  Description:
    Abstract:
      The Louisiana State Legislature created the Coastal Wetlands Planning, Protection and Restoration Act (CWPPRA) in order to conserve, restore, create, and enhance Louisiana's coastal wetlands. The restoration plans developed persuant to these acts specifically require an evaluation of the effectiveness of each coastal wetland restoration project in achieving long-term solutions to arresting coastal wetland loss. This data set consists of digital data describing the photomosaic data for the Four Mile Canal Terracing and Sediment Trapping for the year 2010. Color-infrared aerial photography is acquired and scanned on a photogrammetric scanner that produces a high-resolution image in Tagged Image File Format (TIFF). Each frame is then orthorectified and mosaicked to produce a seamless image.
    Purpose:
      The intended use of this data set is to provide information to aid efforts in the conservation, restoration, creation, and enhancement of Louisiana's coastal wetlands. The photomosaic data is used for time comparisons to measure the rate of success for the CWPPRA's TV-18.

Data_Quality_Information:
  Attribute_Accuracy:
    Attribute_Accuracy_Report: Not applicable; data were not classified.
  Logical_Consistency_Report:
    All photography is reviewed for complete coverage, tone, and quality. Once the photography is accepted, it is then rectified and mosaicked to provide a seamless image of the area. All rectification meets or exceeds the horizontal National Mapping Accuracy Standards for a given scale.
  Completeness_Report: Data are complete as possible.
  Positional_Accuracy:
    Horizontal_Positional_Accuracy:
      Horizontal_Positional_Accuracy_Report:
        The accuracy of the horizontal positions is based on the accuracy of the georeferenced data source (which can be USGS DOQQs, DEMS, flight line center points, and/or calibration reports). The sources used vary from project to project. All USGS Mapping products adhere to the National Mapping Accuracy Standard.

    Process_Step:
      Process_Description:
        Photo Acquistion: Analog aerial photographs are acquired by using the Zeiss RMK camera ( Carl Zeiss AG, Oberkochen, Germany) at various scales depending on the project size, as follows: 1:6,000 (200 acres or less) , 1:12,000 (200 to 20,000 acres) , and 1:24,000 (over 20,000 acres). High resolution photography is acquired during late fall (prior to senescense) in order to obtain peak biomass for emergent marsh. Vertical photographs, free of clouds, smoke, and haze are taken between 10:00 a.m. and 3:00 p.m. to minimize shadowing. The sun angle must not be less than 45 degrees. Photographic images of marsh vegetation and open water are acquired by using a stabilized camera mounted on the aircraft. The scale of the photography is held as close as possible to the required scales for all photos. A 60 percent end lap and 20 percent side lap are required for the photography, which allows the photointerpreter to map the images in stereo.

    Process_Step:
      Process_Description:
        Imagery Processesing: The mosaicking and orthorectification of aerial photography is outsourced to a subcontractor who uses proprietary software to provide scientists of USGS NWRC with orthorectified deliverables. All Rectification meets or exceeds horizontal National Mapping Accuracy Standards for a given scale. The mensuration procedure is part of the rectification process and is performed in two separate phases. The first phase is to transfer control points from a Digital Orthophoto Quarter Quadrangle (DOQQ) to the new imagery. The X and Y coordinates for the image are determined by using the DOQQ, and the Z coordinate is determined by using a Digital Elevation Model (DEM). A sufficient number of points (usually 10-20) are transferred to align perimeter images and some interior images. The second phase is to transfer common points between adjacent photographs, both in-line and cross-strip. Typically, nine points are transferred bewteen photos. Initial estimates of the groud coordinates and estimates of the elevation of these points are determined by the DEM. Once the control and pass points are measured, an aerotriangulation (AT) is performed by using the measurement data and the initial estimates of ground point coordinates, aircraft position, and orientation. The results of the aerotriangulation are examined, the outliers are eliminated, additional points are added (if necessary), and the AT is repeated until a satisfactory result is achieved. The images are then orthorectified and mosaicked.
