From December 1990 through February 1991, the USGS and IOS (Institute of Oceanographic Sciences, U.K.) scientists conducted three surveys within the Johnston Atoll U.S. EEZ surrounding Johnston Island. The results of these surveys were 16 digital mosaics of a 2 degree by 2 degree area with a 50-meter pixel resolution. Purpose: This remote sensing image of the ocean seafloor is 14 of 16 mosaics created from the Johnston Island EEZ GLORIA sidescan-sonar data.

Logical_Consistency_Report: not applicable Completeness_Report: All available imagery were used to create this mosaic. Data were acquired during four cruises using the 6.5 kHz GLORIA sidescan-sonar system and a 45-km total swath width. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Primary navigational control for this survey was by Loran-C supplemented by satellite navigation. Accuracy of location of the navigation fixes is estimated to be better than 100 meters. The positional accuracy of features in the image mosaics was affected by the digital production of the mosaics. However, we believe that the accuracy of the technique is within the accuracy of the navigation data.

Each completed pass contained a maximum 720 "lines" of data at the usual 30-second pulse repetition rate. Each line consisted of a 1024 byte record that contained the port and starboard returns from a single ping as well as header information. These "passes" contained geometric and radiometric distortions which had to be corrected before they could be digitally mosaicked. Process_Step: Process_Description: The GLORIA "passes" necessary to complete the mosaic were retrieved from magnetic tape. Navigation data were merged into the individual "passes" to update the header information with depth and location coordinates.

Slant-range error is mislocation of pixels in the cross-track direction compared to their proper location on a map. This error occurs due to the way that the sidescan-sonar senses distance to a target. After the slant-range correction has been made, the across-track location of targets is accurate.

The noise was removed by applying two separate boxcar filters: (1) a high-pass filter that will contain the high-frequency component of the image without the noise; and (2) a low-pass filter that will include the low-frequency component of the image without the noise.

The aspect-ratio distortion was removed by using the navigation data to compute the distance traveled by the ship. Given the distance traveled, the number of pixels (each representing 50 m) required along the particular segment was calculated. The original pixels were then duplicated the appropriate number of times to fill the space with 50-meter pixels and thus achieve a 1:1 ratio between along-track and across-track distances. The practice of duplication to create a square 50-meter pixel size was followed so that information in the across-track direction would not have to be omitted.

Because the delta velocity correction typically stretches the imagery 1:2.5 times, a 2 by 2 low-pass filter is applied to the image to smooth and reduce the blockiness that results from the line duplication. The 2 by 2 low-pass filter smoothes out the blockiness introduced into the image without over smoothing and blurring the image.

This enhancement involved creating two separate images from the input image. The images were produced as a result of 151-line by 31- sample high-pass filter plus a 151-line by 401-sample low-pass filter. The two resultant images were then digitally combined to produce an image similar to the original but without the halo effect.

Interactively, a line was drawn on a video display outlining the portion of each image segment to be retained while comparing it to adjacent segments. Then all pixels outside the area enclosed by the line were converted to zero values, thereby retaining only that portion of the image desired. Finally, each stenciled segment was mosaicked to adjacent segments, sequentially building the composite map. In this way a digital file was created with the desired map projection for each imagery sheet (mosaic).
