Download .zipThis ground-water resources theme shows an estimate of sustainable yield available from the aquifers in the area. It was digitized from a paper county map with a scale of 1:63360.

Digitizing used run length encoding techniques, sampling along horizontal lines which represented the midline of cells with a height of 250 ft. The horizontal measurement increment along these lines was one decafoot (10 feet). Additional details of the digitizing process are available on request. The coverage was subsequently converted to an Arc/Info vector format.

A revised version of this map has been completed and is available in hard copy from the Ohio Department of Natural Resources, Division of Water.

Municipal boundaries for Pennsylvania, New Jersey, Maryland, Delaware, and the District of Columbia with ortho-rectified municipal boundaries for the DVRPC Region. Municipal Boundaries have been edited by DVRPC to create a more accurate, seemless regional dataset for the DVRPC region and its surrounding area. This dataset was compiled from multiple sources. Original data sources (in order of drawing rank): DVRPC - for Mercer, Burlington, Camden, Gloucester counties in NJ (an adaptation of NJOIT's Mun Bounds) and Bucks, Montgomery, Philadelphia, Chester, and Delaware counties in PA. In most cases, boundaries have been adjusted to align with parcel data. NJOIT - remaining NJ counties (2008) PennDOT - remaining PA counties (2009) DE State Office of Mgmt & Budget - Delaware municipalities (2002) MD State Hwy Administration - Maryland municipalities (2003) Washington DC - ESRI NOTE: NJ's coast has been clipped or unioned to ESRI's data CD detailed state boundaryDue to a consolidation, Princeton Twp and Princeton Boro in Mercer County, NJ in 2013, the new municipality (named "Princeton"), uses Princeton Boro's unique ID 3402160900. Princeton Township's unique ID (3402160915)no longer exists.Due to the name change from Washington Twp to Robbinsville Twp in Mercer County NJ in 2008, the unique ID (GEOID) for this municipality has changed from 3402177210 to 3402163850 . However, if you download 2000 census data from the Bureau's website, the unique ID (GEOID) for Robbinsville Township will still be 3402177210 in the census data…you will have to manually change its GEOID to 3402163850 in order to get the 2000 data to join to the MCD file correctly.Due to name change from Birmingham Twp to Chadds Ford Twp in Delaware County, PA in 1997, the unique ID (GEOID) for this municipality has changed from 4204506552 to 4204512442.

The classification of land according to what activities take place on it or how it is being used; for example, agricultural, industrial, residential, rural, or commercial. Land use information and analysis is a fundamental tool in the planning process.

DVRPC’s 2020 land use file is based on digital orthophotography created from aerial surveillance completed in the spring of 2020. This dataset supports many of DVRPC's planning analysis goals.

Clipped to Counties - Mapping Area polygon - High resolution land cover dataset for the Delaware River Basin, an area comprised of parts of six counties in the state of New York and four counties in Pennsylvania. Seven land cover classes were mapped: (1) tree canopy, (2) grass/shrub, (3) bare earth, (4) water, (5) buildings, (6) roads, and (7) other paved surfaces. The minimum mapping unit for the delineation of features was set at six square meters. The primary sources used to derive this land cover layer were 2008 LiDAR data and 2010 - 2011 NAIP imagery. LiDAR coverage was complete for the Pennsylvaia portion of the AOI, however, LiDAR was unavailable for large portions of the New York portion. Where LiDAR was not available, imagery was the primary data source. Ancillary data sources included GIS data (eg. such as hydrology, breakline and buildings) provided by the counties of Lackawana, Monroe, Pike and Wayne, PA, as well as the New York State GIS Clearinghouse. Some of these vector datasets were edited by the UVM Spatial Analysis lab through manual interpretation. Other datasets, such as bare soil, were created by the UVM Spatial Anyslsis Lab in order to assist in landcover creation. This land cover dataset is considered current for Pennsylvania portion of the study area as of summer 2010. The dataset is current as of summer 2011 for the New York counties of Chenango, Delaware, Orange and Sullivan. Broome County, NY, is considered current as of summer 2010. Ulster County, NY, employed data from both summer 2010 and summer 2011, therefore currentness varies throughout the county. Object-based image analysis techniques (OBIA) were employed to extract land cover information using the best available remotely sensed and vector GIS datasets. OBIA systems work by grouping pixels into meaningful objects based on their spectral and spatial properties, while taking into account boundaries imposed by existing vector datasets. Within the OBIA environment a rule-based expert system was designed to effectively mimic the process of manual image analysis by incorporating the elements of image interpretation (color/tone, texture, pattern, location, size, and shape) into the classification process. A series of morphological procedures were employed to insure that the end product is both accurate and cartographically pleasing. No accuracy assessment was conducted, but the dataset was subject to a thorough manual quality control.

Download .zipThe soils for Delaware County were converted to tillage groups with differing suitabilities for no-tillage corn production. Criteria were established using Cooperative Extension Service Bulletin 1068, "An Evaluation of Ohio Soils in Relation fo No-Tillage Corn Production.

Soils utilized in this analysis were digitized from the paper original soil survey sheets. These sheets were taped together to form an area covering each of the USGS 7.5 minute quadrangle maps in the county. The areas for each quadrangle were then digitized using run-length encoding technique sampling along horizontal lines which represented the midline of cells with a height of 250 feet. The measurement increment along these lines was one decafoot (10 feet). The quadrangle files were then merged into a county file which has subsequently been converted to Arc/Info format.

The user should bear in mind that this coverage is only an approximation of the soil survey and should not be used for site specific analysis.

Additional details of the digitizing process are available upon request.

Every five years, since 1990, the Delaware Valley Regional Planning Commission has produced a GIS Land Use layer for its 9-county region. In 2000, digital orthophotography was flown by DVRPC. Utilizing this orthophotography, all Land Use annotation and digitizing was performed on-screen, or "heads-up," a first at DVRPC. Digitizing was done using ESRI ArcGIS 8 software at a 1:2400 (1 inch = 200 feet) scale.

Every five years, since 1990, the Delaware Valley Regional Planning Commission has produced a GIS Land Use layer for its 9-county region. As it was in 2000, digital orthophotography was flown by DVRPC in 2005. Digitizing was done using these 2005 true-color aerials on the ESRI ArcGIS software platform at a 1:2400 (1 inch = 200 feet) scale.

Download .zipThis map was derived from the Delaware County Soil Survey using prime farmland map units as provided by Tom Edwards, District Conservationist for Delaware County in combination with land use/ land cover interpreted by the Remote Sensing Unit of The Ohio Department of Natural Resources.

Prime farmland is usually defined as land best suited and available for producing food, feed, forage, fiber, and oilseed crops. It has the soil quality, growing season, and moisture supply needed to produce sustained high yields economically when treated and managed, including water management, according to modern farming methods.

Download .zipCriteria for site selection were based on the "Process Design Manual for Land Treatment of Municipal Wastewater" by the US Environmental Protection Agency, US Army Corps of Engineers, and the US Department of Agriculture, 1977.

A suitable site would meet the following criteria: Permeability- .06-.2 in/hr Slope- 2-8% Depth to Bedrock 1-10 ft Flooding Frequency None

Permeability of the first horizon (about 0-15 in) was not included in the analysis because all Delaware County Soils have unsuitable permeability. Suitabilities are given only for land designated as cropland in the Land use/ land cover inventory.

This analysis is not meant to substitute for an onsite investigation.

Coverages utilized in this analysis were digitized from a mylar county map with a scale of 1:63360, land use on quadrangle maps at a scale of 1:24000 and soil survey maps with a scale of 1:15840. Digitizing used run length encoding techniques, sampling along horizontal lines which represented the midline of cells with a height of 250 ft. The horizontal measurement increment along these lines was one decafoot (10 feet). Additional details of the digitizing process are available on request.

The contour lines illustrate the potentiometric surface much as the contour lines of a topographic map represent a visual model of the ground surface. A potentiometric surface map is very similar to a water table map in that both show the horizontal direction and gradient of ground water flow.Contact Information:GIS Support, ODNR GIS ServicesOhio Department of Natural ResourcesDivision of Geological Survey2045 Morse Rd, Bldg I-2Columbus, OH, 43229Telephone: 614-265-6693Email: gis.support@dnr.ohio.gov
