Title
NOAA Electronic Navigational Charts [Pennsylvania]
Description
Two ENC display services provide simple HTTP interfaces for user applications to request geo-registered nautical chart images from NOAA databases for display in online and offline applications for which a basemap of nautical chart data is desired, including GIS, web-based, and mobile mapping applications. The chart images are rendered from the latest NOAA electronic navigational chart (NOAA ENC®) data. The ENC data and the chart images derived from it are updated weekly. Each display service portrays the ENC data with a different symbology set. The ECDIS Display Service uses symbology developed by the International Hydrographic Organization (IHO) for the display of ENC data on Electronic Chart Display and Information Systems (ECDIS) that large ocean- going vessels and many smaller commercial ships use for navigation. This symbol set is commonly referred to by its IHO specification number, "S-52," or as "ECDIS symbology." The ENC Viewer portrays ENC data using this ECDIS symbology. ECDIS Display Service ECDIS Display Service rendering of ENC along the Columbia River with symbology specified by the IHO. https://www.nauticalcharts.noaa.gov/data/gis-data-and-services.html#enc-display-services
