Abstract:
This image tile is part of an orthophotography project covering mostly contiguous areas of interest in and adjacent to the jurisdictional boundary of the Mid Region Council of Governments (MRCOG) in central New Mexico. The project is known as the 2012 Digital Orthophotography project. The project was begun and completed in 2012. The overlapped tiles of orthophotography are images which depict color digital aerial photographs acquired in March of 2012 during leaf-off conditions and in May of 2012 over the mountainous areas to minimize snow cover. Lens and terrain distortion have been removed and tonal differences between adjacent images have been minimized to form a mosaic of the entire project area. The project area includes the Albuquerque Metropolitan area and both Western Plains, Central Mountains, and Rio Grande River Valley adjacent to the metro area. Orthorectified imagery is assumed to depict features at ground level, so above ground features may show some distortion from elevation. The only exceptions to this are bridges and elevated roads, which have been checked for distortion and true orthorectified when distortion was encountered. Each orthorectified pixel is exactly one half foot square throughout the project areas. Quality and accuracy of this orthophotography was evaluated with control independent from the photogrammetric solutions. The image products conform to American Society for Photogrammetry and Remote Sensing (ASPRS) Class I Standards for 1"=100' horizontal mapping. Project coordinate systems were based off the New Mexico State Plane Central Zone projection with the horizontal datum North American Datum 1983 (1992)/HARN and vertical datum North American Vertical Datum 1988 and units of US Survey Feet. Transformed projections and datums available in this project include Universal Transverse Mercator Zone 13 NAD83 (1992)/HARN, Meters.
Purpose:
The orthophotography is useful as a layer in a Geographic Information System (GIS) or in CAD environments and is intended to aid in planning, digital map revision, position representation, and spatial analysis. It is not intended to furnish measurements accurate enough for engineering design work.

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 (elevation data, aerotriangulation control and methods, camera calibration, and source imagery parameters). These parameters are reviewed post orthorectification against the output imagery and initially validate the product is in compliance with ASPRS standards. Additionally, NSDI Part 3 Chapter 3 - (<http://www.fgdc.gov/standards/projects/FGDC-standards-projects/accuracy/part3/chapter3>) outlines process for determining horizontal RMSE and 95% confidence level for accuracy. Data deemed useful for this validation include independent higher accuracy geodetic control, GPS ground surveys, photogrammetric methods, and databases of high accuracy point coordinates. Check point locations are generally distributed more densely in the vicinity of important features and more sparsely in areas that are of little or no interest. This data set has uniform positional accuracy thus the points are spaced so 20% of the check points are located in each quadrant of the dataset. Tested 1.19 feet horizontal accuracy at 95% confidence level. One hundred thirteen (113) checkpoints yeild a final RMSE of 0.69.

Horizontal_Positional_Accuracy_Explanation:

Source_Contribution:
Existing elevation data from three sources was used as input to provide ground elevations for the orthorectification process. Primary source of elevation data comes from a LiDAR aerial survey conducted with the 2010 Digital Orthophotography and Elevation Data project. The other sources for DEM were existing elevation models built from previous LiDAR projects and autocorrelation techniques. The DEM data (elevation data) is suitable for most terrain analysis applications with the exception of engineering design.
Process_Step:
Process_Description:
Aerial Triangulation - Images were aerotriangulated to finalize their external orientation. Intergraph ISAT and GeoMedia Pro were used to perform digital point matching/mensuration/block adjustments and quality control queries respectively. Final block adjustments were evaluated at sub pixel accuracy.

Process_Step:
Process_Description:
Orthorectification - Images were orthorectified to remove distortions caused by changes in the elevation of the terrain. The orthorectification process used a cubic convolution interpolation method and a ground elevation sampling interval of sixteen pixels. Intergraph Imagestation OrthoPro was the software used for the orthorectification.

Process_Step:
Process_Description:
Orthomosaic - Images were color balanced and color corrected individually to ensure color consistency between flight lines, times of day, and dates of capture. Images were mosaiced into large aggregate tiles and automatic seamlines were used to combine the most nadir components of individual images. Aggregate tiles were again tonally balanced and color corrected with the entire project in view. A second global color adjustment was performed to minimize color changes across images. Project deliverable tiles were cut from the mosaic and formatted for delivery. Trimble OrthoVist was the software used to perform these steps.
