Description:
Abstract:
This document describes a shoreline vector file that was produced by the University of Texas at Austin Bureau of Economic Geology (Austin, TX). This file contains the mapped 1995 Baffin Bay, Texas Gulf of Mexico coast. Funding for this project was provided by the Texas General Land Office. The shoreline was created by digitizing a line interpreted from a series of georectified 1995 digital orthophoto quarter quads (DOQQ). DOQQs are orthorectified false-color infrared images. They are projected in Universal Transverse Mercator (UTM) in meters on the North American Datum of 1983 (NAD83).
Purpose:
The shoreline file described in this document was created to be used in shoreline change analyses.

This file contains the shoreline of the entire Baffin Bay, mapped at a scale of 1:5000
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
This shoreline was interpreted from USGS Digital Orthophoto Quads (DOQs):The DOQ horizontal positional accuracy and the assurance of that accuracy depend, in part, on the accuracy of the data inputs to the rectification process. These inputs consist of the digital elevation model (DEM), aerotriangulation control and methods, the photo source camera calibration, scanner calibration, and aerial photographs that meet National Aerial Photography Program (NAPP) standards. The vertical accuracy of all DEMs are equivalent to or better than a Level 1 or 2 DEM, with a root mean square error (RMSE) of no greater than 7.0 meters. Field control is acquired by third order class 1 or better survey methods sufficiently spaced to meet National Map Accuracy Standards (NMAS) for 1:12,000-scale products. Aerial cameras have current certification from the USGS, National Mapping Division, Optical Science Laboratory. Test calibration scans are performed on all source photography scanners. Adjacent DOQs, when displayed together in a common planimetric coordinate system, may exhibit slight positional discrepancies across common DOQ boundaries. Linear features, such as streets, may not be continuous. These edge mismatches, however, still conform to positional horizontal accuracy within the NMAS. The Horizontal_Positional_Accuracy Value (see below) is an root mean square error (RMSE) of image positions to ground coordinates as determined by the orthorectification software used.

Process_Description:
The shoreline was interpreted as the contact between wet and dry sand. Lines were digitized from the DOQs at a scale of 1:5,000. United States Geological Survey DOQs are differentially corrected photographs flown in 1995 and 1996 at a scale of 1:40,000. They are 24 bit, 1 meter resolution TIFF World files projected in UTM zone 14, datum NAD83.
