Aerial Photos 2002: Digital
color infrared (CIR) orthophotography of New Jersey in State Plane NAD83
Coordinates, U.S. Survey Feet. The digital orthophotography was produced at a
scale of 1:2400 (1"=200') with a 1 foot pixel resolution. Digital
orthophotography combines the image characteristics of a photograph with the
geometric qualities of a map. Digital orthophotography is a process which
converts aerial photography from an original photo negative to a digital
product that has been positionally corrected for camera lens distortion,
vertical displacement and variations in aircraft altitude and orientation.
Aerial photography of the entire State of New Jersey was captured during
February-April, 2002. The ortho-rectification process achieved a +/-4.0 ft.
horizontal accuracy at a 95% confidence level, National Standard for Spatial
Data Accuracy (NSSDA). This dataset consists of 5000' x 5000' files in MrSID

Bedrock Aquifers: The
Bedrock Aquifers of New Jersey consists of Geographic Information Systems (GIS)
coverage (shapefile) of the bedrock aquifers and confining units in New Jersey.
The bedrock-aquifer coverage includes fractured-rock aquifers of the Valley and
Ridge, Highlands, and Piedmont physiographic provinces, and aquifers and
confining units of the Coastal Plain physiographic province. The coverage is
generalized to the 1:250,000 scale by eliminating polygons with less than
1,000,000 sq. ft. area (about 23 acres). The data were digitized from various
published and unpublished1:24,000, 1:100,000, and 1:250,000 scale geologic maps
compiled from 1987 to 1993.
Visible Range: 1:12000 and above.
Bedrock
Geology: The Bedrock Geology of New Jersey consists of
statewide data layers (contacts). The GIS data were scanned and digitized from
United States Geological Survey Miscellaneous Investigations and Open-File
Series 1:100,000 scale geologic maps compiled from 1984 to 1993.
Visible Range: 1:12000 and above.

of the Bedrock Geology of New Jersey, which consists of statewide and
countywide data layers (contacts, folds, dikes).
Visible Range: 1:12000 and above.
Bedrock
Outcrops: Bedrock Outcrops of New Jersey shows the extent of
outcropping bedrock materials in northern and central New Jersey exclusive of
the Coastal Plain. Two units are used: one showing where surficial materials
are generally absent and bedrock outcrop is extensive and one showing where
surficial materials are generally less than ten feet thick and bedrock outcrop
is scattered.
Visible Range: 1:12000 to 1:50000.

data shows the elevation of the top of the bedrock or Coastal Plain formations
in areas where the surficial materials are generally more than 25 feet thick.
Visible Range: 1:5000 to 1:250000. Canals and Water Raceways:
New Jersey's canals and water raceways have been important for
transportation and water power for the last 300 years. They have played a
significant role in the economic development of the state. This data shows
locations of current and historic canals and raceways. Where possible, these
have been mapped based on site visits or current aerial photographs. The
location of some abandoned and filled canals and raceways are approximated from
historic maps and photographs and are not guaranteed to be accurate. Some of
the mapped canals and raceways are located on private property with no public
access. Other canals and raceways allow public access on the canal itself or
neighboring pathways, for recreational purposes. The user of this product is
responsible for determining if a canal or raceway is open to the public before
visiting. This data does not include dewatering canals and ditches with two
exceptions, the Berry's Creek Canal and the Old Canal. They were included in
this data because they are navigable. Channelized streams and underground
aqueducts are not included in this data.
Counties: in New Jersey
were gathered from USGS topoquads and other sources in 1987. The scale of the
original data varies, relying primarily on 1:24,000 topoquads.
Visible Range: 1:75000 and above. Dikes:
The Bedrock Geology of New Jersey consists of statewide data layers (dikes).
The GIS data were scanned and digitized from United States Geological Survey
Miscellaneous Investigations and Open-File Series 1:100,000 scale geologic maps
compiled from 1984 to 1993.
Visible Range: 1:5000 to 1:500000. Drought
Regions: Drought regions provide a regulatory basis for
coordinating local responses to regional water-supply shortages. The six
drought regions are based on watershed and water-supply considerations. The
drought regions are designed to assist the DEP in declaring drought warnings
and emergencies in New Jersey during times of decreased precipitation, and
current or anticipated water-supply shortages. By having different regions it
is possible for the State to declare drought warnings or emergencies in
different regions. These warnings and emergencies are declared by the Governor
of the State of New Jersey. The State's response to a drought is coordinated by
the NJDEP Water Supply Administration. Visible Range: 1:5000 and above. Earthquake Epicenters:
This contains earthquakes with epicenters in New Jersey. Most are minor with
magnitudes ranging from 0.4 to 5.3 and depths up to 25km below sea level.

Visible Range: 1:5000 to 1:500000.
Gravity Anomalies (1 mgal):
Gravity anomalies are produced by density variations within the rocks of the
Earth's crust and upper mantle. Mapping of these density variations is the
primary use of gravity anomalies. Gravity Anomalies of New Jersey are bouguer
gravity contours (lines) at 1 milligal intervals. The contours are based on
gravity data in New Jersey and vicinity. The New Jersey contours were clipped
at the state outline.The bouguer anomalies in New Jersey range from a low of
-58 milligals to a high of +37milligals.
Visible Range: 1:5000 and above.
Ground-Water Recharge Areas:
An estimation of ground-water recharge for New Jersey. Ground-water recharge is
estimated using the NJGS methodology from NJ Geological Survey Report GSR-32 "A
Method for Evaluation of Ground-Water-Recharge Areas in New Jersey.
Land-use/land-cover, soil and municipality-based climatic data were combined
and used to produce an estimate of ground-water recharge in inches/year.
Recharge was then ranked by volume (billions of gallons/year) using natural
breaks in the percentage of total volume. Visible Range: 1:5000 to 1:250000.
Landslides: Landslides
in New Jersey contains point locations and other attributes for historic
and recent landslide locations in New Jersey mapped by the New Jersey
Geological Survey (NJGS). The landslides have occurred in the northern and
central part of the state and include slumps, debris flows, rockfalls and
rockslides. Although in New Jersey landslides are not as common as in other
areas of the United States, they are a geologic hazard in areas with steep to
moderate slopes or geologic units prone to failure. They cause damage to
utilities, property, and transportation routes. The average annual direct and
indirect cost of New Jersey landslides is likely in the hundreds of thousands
of dollars. New Jersey landslides have also caused fatalities and injuries.
Visible Range: 1:5000 and above. Magnetic Anomalies (gammas):
Magnetic anomalies are produced by variations in the distribution of iron
minerals, usually magnetite, in the rocks of the Earth's crust. Igneous and
metamorphic rocks can be very magnetic. By comparison, sedimentary rocks are
usually nonmagnetic. Magnetic anomalies therefore provide a way of mapping
exposed and buried crystalline rocks. Magnetic Anomalies of New Jersey are
contours (polygons) at 100 gamma intervals. The contours are based on magnetic
data in New Jersey and vicinity. The aeromagnetic anomalies in New Jersey have
lows ranging from -100 to -200 gammas highs ranging from 900 to 1000 gammas.
Visible Range: 1:5000 and above. Mid-Atlantic States: This
data is a graphical representation showing the state boundaries for New Jersey
and its neighboring states. The data layer is a compilation of data layers from
various state boundary sources.
Visible Range: Always visible.
Municipalities: Municipal
boundaries in New Jersey were gathered from USGS topoquads and other sources in
1987. Since that time, updates to the data have been limited to noting
consolidations of boundaries. The scale of the original data varies, relying
primarily on 1:24,000 topoquads. Visible Range: 1:5000 and above.
Physiographic Provinces:
New Jersey is divided into the Valley and Ridge, Highlands, Piedmont, and
Coastal Plain Physiographic Provinces. Each province defines a region in which
relief, landforms, and geology are significantly different from that of the
adjoining and nearby regions. The boundary between each province is determined
by a major change in topography and geology, and this data set delineates the
boundary lines between them.
Visible Range: 1:5000 and above.
Place Names: This
point layer was extracted from a data set produced by the United States
Geological Survey (USGS), as part of its topographic map data base. Topographic
maps, known as topoquads, are USGS maps that show a wide variety of information
including generalized land use, roads and railroads, streams, political
boundaries and the locations of many kinds of named features, among other
things. For this application, a subset of two types of USGS point features,
Places and Locales, were selected for display. Since many of these named
locations are locally familiar names, they can serve to orient the user to the
map display. For more information of the USGS data set, go to
http://geonames.usgs.gov/.
Visible Range: 1:500000 and below.
Public Community Water Supply Wells:
The Public Community Water Supply (PCWS) Wells contains information for the
wells in New Jersey that supply potable water to public communities. The NJDEP
has cataloged and field located, using the Global Positioning System (GPS), the
PCWS wells as part of the Source Water Area delineation process.
Visible Range: 1:5000 to 1:750000.
Quad Grid: This
shapefile was produced to provide a graphic representation of information that
depicts the statewide grid of quadrangle boundaries of New Jersey.
Visible Range: 1:1000 and above.
Quarries: This data
contains point locations of selected sand, gravel and rock surficial mining
operations in New Jersey. The database contains 1,009 inventoried operations
with 186 being registered with the New Jersey Department of Labor, Office of
Mine Safety and Compliance, and 823 inactive and abandoned surficial mining
operations. One hundred sixty three of the registered mining operations were
located using the Global Positioning System (GPS). With annual production of up
to 20 million tons valued at $100 million, sand, gravel and rock mining is a
significant industry in New Jersey. Inactive and abandoned operations are
included because of their importance in environmental investigations, planning,
zoning and resource evaluation.
Visible Range: 1:5000 to 1:750000.
Roads (Tele Atlas): This
data set represents all roadways, streets, and major highways within the State
of New Jersey in a digital, vector based geographic database format. Streets in
this data set contain address information such as postal codes, street names,
and other routing attributes which may be used for geocoding or route finding.
Visible Range: 1:50000 and below. Sole-Source Aquifers:
There are seven sole-source aquifers (SSAs) in New Jersey. These are defined by
the EPA as those aquifers that contribute more than 50% of the drinking water
to a specific area and the water would be impossible to replace if the aquifer
were contaminated. Sole-source aquifers are defined with guidelines set forth
by the U.S. Environmental Protection Agency (EPA) as authorized in section
1424(e) of the Safe Drinking Water act of 1974. Any federally-funded project in
an area that could affect ground-water in a sole-source aquifer must be
reviewed by the US EPA. This 'project review area' includes the aquifer's
'recharge zone' and it's 'stream-flow source zone'. The recharge zone is the
area through which water recharges the aquifer. The source zone is the upstream
area that contributes recharge water to the aquifer. The EPA sometimes modifies
the project review areas as published in the Federal Register in order to
better protect zone as originally published. Most of New Jersey is covered by
the seven SSAs and their project review areas. The order of chronological
approval is as follows: 1.) Buried Valley SSA 2.) Ridgewood SSA 3.) Rockaway
SSA 4.) Highlands SSA 5.) Northwest New Jersey SSA 6.) Coastal Plain SSA 7.)
Ramapo SSA The sole source aquifer program is a federal program administered by
the Environmental Protection Agency under the Safe Drinking Water Act. All
questions about the program should be addressed to them. EPA's reference for
the sole source aquifers in New Jersey is at:
http://www.epa.gov/region2/water/aquifer/
Surficial Aquifers: The
Surficial Aquifers of New Jersey consists of Geographic Information Systems
(GIS) coverage (shapefile) of surficial aquifers and confining units in New
Jersey. The surfical aquifer coverage includes glacial sediment exceeding 50
ft. thickness in northern New Jersey, and surficial sediment thicker than 50
ft. overlying Coastal Plain aquifers and confining units. The coverage is
generalized to the 1:250,000 scale by eliminating polygons with less than
1,000,000 sq. ft. area (about 23 acres). The data were digitized from various
published and unpublished1:24,000, 1:100,000, and 1:250,000 scale geologic maps
compiled from 1987 to 1993.
Visible Range: 1:12000 and above.
Surficial Geology: The
Surficial Geology of New Jersey shows the extent of surficial geologic
materials in New Jersey. Surficial materials are the unconsolidated glacial,
river, wetland, windblown, marine, estuarine, and hillslope sediments and
weathered rock materials that overlie bedrock and Coastal Plain formations and
that are the parent material for agronomic soils.
Visible Range: 1:12000 to 1:50000.
Surficial Geology Cross-sections:
The Surficial Geology Cross Section Lines are cross sections that show the
extent, thickness, and layering of surficial materials in the subsurface along
the line of section.
Visible Range: 1:12000 and above.
Tidal Benchmark Network:
New Jersey Tidal Benchmark Network consists of point locations and other
attributes for 215 stations. Some point locations are representative of
groupings of tidal benchmarks in a small area. In these cases a central
location was used to show these several benchmarks. The New Jersey Tidal
Benchmark Network consists of 1200 tidal benchmarks along the coast to measure
effects of sea level and shore changes and settle riparian rights disputes. All
locations except one in the layer file are hyperlinked to
njtidalbm.pdf with their Tidal Datums and Benchmark Elevation Sheet to
provide additional information about the benchmarks. Visible Range: 1:5000 and above.
Topographic Images: North, Central and South
sheets: This set of ARC/INFO grids and bit-mapped images is
derived from 14 U.S. Geological Survey 1:100,000- scale, 30 x 60 minute,
digital raster graphic (DRG) images covering the New Jersey region. The grids
were produced to create a set of three seamless and tiled images covering the
north, central and southern parts of New Jersey. The tiles coincide with the
geographic extent of the three sheets for the 1:100,000 scale Geologic Map of
New Jersey, and are intended for use as base maps within a Geographic
Information System (GIS). The conversion of the rasterized topographic-map
images to a bit-mapped, monochromatic mode results in the loss of some map
information otherwise included on full-colored topographic maps, such as area
shading for wooded areas. The output images use an uncompressed
tagged-image-file format (TIFF) and preserve the 250 dots-per-inch resolution
of the DRG source imagery. Each image was processed to clear features outside
tile neat lines and the State boundary. Some map features were set to a
background value prior to conversion to a monochromatic image mode to enhance
image clarity. The images are geo-registered and rectified to the 1983 North
American Datum in state plane coordinate feet. Each image was geo-registered
using at least three links including the corners of each 30 x 60 minute sheet
and 7-1/2' reference tics within New Jersey.

Well Head Protection Areas (Community):
A Well Head Protection Area (WHPA) in New Jersey is a map area calculated
around a Public Community Water Supply (PCWS) well in New Jersey that
delineates the horizontal extent of ground water captured by a well pumping at
a specific rate over a two-, five-, and twelve-year period of time. The area of
capture over two-, five-, and twelve-years is defined using line boundaries and
polygon areas generated with Geographic Information System (GIS). GIS shape
files are produced for each PCWS well and for the set of all PCWS wells in a
county. WHPA delineations are conducted in response to the Safe Drinking Water
Act Amendments of 1986 and 1996 as part of the Source Water Protection Program
(SWAP). The delineations are the first step in defining the sources of water to
a public supply well. Within these areas, potential contamination will be
assessed and appropriate monitoring will be undertaken as subsequent phases of
the NJDEP SWAP. WHPA delineation methods are described in
Guidelines for Delineation of WellHead Protection Areas in New Jersey .
