Goddard noted that
Pennsylvania is one of the
first states in the nation to
have a complete land use
survey using the
sophisticated new
techniques devised by the
U S.Geological Survey.
The LUI >A (land Use
Data Analysis) program was
introduced by the U.S G.S. in
1974. Utilizing the latest
photo imagery available
from high altitude planes,
the land use and land cover
classification system can
recognize and delineate as
many as 37 separate land use
categories, some for areas
as small as 10 acres. The
scale of the final maps which
have been prepared is 1-
250,000 or approximately one
inch on the map equalling
four miles on the ground,

Recognizing the potential
benefits to the Com
monwealth and its various
planning and economic
programs, DER’s Bureau of

Topographic and Geologic
Survey, with the cooperation
of the Bureaus of En
viommental Planning and
systems Management,
worked to arrange a
cooperative agreement with
the U.S.G.S. in 1975 to
prepare, land use and land
cover maps for all of Penn
sylvania.
For this project, Penn
sylvania was divided into 14
subdivisons each of which
corresponded to a standard
1-2500,000 scale topographic
base map.
For each of the 14 base
maps, six overlays were
compiled including the land
use and land cover map
which identifies 30 different
categories of land use. Other
overlays show county
boundaries, river basin
boundaries, State land
• areas, Federal lands and
county census subdivisions.
One of the most important
aspects of this new mapping
program is that the data

have been digitized and
placed on magnetic tapes so
they can be sorted in a
computer,
analyzed in various ways.
The data also can be updated
readily as newer information
becomes available in future
years.
Changes in land use will be
identifiable, both in type and
quantity. With the data
digitized, it will be possible
to enter other map data into
the system and print
overlays of other mappable
characteristics. Thus, local,
state or regional users of
land use data will be able to
update and add new
categories of data or devise
systems for subdividing the
existing categories.
In announcing completion
of the land use maps, God
dard noted they can be a
valuable tool or anyone
involved in comprehensive
land use planning. These
maps and data should
benefit State and local

government agencies,
transportation planners,
industry, energy planners,
agriculture, conservation
groups and recreation
agencies.
The initial 98 maps and
overlays being delivered by
the U.S.G.S (seven for each
of the 14 subdivisions) will be
housed and maintained at
the Bureau of Topographic
and Geologic urvey, 914
Executive House, Second
and Chestnut Streets,
Harrisburg, the maps will be
available for review and
inspection at the Bureau
offices and may be copied at
the users expense.
The digitized data on
computer tapes from which
the map was plotted will be
finished in approximately
three months and will be
housed and made available
through the Bureau of
