Traditionally, these maritime limits have been generated by hand from the low water line depicted on paper, U.S. nautical charts. Upon final approval by the U.S. Baseline Committee, these legally-binding maritime limits are applied to the next edition of nautical charts produced by the Marine Chart Division of OCS. Due to new cartographic production processes and the availability of digital products such as Electronic Navigational Charts (ENCs), the Coast Survey Development Laboratory (CSDL) is supporting OCS' Chief Geographer in developing improved techniques for generating more accurate, digital maritime boundaries. Through the use of Geographic Information Systems (GIS) software such as CARIS' LOTS and ESRI's ArcGIS, CSDL will provide NOAA cartographers and the public with the latest vector representations of these boundaries. In our effort to create digital boundaries, we are utilizing CSDL's Extracted Vector Shoreline from the largest scale nautical charts. This low water line is used as input to CARIS' LOTS: Limits and Boundaries software for the designation of a baseline. Once the boundaries are created, they are exported to a shapefile file using CARIS' Import SHP utility. These polyline shapefiles are contained within a zipped file. Purpose: This dataset is to be used as the source for the depiction of maritime limits on NOAA's paper nautical chart and electronic navigational chart. The maritime limits were constructed from baseline points that represent the most seaward, drying features at mean lower low water on NOAA's largest scale, latest edition, paper nautical charts of the area. These digital boundaries do NOT represent the legal depiction of the maritime limits.

The map projections were set to Mercator with a 0.001 meter X/Y resolution. The scaling latitude used for the CARIS maps were determined by finding the midpoints between the northeast and southwest bounding coordinates of each project area. The baseline points were derived from the largest scale charts. As NOAA's raster nautical charts were brought into the CARIS environment, the CARIS map was reprojected on the fly to match the chart's projection. To aid in the baseline point designation process, NOAA utilized the Extracted Vector Shoreline product. This product contains the vector low water line extracted from source binary raster files which are compiled to create the paper nautical chart. The Extracted Vector Shoreline was adjusted to achieve a 1 to 1 correspondence between it and the raster nautical chart. In some instances, the Extracted Vector Shoreline did not provide full coverage; therefore, heads-up digitizing in the CARIS environment was necessary. Once the baseline was determined, limit lines were projected through a method called envelope of arcs. Each limit line was attributed after export from LOTS to shpfile format. The attributes are Limit, Location, State, Approved Date, Source Scale Range, Begining Chart Year, Ending Chart Year, and Chart Datum. No added tests were conducted. Logical_Consistency_Report: The data, which reflects the largest scale nautical charts of the area, are believed to be logically consistent. Completeness_Report: The maritime limits are complete for Oregon and Washington. The limits may be updated at a later date if the charted depiction of the farthest seaward low-water mark changes. These limits were created for internal purposes only to improve the accuracy of the charted maritime limits. These limits are not designed for legal purposes. For a legal depiction of the limits, please see NOAA's paper or raster nautical charts. Positional_Accuracy: Horizontal_Positional_Accuracy: Horizontal_Positional_Accuracy_Report: No specific test was performed on the dataset. The data is a reflection of the largest scale raster nautical charts of the area. The number of decimal places used in the output format does not imply an accuracy level higher than the source chart documents. Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: The maritime limits are projected from a designated baseline. Points representing the baseline are referenced from the farthest seaward low-water mark as depicted on the largest scale, raster nautical charts. No specific test was used to determine the vertical accuracy of the points.

NOAA's Extracted Vector Shoreline (EVS) was used when available to make the job of boundary delimitation more efficient. The EVS' mean lower low water and mean high water lines were merged using Safe's Feature Manipulation Engine (FME) to a single low water line. Modification of the EVS occurred in the CARIS environment to achieve a 1 to 1 relationship between the raster nautical chart and the extracted low water line. In some cases, either not enough information was provided in the EVS or there was no EVS available for a particular chart. In these cases, the low water line was delineated through heads-up digitizing in the CARIS environment. The resulting vector low water line was used as input to the "Envelope of Arcs" tool. This vector low water line corresponds to the latest edition raster nautical chart as referenced in the citation information section above. The dates of these latest editions were current as of 2005.

Process_Step: Process_Description: The latest edition, largest scale charts and associated vector low water lines were used to create a continuous vector low water line from which baseline points would be chosen. In the LOTS environment, the "Envelope of Arcs from Normal Points" tool was applied to the cleaned low water line. As input to the "Envelope of Arcs" tool, OCS selected the limit distance in nautical miles and designated the attributes for the baseline points. This tool generated the contributing baseline points and the boundary limit using a wagon-wheel filtering process of rolling a circle with a diameter specified by the limit distance and choosing the seaward-most points along the low water line.
