Description:
Abstract: Digital orthophotography of New Jersey, distributed as an Open Geospatial Consortium compliant Web Map Service (WMS). The map service includes an image data set of digital color infrared orthophotography of New Jersey from 2002. The native data set spatial reference system is State Plane Coordinate System NAD83 Coordinates, U.S. Survey Feet. In most client software, the default spatial reference system of the service will be Geographic Coordinates, WGS84. Several other coordinate systems are supported (see Supplemental Information; and the Distribution Information section). 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. The imagery was captured at a negative scale of 1" = 1600' in the spring of 2002, under leaf-off conditions, on color-infrared film. The ortho-rectification process has achieved a +/-4.0 ft. horizontal accuracy at a 95% confidence level, National Standard for Spatial Data Accuracy (NSSDA). The final product has a nominal scale of 1:2400. The georeferenced TIFF tiles delivered to the State of New Jersey were then converted to lossless JPEG2000 files, which are used in this service. HOWEVER, the Web Map Service does not have exactly the same spatial accuracy as the original imagery, due to resampling. Files of the 2002 digital orthophotography are available in several other formats, including downloadable MrSID tiles from the New Jersey Image Warehouse, and both TIFF images and MrSID images on hard media from the EROS Data Center. See separate metadata record for the MrSID data for details.
Purpose: This service was created to provide convenient internet access to 2002 orthophotos. It can be used by anyone with internet access and client software that can consume Open Geospatial Consortium compliant Web Map Services (WMS). The data provide aerial survey of the State of New Jersey. Orthophotos serve a variety of purposes, from interim maps to field references for earth science investigations and analysis. The digital orthophoto is useful as a layer of a geographic information system and as a tool for revision of digital line graphs and topographic maps.
Supplemental Information: This Web Map Service is intended to replace the original WMS of this imagery, which was published by NJOIT OGIS in 2007. In addition to the default spatial reference, this service supports requests for data delivered natively in the following coordinate reference systems: EPSG::3424 NAD83 NJ state plane feet EPSG::2959 UTM zone 18N EPSG::4269 Geographic NAD83 EPSG::4326 Geographic WGS84 EPSG::102711 NAD83 NJ state plane feet, ESRI The images supplied by this map service do not have exactly the same spatial accuracy as the original imagery, due to resampling during WMS processing. Visual inspection by OGIS staff suggests that object locations may shift by as much as a foot. Users who require the best possible accuracy should obtain the original TIFF imagery. Assessment of the fitness for use of this service is entirely the responsibility of the user; see Distribution Liability for further information.

Attribute Value Accuracy Information:
Attribute Accuracy Report: The following is the Attribute Accuracy Report for the original imagery: The accuracy of the ground control and airborne GPS data is confirmed by the evaluation of the results of the analytical bundle adjustment. The residuals of the final adjustment ensured compliance with NSSDA standards. During the scanning of the original aerial film, the image histogram for each frame is carefully examined to ensure that the image has been scanned so that the minimum and maximum brightness values are captured to eliminate any loss of detail due to saturation of dark or light areas. The ortho-rectified images are checked for image quality and tone-balanced using a combination of techniques including adjusting the histogram of each color band in Intergraph's IRAS-C software, and using the block tone-matching algorithms provided by Orthovista software. Evaluation of the DEM includes checking the terrain data for spikes and wells, omissions, and other anomalies that do not meet the project accuracy requirements. Using the adjusted horizontal coordinates of the aerotriangulation points, their heights are interpolated from the neighboring DEM points. The interpolated coordinate of the aerotriangulation point is then compared with the actual adjusted Z value of the aerotriangulation result. Visual inspection of the stereoscopic model and contour lines is also made allowing the detection of errors in the DEM.

Process Description:
Softcopy aerotriangulation utilizes the GPS ground control and image coordinate measurements which are run through bundle block adjustment software computing the exterior orientation parameters for each image of the photogrammetric project. The original aerial film was scanned utilizing a Zeiss precision photogrammetric scanner at a resolution of 14.0 microns. Using these scans the aerotriangulation process employs a rigorous mathematical model which detects measurement errors, and corrects for systematic image distorion, film shrikage, atmospheric refraction and camera lens distortions. The final bundle adjustment results are inspected to ensure that the RMSE meets the required 1 part in 10000.

Process Step:
Process Description:
The procedure utilized for the development of the DTM/DEM development used a combination of automated and manual techniques. The initial phase produced an intermediate terrain data set using a series of automatic data processing algorithms known as Automatic Terrain Extraction. This data set is further refined using a series of automatic filtering techniques, along with visual inspection and editing processes to produce a fully compliant DEM meeting the project specifications. To enhance the results of the ATE process linear and polygonal break line information was collected in all areas where a more rigorous data set was required to define changing terrain conditions. This break line data is then merged into the correlated terrain file and used to influence the DTM by correcting areas where the ATE process has failed to depict the terrain accurately.

Process Step:
Process Description:
Digital orthorectification includes a spatial and radiometric transformation of the scanned image from line/sample space into the specified ground coordinate system. The interior and exterior orientation parameters from the aerotriangulation process are used to project each pixel into the ground coordinate system, while the DEM is used to correct for relief displacement. The CIR orthophotos are generated by Intergraph's Base Rectifier using a cubic convolution algorithm. Once the images are ortho-rectified, they are checked for geometric accuracy and image quality, and tone-balanced. The individual overlapping orthophotos are mosaicked together using Automatic Image Mosaicker (AIM) software into one seamless image data set. Final tiles are then extracted from the image set to the State of New Jersey's tiling scheme.

Ordering Instructions: This OGC-compliant WMS is compatible with a broad range of client software (See http://www.thecarbonproject.com/gaia.php for one example of a free client). Use part or all of the network resource address to connect to the service. There are multiple sub-layers in the WMS; turn all of them off except "Infrared 2002". ArcGIS-Specific Instructions: One-Time Setup (for each user profile) -Launch ArcCatalog -Highlight "GIS Servers" in the catalog tree and double-click "Add WMS Server". -In the URL field, type http://njwebmap.state.nj.us/njimagery -Click the "Get Layers" button to confirm you have the correct URL. -After the layer information appears, click the OK button. -"New Jersey on njwebmap.state.nj.us" will appear in the list of GIS servers. Using the service -In ArcGIS 9.3: In ArcCatalog, double-click the "New Jersey" entry that appears within the entry for the GIS server. Double-click the "Imagery" entry. Drag the sub-layer you wish to use into your ArcMap window. -In ArcGIS 9.2 or earlier: You cannot see the sub layers in ArcCatalog. Drag the "New Jersey" service name into ArcMap. Expand the "New Jersey" service name in ArcMap's table of contents. You should see several sub-layers. For faster performance and less load on our server, turn all of them off except for "Infrared 2002". -In all versions: If you already have other layers in the map, the web map service will be projected to match them. If not, it will default to longitude/latitude, and you should change the projection. Right-click on the layer name and choose "change coordinate system". NJ State Plane is recommended. -You may get a warning message about the coordinate transformation; dismiss it. The errors described in that warning will not actually occur if you are using NJ State Plane coordinates. That coordinate system is supported directly in the web map service, so ArcMap does not wind up doing the coordinate transformation. -Note: ArcGIS 9.3 allows you to preview the map service in ArcCatalog; earlier versions do not.
