Identification_Information: Citation: Citation_Information: Originator: Monterey Peninsula Water Management District Publication_Date: 2004 Title: 686102.tif Geospatial_Data_Presentation_Form: remote-sensing image Publication_Information: Publication_Place: Monterey, CA Publisher: MPWMD Online_Linkage: \\filegish2o\sdrive\Political_Boundaries\Ortho2003\Images\others\CalAm\686102.tif Description: Abstract: Orthophotos combine the image characteristics of a photograph with the geometric qualities of a map. The primary digital orthophoto is a 2-foot or 0.5-foot ground resolution, image cast on the California State Plane Projection on the North American Datum of 1983 (NAD83), zone 4. The geographic extent of the imagery is equivalent to a 2000 by 3000 foot rectangle. The normal orientation of data is by lines (rows) and samples (columns). Each line contains a series of pixels ordered from west to east with the order of the lines from north to south. For natural color imagery a digital number from 0 to 255 is asssigned to each pixel but that number refers to a color look-up table which contains the red, blue and green (RGB) values, each from 0 to 255, for that digital number. Areas where the rectification process is incomplete due to incomplete data (i.e., lack of elevation data, gaps), are represented with the numeric value of 0. The metadata provided in the digital orthophoto contain a wide range of descriptive information including format source information, production instrumentation and dates, and data to assist with displaying and georeferencing the image. The standard distribution format of the imagery will be JPEG compressed images on CD-ROM. Purpose: Digital 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: These digital orthophotos have been made available thru the Central Coast Joint Data Committee (URL http://www.ccjdc.org/). The data distributed by MPWMD have been reformatted into GeoJPEG format, with FGDC compliant metadata.

Security_Information: Security_Classification: Unclassified Native_Data_Set_Environment: Microsoft Windows 2000 Version 5.0 (Build 2195) Service Pack 4; ESRI ArcCatalog 9.1.0.722 Cross_Reference: Citation_Information: Originator: Monterey Peninsula Water Management District Publication_Date: 2003 Title: Digital Orthophoto, MPWMD Geospatial_Data_Presentation_Form: remote-sensing image Publication_Information: Publication_Place: Monterey, CA Publisher: Monterey Pensinsula Water Management District Data_Quality_Information: Attribute_Accuracy: Attribute_Accuracy_Report: During photographic reproduction of the source photography, limited analog dodging is performed to improve image quality. Analog dodging consists of holding back light from certain areas of the sensitized photographic material to avoid overexposure. The diapositive is inspected to insure clarity and radiometric uniformity. Diapositive image brightness values are collected with a minimum of image quality manipulation. Image brightness values may deviate from brightness values of the original imagery due to image value interpolation during the scanning and rectification processes. Radiometry is verified by visual inspection of the digital orthophoto quadrangle with the original unrectified image to determine if the digital orthophoto has the same or better image quality as the original unrectified input image. Slight systematic radiometric differences can be detected between adjacent imagery files due primarily to differences in source photography capture dates and sun angles of aerial photography along flight lines. These differences can be observed in an image's general lightness or darkness when compared to adjacent photo file coverages. Logical_Consistency_Report: No logical test were performed Completeness_Report: All orthoimagery is visually inspected for completenessto ensure that no gaps, or image misplacement exist in the 2000 by 300 ft image area or in overedge coverage. Images may be derived by mosaicking multiple images, in order to insure complete coverage. All images are cloud free within the image area. Source photography is leaf-on in deciduous vegetation regions. Void areas having a radiometric value of zero and appearing black may exist. These are areas for which no photographic source is available or result from image transformation from other planimetric systems to the California State Plane projection. In the latter case, the void sliver areas are on the outside edges of the overedge area. The data set field content of each image header record element is validated to assure completeness prior to archiving in the MPWMD server. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: The imagery 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 Sanborn , LTD proprietary software. The program determines the accuracy by finding the line and sample coordinates of the passpoints in the image and fitting these to their ground coordinates to develop a root mean square error (RMSE). Additional information on this testing procedure can be found in Monterey Peninsula Water Management District, 2004, Technical Memoranda 04-02: 2003 AMBAG Regional Orthoimagery Project, Final Report, Monterey, CA. Adjacent images, when displayed together in a common planimetric coordinate system, may exhibit slight positional discrepancies across common image boundaries. Linear features, such as streets, may not be continuous. These edge mismatches, however, still conform to positional horizontal accuracy within the NMAS. Field investigations to validate imagery positional accuracy reliabilty were completed by Monterey Peninsula Water Management district in 2003.
