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 text file as a series of points with .1 nautical mile spacing.

Digital boundaries of the Three Nautical Mile Line, Territorial Sea, and Contiguous Zone for the Hawaiian Islands are contained within a zipped file. Within the zipped file are shapefiles. The shapefiles are polylines which were created by connecting the points exported from the LOTS environment.

Purpose:
This dataset is to be used as the source for the depiction of maritime boundaries on NOAA's paper nautical chart and electronic navigational chart. The maritime boundaries 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 boundaries.

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:
These boundaries are complete for the Hawaiian Islands. They may be updated at a later date if the paper depiction of the farthest seaward low-water mark within the area changes. These boundaries were created for internal purposes only to improve the accuracy of the maritime boundaries that are applied to the paper nautical chart. These boundaries are not designed for legal purposes. For a legal depiction of the boundaries, 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.
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 boundaries 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 boundaries 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 in the Hawaiian Islands. The x/y resolution of the mapping files were set to .01 nautical miles. Because new topographic data and projection parameters were applied to each of these charts prior to publication, internally created Coastal Maps were used as raster nautical chart backdrops.
Source_Used_Citation_Abbreviation: COASTMAP
Process_Date: 200303 through 200309
Source_Produced_Citation_Abbreviation: PROJMAP
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.
Source_Used_Citation_Abbreviation: VECSHORE
Process_Date: 200303 through 200309
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 the hydrographic survey. The calculations were performed on each island of the Hawaiian Islands in each mapping file 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. As part of the tool, the contributing baseline points were written to a text file as decimal degrees with 10 point precision.

The resulting boundaries were attributed in CARIS and exported using the "Output as a Text File" tool. The line was exported as a series of points .1 nautical miles apart in decimal degrees. This point file was parsed to be tab delimited, brought into ArcView 3.2, and converted to a shapefile. The point shapefile was converted to a polyline using the XTools extension.
