58883 Data Set Published / External 47842 Imagery Project Completed 2020-02-20 This orthophotography dataset was created for the City of Eureka, California as a seamless 1.5-inch pixel resolution orthorectified aerial imagery dataset covering approximately 105 square miles of the city and its environs. The origin imagery was collected on July 24th, 2019 as a 36-bit RGB+NIR spectrum acquisition using an UltraCam digital camera system. Associated ground control was captured by a California Certified PLS and a recent LiDAR digital elevation model was utilized for vertical reference. All data was acquired and processed in California Zone 1 State Plane, NAD83(2011), NAVD88 in US Survey Feet. Deliverables included 4-BAND (RGB+NIR) TIFF tiles, JP2 1:25 compressed tiles and JP2 1:25 compressed mosaic. This dataset was created as a geospatial visualization and planning tool for the City of Eureka, California. This dataset was created for the City of Eureka by Access Geographic, LLC, Tempe, Arizona.

ArcGIS 10.1; Microsoft Windows 7; Microsoft Office; Intergraph's suite of photogrammetric products including Z/I Inflight and GeoMedia OrthoPro Accuracy of both airborne GPS and surveyed ground control are evaluated through the bundle adjustment. Digital acquisition frames are visually assessed for any abnormalities in color and quality. A 'blunder detection' phase is utilized during the AT process to ensure comprehensive tolerance. Quality control for the surface model includes a comprehensive quantitative analysis, a independent spot assessment, and a final qualitative analysis in completed with a visual review. The referenced source imagery utilized an original digital surface model derived LiDAR supported by surveyed ground control and airborne GPS and IMU data. Quality Control procedures included manual assessments of automated results and visual association during the production process. The AT adjustment process positively identifies any point that is out of tolerance with other values in the block. Out of tolerance points are promptly identified due to a survey error, a point coding error or a measurement error. These errors are detected during the preliminary adjustments and corrected for the final adjustment. 1 UltraCam acquisition frames were processed as Level 3 images using Vexcel UltraMap Software. Surveyed ground control and ABGPS control support the Aerial Triangulation process using Intergraph ISAT and Z/I software. An original surface model was generated. The digital orthorectified imagery was then generated based on this methodology and mosiacked as a seamless imagery coverage. 2019-01-01T00:00:00 gov.noaa.nmfs.inport:58883 Erik Hund 2020-02-20T09:19:02 Brianna Key 2024-02-05T17:15:41 2024-02-05 Office for Coastal Management OCM 1002 Public No No 2020-02-20 1 Year 2021-02-20
