Abstract: |
Oblique and nadir imagery was acquired following Hurricane Sally in September 2020. The aerial photography missions were conducted by the NOAA Remote Sensing Division. The images were acquired from an altitude of 2500 to 5000 feet, using a Trimble Digital Sensor System (DSS). |
Purpose: |
This imagery was acquired by the NOAA Remote Sensing Division to support NOAA national security and emergency response requirements. This aerial imagery will primarily support NOAA interests including safety of navigation, HAZMAT and marine debris impacts, as well as impacts to coastal zone management interests. It is not intended for mapping, charting or navigation. In addition, it will be used for ongoing research efforts for testing and developing standards for airborne digital imagery. |
Supplemental Information: |
The ground sample distance (GSD) for each pixel is 15 cm to 30 cm. In an effort to acquire imagery in a timely manner after the event, clouds may be present in the imagery. Be advised that the bounding coordinates reflect the extents of the images acquired for this event and do not imply full image coverage of the area. |

Data Quality
Horizontal Positional Accuracy: |
The accuracies have not been assessed. The absolute horizontal positions should be in the 3-5 meter range in areas with little or no topographic relief. |
---|---|
Quantitation Limits: |
The horizontal positional accuracy and the assurance of that accuracy are dependent upon the accuracy of the data inputs to the rectification process. |

Process Steps
Process Step 1
Description: |
Individual images were ortho-rectified from POS AV GPS-Aided Inertial Navigation Solution parameters using OSSIM software provided by Radiant Blue. Mosaic data have not been histogram stretched and only minimal color balancing has been performed. The images are in 8 bit RGB. The DEM source is the USGS NED. Original image tiles are 2.5 km by 2.5 km squares. |
