Seamarks/INT-1 Cross Reference
INT-1 Cross reference
This page illustrates the renderings of the map features detailed in the IHO document INT-1 together with the tags necessary to invoke those renderings. As these illustrations are of particular examples of each class of feature, few of the many possible combinations of key/value pairs are shown. Full documentation of objects and their attributes.
The information presented below is derived from the IHO documents S-57 APPENDIX B.1 Annex D – INT1 to S-57/52, S-57 APPENDIX B.1 Annex A - Use of the Object Catalogue for ENC and the OpenECDIS document Encoding Guide for Inland ENCs. It provides a cross-reference between the symbols used in nautical charts, their OSM tags and the INT-1 reference numbers.
Superseding standard S-101 is presented in IHO Geospatial Information Registry.
