Title: NOAA Seamless Raster Navigational Charts (RNC)
Short Name: seamless_RNC
Status: Completed
Publication Date: 2011
Abstract:

The NOAA Seamless Raster Chart Server provides a seamless collarless mosaic of the NOAA Raster Navigational Charts (RNC). The RNC are a collection of approximately 2,100 charts and inset maps at varying scales and resolutions. Full information on the NOAA RNCs can be found here: http://www.nauticalcharts.noaa.gov/mcd/Raster/. The Seamless Raster Chart Server integrates all charts in a single map service and clips the charts to the extent of the chart, removing the map collar. The set of charts displayed automatically change based on the viewer's scale to provide the most useful chart scale within the view. The charts in the Seamless Raster Chart Server are updated once every month at the beginning of the month to provide the latest Notice to Mariners updates.

Purpose:

This product provides an automatic view of charts within the user's view, automatically choosing appropriate charts and scale without having to download the individual charts from the NOAA Office of Coast Survey.

Notes:

1542

Supplemental Information:

Once per month, at the beginning of the month, a complete set of all charts and inset maps are processed. Charts are reprojected from their source projection to WGS84 Web Mercator (Auxiliary Sphere) using the GDAL projection libraries. The map collar information is clipped on-the-fly during display using chart boundaries and attributes defined in http://www.charts.noaa.gov/RNCs/RNCProdCat.xml. Chart display order and visibility are determined by through Esri algorithms that display the appropriate chart. Layering is determined by the area of the entire chart and charts with a smaller area are given display order precedence over charts with a larger area.

Data Quality

Horizontal Positional Accuracy:

The original raster navigational charts have been automatically projected from their original source projection to the WGS84 Web Mercator (Auxiliary Sphere) projection using GDAL projection libraries.

Vertical Positional Accuracy:

The vertical positional accuracy corresponds to the respective chart information as found at http://www.nauticalcharts.noaa.gov/mcd/Raster/

Completeness Report:

All raster navigational chart .KAP files produced by NOAA are include in the map service except for 62 table insets that do not have associated geographic referencing information.

Conceptual Consistency:

The information in the chart is accurate to the chart listed in the NTM_DATE attribute of the NOAA Raster Chart Footprints layer.
