NOAA Chart Display Map Service
type: Dataset
description: The NOAA Chart Display Service (NCDS) renders NOAA electronic navigational chart (NOAA ENC®) data with “traditional paper chart” symbology in online and offline applications for which a basemap of nautical chart data is desired, including GIS, web-based, and mobile mapping applications. The service uses symbols, labels, and color schemes familiar to those who have used NOAA paper nautical charts or the NOAA Custom Chart application. NCDS is available as Esri REST Map Service, OGC Web Map Service (WMS), and MBTiles formats. The ENC data in the service are updated weekly and include all of the latest Notice to Mariners corrections.
