Three coverages are provided for each county:

<county>1 - polygon coverage showing census block geography
<county>2 - point coverage containing polygon centroids to use with
            <county1>
<county>3 - point coverage of landmarks


Internal documentation is provided for all coverages.

In addition to the internally-provided records, note that
in approximately 5% of the state (and particularly around
the Ossipee area), the linework has been adjusted to
match more closely with pre-existing GRANIT data.
