The primary digital orthophotoquad (DOQ) is a 1-meter ground resolution, quarter-quadrangle (3.75-minute of latitude and 3.75-minute of longitude) image cast on the Universal Transverse Mercator Projection (UTM) on the North American Datum of 1983 (NAD83). The normal orientation data is by lines (rows) and samples (columns). Each contains a series of pixels ordered from west to with the order of the lines from north to south. The radiometric image values are stored as 256 gray levels ranging 0 to 255.Purpose:Digital orthophotos serve a variety of purposes, from interim maps to references for earth science investigations and. The images are useful as a layer of a geographic information system and as a tool for revision of digital graphs and topographic maps.These data are prepared for use by the Natural Resources Conservation Service for USDA Service Center personnel to administer agency programs.Time_Period_of_Content:Time_Period_Information:Range_of_Dates/Times:Beginning_Date: 19940317Ending_Date: 19940424Currentness_Reference: ground conditionStatus:Progress: CompleteMaintenance_and_Update_Frequency: As neededSpatial_Domain:Bounding_Coordinates:West_Bounding_Coordinate: -83.763583East_Bounding_Coordinate: -83.106265North_Bounding_Coordinate: 39.766002South_Bounding_Coordinate: 39.236672Keywords:Theme:Theme_Keyword_Thesaurus: NoneTheme_Keyword: digital orthophotoTheme_Keyword: digital image mapTheme_Keyword: aerial photographTheme_Keyword: rectified photographTheme_Keyword: rectified imageTheme_Keyword: orthophotoTheme_Keyword: DOQTheme_Keyword: DOQQPlace:Place_Keyword_Thesaurus:Counties and County Equivalents of the States of the United States and the District of Columbia (FIPS Pub 6-3)Place_Keyword: Fayette CountyPlace_Keyword: OhioPlace_Keyword: United StatesAccess_Constraints: None.Use_Constraints:These data were prepared for Official Use Only by USDA employees as part of the Service Center Initiative.Point_of_Contact:Contact_Information:Contact_Organization_Primary:Contact_Organization:U.S. Department of Agriculture, Natural Resources Conservation ServiceContact_Person: Geospatial Data BranchContact_Address:Address_Type: mailing and physical addressAddress: Federal Center, 501 W.

Radiometry is verified by USGS through a visual inspection of the digital quadrangle with the original unrectified image to determine if the digital orthophoto has the same or better quality as the original unrectified input image. Radiometric differences can be detected adjacent DOQ files due primarily to differences in photography capture dates and sun angles of aerial along flight lines. These differences can be in an image's general lightness or darkness when compared to adjacent DOQ file coverages.Logical_Consistency_Report: Not ApplicableCompleteness_Report:All DOQ image mosaics are visually inspected for completeness to ensure the area of interest is included. Original images are almost entirely cloud free. Source photography is leaf-off in deciduous vegetation regions. Void areas having a radiometric value of zero and appearing black may exist.Positional_Accuracy:Horizontal_Positional_Accuracy:Horizontal_Positional_Accuracy_Report:The horizontal positional accuracy and the assurance of that accuracy depend, in part, on the accuracy of the data inputs to the rectification process. These inputs consist of the digital elevation model (DEM),aerotriangulation control and methods, the photo source camera calibration, scanner calibration, and aerial photographs that meet National Aerial Photography Program (NAPP) standards. The vertical accuracy of the verified USGS format DEM is equivalent to or better than a USGS level 1 or 2 DEM, with a root mean square error (RMSE) of no greater than 7.0 meters. Field control is acquired by third order class 1 or better survey methods sufficiently spaced to meet National Map Accuracy Staandards (NMAS) for 1:12,000-scale products. Aerial cameras have current certification from the USGS, National Mapping Division, Optical Science Laboratory. Test calibration scans are performed on all source photography scanners. Horizontal positional accuracy is determined by the Orthophoto Accuracy (ORACC) software program for DOQ data produced by the National Mapping Division. The program determines the accuracy by finding the line and sample coordinates of the passpoints in the DOQ and fitting these to their ground coordinates to develop a root mean square error (RMSE). From 4 to 9 points are checked. As a further accuracy test, the image line and sample coordinates of the DEM corners are transformed and compared with the actual X,Y DEM corner values to determine if they are within the RMSE. Additional information on this testing procedure can be found in U.S. Department of the Interior, U.S. Geological Survey, 1993, Technical Instructions, ORACC Users Manual (draft): Reston, VA. Adjacent DOQ's, when displayed together in a common planimetric coordinate system, may exhibit slight positional discrepancies across common DOQ boundaries. Linear features, such as streets, may not be continuous. Field investigations to validate DOQ positional accuracy reliabilty are periodically conducted by the USGS, National Mapping Division, Geometronics Standards Section. DOQ's produced by cooperators and contractors use similarly approved RMSE test procedures.Quantitative_Horizontal_Positional_Accuracy_Assessment:Horizontal_Positional_Accuracy_Value: 7 metersHorizontal_Positional_Accuracy_Explanation:U.S.Bureau of the Budget, 1947, United States National Map Accuracy Standard.Vertical_Positional_Accuracy:Vertical_Positional_Accuracy_Report: NALineage:Source_Information:Source_Citation:Citation_Information:Originator: U.S. Geological SurveyPublication_Date: UnknownPublication_Time: UnknownTitle: DOQQGeospatial_Data_Presentation_Form: remote-sensing imagePublication_Information:Publication_Place: Reston, VAPublisher: U.S. Geological SurveySource_Scale_Denominator: 40,000Type_of_Source_Media: CD-ROMSource_Time_Period_of_Content:Time_Period_Information:Range_of_Dates/Times:Beginning_Date: 19940317Ending_Date: 19940424Source_Currentness_Reference: ground conditionSource_Citation_Abbreviation: DOQQSource_Contribution:Panchromatic black and white (or color infra-red) NAPP or NAPP-like photographs.

The majority of DOQ datasets are acquired through government contract. The process step describes, in general, the process used in the production of USGS DOQ data sets. The rectification process requires, as input, a user parameter file to the rectification process, a digital elevation model gridded to specified bounds, projection, zone, datum and X-Y units, a scanned image file covering the same area as the DEM, ground X-Y-Z point values and their conjugate photo coordinates in the camera coordinate system, and measurements of the fiducial in the digitized image.The camera calibration report provides the length of the camera and the distances in millimeters from the optical center to the camera's 8 fiducial marks. These marks define the field of reference for spatial measurements made from the photograph. Ground control points acquired from ground surveys or developed in aerotriangulation, are third order class 1 or better, and meet National Map Accuracy Standard (NMAS) for 1:12,000-scale. Ground control points are in the Universal Transverse Mercator or the State Plane Coordinate System on NAD83. Horizontal and vertical residuals of aerotriangulated tie-points are equal to or less than 2.5 meters. Standard aerotriangulation passpoint configuration consists of 9 ground control points, one near each corner, one at the center near each side and 1 near the center of the photograph, are used. The conjugate positions of the ground control points on the photograph are measured and recorded in camera coordinates.The raster image file is created by scanning an aerial photograph film diapositive with a precision image scanner. An aperture of approximately 25 to 32 microns is used, with an aperture no greater than 32 microns permitted. Using 1:40,000-scale photographs, a 25-micron scan aperture equates to a ground resolution of

Download .zipThe B Law Coal Permit Maps county coverage sets were developed using the original mine maps for coal mining and reclamation permits issued under Ohio law from 1973 through 1976. Approximately 1285 B-Permits were issued during this time period, however, only approximately 414 records could be located and captured at this time. The Division of Mineral Resources Management will continue to search for missing B permit archival records as resources allow; additional B permit data may be added to this existing coverage in the future.

Ohio started issuing coal mining licenses in the 1940s. The earliest license and permit requirements were minimal and sometimes did not include submittal of a map or other delineation of the mined area. Significant changes to legal requirements are reflected by the alphabetical designation of each subsequent law revision, i.e., earlier A-law permits (circa 1966) through contemporary D-law permits. The ODNR-Division of Mineral Resources Management (DMRM) has attempted to create as complete a database as possible from available archive records, however, research has identified missing permit files. Thus, this GIS data is known to be incomplete due to the loss of archival records.

The B law permit maps were scanned at a density of 200 dots per inch (dpi). The scanned image was then heads-up digitized using Microstation computer aided design software (CAD) to create design files grouped by county location. Data captured within the design file includes permit boundary, affected boundary, test hole locations, and associated attributes. The design file was then "placed-to-ground" using ODNR Division of Geological Survey's "ODNR Land Subdivision Background Design Files" NAD83 State Plane coverages and DOQQ aerial images obtained through the Ohio Geographically Referenced Information Program (OGRIP)/Ohio Department of Administrative Services. The design file was then converted to ARC/INFO coverage and projected to State Plane Ohio Coordinates, NAD83:

Download .zipThe A Law Coal Permit Maps county coverage sets were developed using the original mine maps for coal mining and reclamation permits issued under Ohio law from approximately 1966 through 1973. Approximately 1111 A-Permits were issued during this time period, however, only 350 records could be located and captured at this time. The Division of Mineral Resources Management will continue to search for missing A permit archival records as resources allow; additional A permit data may be added to this existing coverage in the future.

Ohio started issuing coal mining licenses in the 1940s. The earliest license and permit requirements were minimal and sometimes did not include submittal of a map or other delineation of the mined area. Significant changes to legal requirements are reflected by the alphabetical designation of each subsequent law revision, i.e., earlier A-law permits (circa 1966) through contemporary D-law permits. The ODNR-Division of Mineral Resources Management (DMRM) has attempted to create as complete a database as possible from available archive records, however, research has identified missing permit files. Thus, this GIS data is known to be incomplete due to the loss of archival records.

The A law permit maps were scanned at a density of 200 dots per inch (dpi). The scanned image was then heads-up digitized using Microstation computer aided design software (CAD) to create design files grouped by county location. Data captured within the design file includes permit boundary and affected boundary and associated attributes. When available, test hole locations and associated attributes were also captured. The design file was then "placed-to-ground" using ODNR Division of Geological Survey's "ODNR Land Subdivision Background Design Files" NAD83 State Plane coverages and DOQQ aerial images obtained through the Ohio Geographically Referenced Information Program (OGRIP)/Ohio Department of Administrative Services. The design file was then converted to ARC/INFO coverage and projected to State Plane Ohio Coordinates, NAD83:

Projected coordinate system name: NAD_1983_StatePlane_Ohio_South_FIPS_3402_Feet or NAD_1983_StatePlane_Ohio_North_FIPS_3401_Feet

A complete county coverage set consists of three data files for the permit area, affected area, and test hole locations. For example, the coverage for Harrison County includes:

harrison_a_permitted (Harrison County, A-permit area polygons) harrison_a _affected (Harrison County, A-permit affected area polygons) harrison_testholes_a (Harrison County, Test Hole points)
