New_Jersey_1971_78_Digitized_Shoreline.zip features a digitized historic shoreline for the New Jersey coastline (Point Pleasant, NJ to Longport, NJ) from 1971 to 1978. Imagery of the New Jersey coastline was acquired from the New Jersey Geographic Information Network (NJGIN) as two images: “1970 NJDEP Wetlands Basemap” (1971-78) and the “1977 Tidelands Basemaps” (1977-78). These images are available as a web mapping service (WMS) through the NJGIN website (https://njgin.state.nj.us/NJ_NJGINExplorer/jviewer.jsp?pg=wms_instruct). To reduce digitizing error, the imagery was acquired on a hard drive from the NJGIN via personal communication. Using ArcMap 10.3.1, the "1970 NJDEP Wetlands Basemap" was used to delineate and digitize historical foreshore, backshore, mainland, and island shoreline positions, with the “1977 Tidelands Basemaps” being used to fill in missing shorelines and clarify areas of uncertainty from the 1970s imagery. These shorelines were digitized for use in long-term shoreline and wetland analyses for Hurricane Sandy wetland physical change assessment.

Prior to the year 2000, DVRPC’s aerial imagery consisted of mylar aerial photo enlargements or “atlas sheets”. These atlas sheets were produced from 9x9" aerial photos. The imagery dates from the years 1959, 1965, 1970, 1975, 1980, 1985, 1990, & 1995. The 1959s and 1965s primarily cover the urbanized portion of the DVRPC region (the DVRPC region is made up of nine counties: Bucks, Chester, Delaware, Montgomery, and Philadelphia in Pennsylvania; Burlington, Camden, Gloucester, and Mercer in New Jersey). Subsequent years provide full coverage of the region, minus the occasional missing scan. In order to increase the efficiency of using the historical aerial imagery, the sheets were scanned into TIFF (Tagged Image File Format) files. Each TIFF file ranges between 35- 40MB in size. Unlike DVRPC’s more recent aerial imagery (2000 and later), the historical aerials are not “orthorectified” or “orthocorrected”. In other words, they are simply aerial images with no spatial reference or uniform scale. Through the process of georeferencing, Montgomery County GIS assigned a spatial reference which will enabled them to be used more readily in a GIS environment. That said, georeferencing is not orthorectifying or orthocorrecting. What it does allow is for the scan to be displayed relative to other spatially referenced GIS layers. A georeferenced scan does not have the properties of an actual orthoimage. Whereas an orthoimage can be used for making accurate measurements, a georeferenced image cannot, as it does not have the spatial accuracy and uniform scale of an orthoimage.

Assessing the physical change to shorelines and wetlands is critical in determining the resiliency of wetland systems that protect adjacent habitat and communities. The wetland and back-barrier shorelines of New Jersey changed as a result of wave action and storm surge that occurred during Hurricane Sandy, which made landfall on October 29, 2012. The impact of Hurricane Sandy will be assessed and placed in its historical context to understand the future vulnerability of wetland systems. Making these assessments will rely on data extracted from current and historical resources such as maps, aerial photographs, satellite imagery, and lidar elevation data, which document physical changes over time. This USGS Data Series publication includes several open-ocean shorelines, back-island shorelines, back-island shoreline points, sand area polygons, and sand lines for the undeveloped areas of New Jersey that were extracted from orthoimagery (ortho aerial photography) dated from March 9, 1991 to July 30, 2013. This data-set consists of lines that comprise the inland extent of the main body of sand (beach/dune/overwash area) found in the orthoimagery taken on the date specified in the filename and in the "Date_" field in the feature attribute table. They are based on the sand area polygons, nj_sandpo_*.shp, that are included in this Data Series publication and can be accessed via the Data Download page. Orthoimagery of New Jersey were acquired in digital format from U.S. Department of Agriculture (USDA), U.S. Geological Survey (USGS), National Oceanic and Atmospheric Administration (NOAA), and New Jersey Geographic Information Network (NJGIN). The following list provides additional details about the orthoimagery used. The sand lines are organized by area with all dates for each area compiled into one data-set (shapefile) named nj_sandln_

This index represents the coverage of the scans of DVRPC's non-orthorectified, mylar, aerial photo enlargements.. These polygons were developed to define the overall extent of the imagery, and to assist users in locating the particular images of interest to them.This layer includes a "STATUS" attribute field that indicates what scans are missing, however this is not a complete inventory of missing scans.Prior to the year 2000, DVRPC’s aerial imagery consisted of mylar aerial photo enlargements or “atlas sheets”.

The wetlands polygons included in this data set are extracted from the Land Use 2002 layer. Displayed are all polygons that have a TYPE02 code of 'WETLANDS'. While these wetland delineations are not regulatory lines, they represent important resource data in identifying potential wetland areas. These wetland data have a somewhat involved delineation history. Non-tidal wetlands were first mapped in a separate effort under the Freshwater Wetlands Mapping Program (FWW), based on 1986 photography. Although the original FWW maps were produced as a separate data set, they were incorporated into a state wide composite land use/land cover (LU/LC) data set also being initially mapped from the 1986 photography. The FWW delineations were integrated into the LU/LC data layer in their entirety as originally delineated, with all line work and coding intact. The tidal wetlands were being mapped as part the LU/LC mapping effort itself. This integrated data set, including the FWW delineations, and the remaining land use/land cover delineations for areas outside of the FWW polygons, which included tidal wetland areas, became the initial 1986 LU/LC layer for the NJDEP. Beginning in 1995, NJDEP acquired new aerial imagery, and began updating the initial integrated LU/LC layer from 1986 based on this newer imagery. The 1986 layer was examined with the new imagery, and areas of change delineated, with any new line work and land use codes needed to map the changes added to the base data set. This updated LU/LC layer is identified as Land Use 1995 in this application. Included in the change analysis were any non-tidal wetland polygons mapped in the original FWW mapping effort, as well as any tidal wetland polygons mapped in the 1986 LU/LC mapping effort. More recently, new photography was acquired in the spring of 2002, and this photography was used in a second land use update project. The Land Use 1995 layer was examined over the 2002 imagery, and an updated layer based on the 2002 imagery was created, available in this application as 'Land Use 2002'. The layer displayed here is the selection of all wetlands, both tidal and non-tidal, as included in that 2002 land use layer. As with all original wetland delineations delineations, this data set is intended to serve as a resource for analysis rather than regulatory delineations. The NJDEP may change the line work of any wetlands polygon based on more in depth analysis and field inspection for regulatory purposes.

This OGC compliant Web Map Service includes a historical image data set of a mosaic of black and white photography of New Jersey from the early 1930s. The source imagery was hand cut to produce 261 mosaic tile prints on linen-backed paper. The data set for this service was produced by scanning these mosaic tile prints at 400 dpi and saved as TIFF images. The scanned TIFF images had an approximate pixel resolution of 6.5 feet. They were georeferenced against 1995/97 color infrared digital orthophotography. The georeferenced TIFFs were clipped and converted into other image formats. The digital product has not been corrected for distortion or vertical displacement. They do not meet the National Standard for Spatial Data Accuracy (NSSDA).

This data set contains ortho-rectified mosaic tiles, created as a product from the NOAA Integrated Ocean and Coastal Mapping (IOCM) initiative. The source imagery was acquired from 20110716 - 20110716. The images were acquired with an Applanix Digital Sensor System (DSS). The original images were acquired at a higher resolution than the final ortho-rectified mosaic. Ortho-rectified mosaic tiles are an ancillary product of NOAA's Coastal Mapping Program (CMP), created through a wider Integrated Ocean and Coastal Mapping initiative to increase support for multiple uses of the data.

Data are in .tif format with associated .his (HIStory), browse graphic (.jpg), and metadata (.html and .txt) files. The metadata utilize the Federal Geographic Data Committee (FGDC) format. The ground sample distance (GSD) for each pixel is 0.35 m.

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 product contains a Geographic Information System (GIS) ESRI polygon shapefile of the canals and raceways, with selected attributes. It also comes with an associated database file, projection file and metadata. The shapefile and metadata are compressed as a .zip file for download. 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 shapefile. The New Jersey Geological Survey is interested in updating this product. Please send information on canals and raceways not shown here to njgsweb@dep.nj.gov. Please include specific site locations and, if possible, an aerial image or map.

Data are of numbers of breeding pairs of Adelie penguins(Pygoscelis adeliae)in the Ross Sea region colonies counted from aerial photographs. Photographs were taken from either a helicopter or from a C-130 Hercules. Photos were printed, populations counted, catalogued and filed. Since 2004, digital photography was used and in 2011 semi-automatic penguin counting software was developed to speed up the counting and validation process. Ross Island colonies were censused annually, colonies along the Victoria Land coast were censused as logistics allowed. Data collection started in 1981 in response to a proposed krill fishery and is ongoing. The aim was to locate all Adelie penguin colonies in the Ross Sea Region, and to count the numbers breeding at each from aerial photographs. The work attempts to relate annual changes in numbers of penguins breeding and their breeding success to weather, sea ice and other climate parameters in order to distinguish between responses due to natural events and those induced by commercial exploitation (such as fishing) or human disasters. A total of 39 colonies were found in the Ross Sea. The work is ongoing.

The "Brownfield and Contaminated Site Remediation Act" (N.J.S.A. 58:10B-1 et seq.) requires the Department of Environmental Protection to map regions of the state where large areas of historic fill exist and make this information available to the public. This GIS layer depicts areas of historic fill covering more than approximately 5 acres. For the purposes of this layer, historic fill, as defined at N.J.A.C. 7:26E-1.8, means, “non-indigenous material, deposited to raise the topographic elevation of the site, which was contaminated prior to emplacement, and is in no way connected with the operations at the location of emplacement and which includes, without limitation, construction debris, dredge spoils, incinerator residue, demolition debris, fly ash, or nonhazardous solid waste. Historic fill material does not include any material that is substantially chromate chemical production waste or any other chemical production waste or waste from processing of metal or mineral ores, residues, slag or tailings. In addition, historic fill material does not include a municipal solid waste landfill site.” The information in the layer makes no determination whether the material was contaminated prior to emplacement. This layer can be used as one line of evidence for an investigator’s professional judgment in determining that historic fill is present at a site; however, an investigation must still be completed in accordance with the Technical Requirements for Site Remediation at N.J.A.C. 7:26E-4.7. Also see the Historic Fill Technical Guidance for more information regarding the investigation and remediation of historic fill at: https://dep.nj.gov/srp/guidance/. This data was mapped at a scale of 1:24,000 (1 inch represents 2000 feet) and is not intended for use at more-detailed scales. Fill was mapped from stereo aerial photography taken in March 1979, supplemented in places by planimetric aerial photography taken in the spring of 1991 and 1992. Additional areas of fill were mapped by comparing areas of swamp, marsh, and floodplain shown on archival topographic and geologic maps on file at the N. J. Geological Survey, dated between 1840 and 1910, to their modern extent. In a few places, fill was mapped from field observations and from drillers’ logs of wells and borings. Most urban and suburban areas are underlain by a discontinuous layer of excavated indigenous soil mixed with varying amounts of non-indigenous material. This material generally does not meet the definition of historic fill and is not depicted on this map. Also, there may be historic fills that are not detectable on aerial photography or by archival map interpretation and so are not shown on this map, particularly along streams in urban and suburban areas. As of this January 2016 edition, twelve new quadrangles were added to the statewide coverage. They are Allentown, Beverly-Frankford, Brookville, Canton-Taylors Bridge, Chatsworth, Forked River- Barnegat Light, Indian Mills, Keswick Grove, Lambertville, Millville, and Woodmansie. As of this March 2025 edition, eight new quadrangles were added to the statewide coverage. They were Cassville, Lakehurst, Oswego Lake, Jenkins, Atsion, Bridgeton, Whiting, and Lakewood. Seven quadrangles have been revised. They are Trenton East, Trenton West, Pennington, Lambertville, Rocky Hill, Ship Bottom, Point Pleasant, and Califon.

This data set was created as part of a project to improve and update the delineation of the State boundary between New Jersey and Pennsylvania. Exhaustive work was carried out using available aerial imagery from various time periods, several decades of USGS Topo maps, tax maps and other historical maps. This included portions of the original map surveyed for the 1786 bi-state commission report to determine which islands from the report still exist and could be identified. Several islands were found to no longer exist because accretion of deposited materials filled in the area between island and mainland or the island disappeared under the river’s surface through erosion. In addition, many of the islands are no longer known by the names listed in the 18th century report and had to be cross-referenced between maps of various vintages and other historical information.
