Description:

Abstract:

NOAA's Office of Coast Survey (OCS) is responsible for generating the 3 Nautical Mile Line, Territorial Sea, Contiguous Zone, and Exclusive Economic Zone (EEZ). 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 MLLW 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.

Digital maritime limits for Puerto Rico and the U.S. Virgin Islands are contained within a zipped file. Within the zipped file are several polyline shapefiles. Also included in the zipped file is an estimated 9 nautical mile Natural Resources Boundary for Puerto Rico. This limit was created at NOAA for the purposes of updating the nautical charts and may not be the same as the Submerged Lands Act limit created by the Minerals Management Service.

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.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:

The baseline points were derived from the largest scale charts and reprojected onto smaller scale boundary charts for boundary generation. In CARIS LOTS, the working mapping files were defined as the projection of the chart with a .01 meter X/Y resolution. 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. There is 1 to 1 correspondence between the Extracted Vector Shoreline and the paper nautical chart. In some instances, the Extracted Vector Shoreline did not provide full coverage; therefore, heads-up digitizing in the CARIS environment was necessary. The attributes established in LOTS were SourceDoc and Limit. The SourceDoc values reflect the nautical chart or hydrographic survey number upon which the baseline points were taken and are assumed to be accurate. The digital boundaries were projected in the same environment from the designated baseline. No added tests were conducted.

Logical_Consistency_Report:

The data, which reflects the largest scale nautical charts or hydrographic surveys of the area, are believed to be logically consistent.

Completeness_Report:

The maritime limits are complete for Puerto Rico and the U.S. Virgin Islands. The limits may be updated at a later date if the paper depiction of the farthest seaward low-water mark changes. This limits were created for internal purposes only to improve the accuracy of the charted maritime limits. These limits not designed for legal purposes. For a legal depiction of the limits, please see NOAA's paper nautical chart.

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. In cases such as the use of asterisk rocks (rocks awash), hydrographic surveys were referenced to determine if the features were drying at mean lower low water. 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 boundaries 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 or hydrographic surveys. No specific test was used to determine the vertical accuracy of the points.

The maritime limits are created from normal baseline points. Points representing the baseline are referenced from the farthest seaward low-water mark as depicted on the largest scale, paper nautical charts. NOAA used a raster depiction of the paper nautical chart via the Coastal Map rasterization process. These Coastal Maps (GeoTIFFs) were used as backdrops to the working CARIS map. Projections were set based on the projection of the nautical chart.

CARIS LOTS has a tool called the "Envelope of Arcs," which requires a vector low water line input in order to create the limits and determine contributing baseline points. Since there is a 1 to 1 relationship between the nautical chart and the extracted low water line, the Extracted Vector Shoreline product was used as input to the "Envelope of Arcs" tool to make the job of designating baseline points and determining the boundary more efficient. In some instances, not enough information was provided with the Extracted Vector Shoreline; therefore, some low water lines were delineated through heads-up digitizing in the CARIS environment.

Process_Step:

Process_Description:

For each chart extent, a separate mapping file was created in LOTS. The projection parameters for each mapping file were defined to be the same as each chart. The x/y resolution of the mapping files were set to .01 nautical miles. In some instances, new topographic data and/or projection parameters were applied to these charts prior to publication; therefore, internally created Coastal Maps were used as raster nautical chart backdrops. The changes in topography or projection parameters will be published in the next edition of the nautical chart.

Process_Step:

Process_Description:

The appropriate Extracted Vector Shoreline shapefiles were added to each CARIS mapping file. The x/y resolution for each mapping file was set to .01 nautical miles, and there was a mapping file for every chart extent. After loading the vector shoreline shapefile into the mapping file, some cleaning was performed to ensure that only the seaward-most low water mark was represented in the mapping file.

Process_Date: 200308 through 200312

Source_Produced_Citation_Abbreviation: CLEANSHORE

Process_Step:

Process_Description:

In the LOTS environment, the "Envelope of Arcs from Normal Points" tool was applied to each cleaned low water line(s) and any additional points from hydrographic surveys. The calculations were performed on each island of Puerto Rico and the U.S. Virgin Islands against the vector low water line representing the largest scale nautical chart of the area of focus. As input to the "Envelope of Arcs" tool, OCS selected the boundary 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 boundary distance and choosing the seaward-most points along the low water line.
