4. LiDAR Coverage, by County
Table above lists
coal field counties
with 100%
coverage as a
result of WVDEP’s
LiDAR flights (the
exception is
Marion which flew
their own mission
but shared the
data with WVDEP
via WVU NRAC).
Table top right counties shows additional counties with zero to partial LiDAR coverage as of Autumn 2011 as
a result of WVDEP’s LiDAR work. Each county lists its corresponding percentage of total coverage.
Additional counties confirmed to have county wide LiDAR are Cabell, Jefferson, Kanawha and Raleigh with
new county-wide coverage in 2011. There may be more in the northern or eastern panhandles.

9. Resolution and Change Comparison
WVDEP 2009
Data
At this scale, differences in data resolution and change over time are not widely noticeable. However, upon
further analysis, significant differences in resolution and change become evident, as shown in the next slide…

10. Resolution and Change Comparison
The image above is
WVDEP 2009
Data a portion of the most
recent LiDAR flown
by West Virginia
University (WVU) for
WV Department of
Environmental
Protection (WVDEP).
The image below is a
portion of the data
Change in Landscape provided by the West
Virginia Statewide
Addressing and
Mapping Project
Change in Resolution (WVSAMP). Both
examples are from
the same region in
Boone County, West
Virginia. Changes to
the landscape that
have occurred since
the date of data
collection by
WVSAMP versus the
date of collection
from the WVDEP
LiDAR are clearly
visible. This
comparison also
shows the
considerable
WVSAMP 2003 improvement in
Data
resolution between
the two datasets.

14. LiDAR, Blair Mountain, and Viewshed Analysis
WVDEP’s first official use of this LiDAR data
was a viewshed analysis investigating
existing and proposed mining permits around
Blair Mountain.
