Supplemental_Information: From 1995 to 1999 the United States Geological Survey conducted a multifaceted scientific study of the seafloor geology and geologic processes within the Monterey Bay National Marine Sanctuary. Included in this study and presented here is a digital photographic survey documenting the coastal morphology and stratigraphy between Point Aņo Nuevo and Santa Cruz, California, with precision-navigated overlapping images. Another part of the study is producing a digital database of seafloor geologic maps. A comparison of the newly acquired seafloor maps and coastline images provides a means of visualizing the transition from sea to land. The more than 500 digital coastline images included on this CD-ROM are linked by interactive location maps. The HTML and image files are also accessible by standard browser and image software. Locations were transcribed from global positioning system (GPS) data captured with each image. Where such data were missing or erroneous, an estimate (flagged in attribute table) was supplied. Arcinfo point coverage and attribute table were generated from the data.

The hierarchy of links looks like this: >Regional map (92 kb) > Detailed map (window x) > 72 dpi image > 300 dpi image The regional map displays the 23 areas into which the photographic images were divided. Each number on the regional map is a link to a detailed map (for example, window 8) that includes a sequence of about 30 images with an overlap of 5 images, for example, windows 8 and 9 have 5 images in common. Each of the points on a detailed map is linked to a 72 dpi version of the image captured at that location. Along with each 72 dpi image another link will display the higher-resolution 300 dpi image.

Logical_Consistency_Report: Point features present. The sea-level images of the coast were collected from aboard the research vessel RV David Johnston in November 1998. We started from Aņo Nuevo and motored southward to Santa Cruz at approximately 16 knots (30 km/hr) and acquired more than 500 overlapping, high-resolution digital images. Completeness_Report: Because of the rapid camera firing rates needed to acquire overlapping images, the GPS information would sometimes be missing, duplicated or erroneous because of inadequate satellite download time. In those situations, an interpolated position is inserted in the sequence log (photolog.txt). Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: Each photograph encompasses approximately 200 m of coastline-- varying with distance from shore--and overlaps between adjacent photographs are tens of meters. The photographs were taken with a 35-mm high-resolution digital camera connected to a portable global positioning system (GPS) receiver with a horizontal accuracy of less than 3 meters. For most of the images, GPS data (date, time of day, latitude, longitude, and altitude) are recorded in the upper left corner of each image. The GPS data are of the ship positions only and are best read on the higher-resolution (300 dpi) images. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: As all images were taken at sea level, the altitude data on each image should be ignored.

Each image, when uncompressed with Kodak software, has a file size of 4.5 Mb (megabytes). To fit all the images on one CD-ROM, each TIFF file was desampled and converted to a high-quality JPEG (xxx.jpg) image that is just under 1 Mb in size (300 dots per inch at 3 x 5 inch). A second set of images was desampled to about 30 to 50 kb (72 dots per inch at 4 x 5 inch) for more rapid viewing.
