc info coverage, the feature classes it contains
and all relevant attribute fields and their meanings. There may be
additional fields in the data but these are for GeoAccess internal use, and
may be ignored by users.
