A worldwide nautical charts catalog

with both raster & vector charts material coming from international Hydrographic Offices

  1. Raster nautical charts (RNCs) : with bitmap copies of the official navigational paper maps
  2. Vector nautical charts (ENCs) : with vector ENCs (s-57 & s-63 formats) rasterized using s-52 rendering

1. Raster charts catalog

the basic service

with an exhaustive catalog of raster charts from the following international Hydrographic Offices

These digital georeferenced raster nautical charts (more than 9000 charts), 

with material coming directly from the full catalogue  of official International Hydrographic Offices,

are  regularly and automatically updated through our Cloud computing solution.

Raster charts coverage

according to the different international Hydrographic Offices' sources

click on the 'Visible layers' popup menu to select the layer(s)
click on any point of the world map to get the specifications of the corresponding nautical raster chart (title, scale..)
Note : the viewer doesn't display the raster contents of the charts but only the geographical coverage.

2. Region coverage with ENC vector charts

A complementary offer for local areas

The   GeoGarage  platform also serves images of vector   ENC  Electronic navigational charts as a complementary offer to the different raster nautical charts (RNC) layers for its B2B customers  ( see  GeoGarage blog article).

'A la carte' service procedure : with ENCs, the user can select a limited set of charts for a chosen region in the worldwide catalog according six scale bands available :

  • 1 : Overview scale band consists of ENC files with a scale band smaller than 1:1,500,000. 
  • 2 : General : from 1:600,001 to 1:1,500,000. 
  • 3 : Coastal : from 1:150,001 to 1:600,000. 
  • 4 : Approach : from 1:50,001 to 1:150,000. 
  • 5 : Harbour : from 1:5,000 to 1:50,000. 
  • 6 : Berthing : larger than 1:5,000. 
Note :  The ENC filename is stored in the attribute named DSNM from the “coverage_area” feature layer.  The third character within the filename is a numeric value referencing to the following scale band category.  For example, a filename of US2EC02M.000 indicates that it is within the General scale band category.


So this implementation of ENCs (worldwide catalogue of about 14,000 charts) allows to complete the catalog of available nautical charts (more than 9,000 raster charts) usually proposed by the GeoGarage platform, for regions where the GeoGarage can't access -for the moment- to raster data (pending licenses with  some international Hydrographic Offices ) for webmapping applications. The following countries are concerned : China (C1), Croatia (HR), Estonia (EE), Finland (FI), Georgia (GE), Indonesia (ID), Latvia (LV), Montenegro (ME), Poland (PL), Spain (SP), Sweden (SE), Ukraine (UA).
