INT 1 is a part of IHO standard S-4 (also including INT 2 and INT 3), mainly covering the symbols used in international navigational charts, whether paper charts or electronic. It is basically just a catalog of symbols matched with meanings and rendering descriptions.

In this document, only the numerical cataloged symbols are prioritized. INT 1 is divided into chapters given a capital letter (between A and U), with each symbols given a number. Leaps in numbers might mean grouping of symbols, or might indicate that symbols have been deleted. Subnumbered items are a form of grouping related symbols. Symbols with a lower case letter are not international agreed, most of these are national specifics, though some are nationally suggestions for rendering on international charts. For example, France have suggested symbol Df (not included in the list) for horizontal clearances under structures such as bridges. This symbol might be found on French produced international navigational charts, while English, German or Norwegian charts might use a different symbol, or choose not to render this information at all.

There are various other IHO standards, and also discussed on OSM have been S-57. This is a data exchange format, and raw ENC (Electronic Navigational Charts) data is often in this format, though the way it is stored on various ECDIS (Electronic Chart Display and Information System) software stores it in different ways. IMO definitions of ECDIS is documented in IMO Resolution A.817(19). IMO:Electronic Charts

Some times an electronic nautical chart might use the term ARCS, this is a raster chart, in other words a scanned paper chart calibrated to give as accurate position feed back as the ENC charts does, though the lack of layered data makes searching and selecting detail level completely different.

Both ENC and ARCS uses INT-1 symbols as well, so knowledge of INT 1 is useful for all types of nautical charts.

Nautical charts are available in two systems, Metric Charts and Fathom Charts. Various issuing authorities have different ways of indentifying the different. British Admirality who prints and issues nautical charts in the United Kingdom uses a yellow colour on land for Metric and a gray colour for Fathom. Det Norske Sjøkartverket who prints and issues the same charts in Norway uses the same yellow colour on Metric maps, but a green colour on Fathom maps.

In general, symbols are the same wether the chart is Metric or Fathom, and share many other characteristics as well. Distances in the charts are always available in Nautical Miles, though a scale with metric or imperal units might also be present depending if the chart is Metric or Fathom.

Charts covering United States are mainly Fathom, while (atleast when issued by Admirality) the rest of the world mainly are Metric.

S-57 is basically the data model of which electronic chart information is stored, and can be loosely compared to our tags. A clear documentation of how our tags can be converted to S-57 and visa versa is necessary to convert OSM maps to already used ENC formats, but this have little to do with how the information is presented on the display.

12: Seals of issuer (national chart agency) and International Hydrographic Organization (IHO) to show that chart is an international one. Purely national charts mighthave only national seal. Reprints of charts from other national series must also hold seal of origin (third seal)

13: Scale of chart at stated latitude. The scale is precisely as stated only at the latitude quoted

14: Linear scale on large-scale charts

15: Linear border scale on large scale coastal charts. On smaller scales use latitude borders for sea miles.

16: Cautionary notes (if any). Information on particular features. to be read before using chart

17: Source Diagram (if any). The source diagram should be studied before using the chart in order to assess the reliability of the sources. Navigators should be cautious where surveys are inadequate.

18: Reference to a larger scale chart

19: References to an adjoining chart of similar scale

20: Instruction to refer to complimentary nautical publications

Note: a and b are references used only in some national series. In the example (french) a refers to the French Notices to Mariners weekly, and b to identificator of a latticed chart.

Epave urgence.png

is under consideration by IALA to be implemented, but currently under testing (thus no INT-1 code).
Its purpose is to mark temporary dangers to navigation, such as new ship wrecks in high density traffic areas. The need of a special mark like this was highlighted after the Tricolor accident in English channel, where even if marked with not less than 5 Cardinal buoys, and guarded by a dedicated guard vessel, no less than 3 other ships collided with the semi-submersed wreck.

Color map

The colors in the table is advisory. The INT-1 convention doesn't really instruct in use of any specific color. As an example, the magenta used in Singaporian maps are closer to slate blue. I have focused here on finding names/defined colors as close to the most commonly used colors. The most important is the readability of the map. These colors reffers also to paper charts, ECDIS displays might deviate from this, specially when placed in any other modes than Day Display.

About the values in the table:

  • The HEX column represent the hex triplet of the color, most modern graphic editing software and style sheets can interpret these values directly.
  • The RGB values are entered in this form: rgb(red,green,blue). I am on purpose not using rgba(red,green,blue,alpha) as all colors in this style should be considered solid, though some symbols, the creater of the style sheets might decide upon different alpha value (semi-transparent). Values in the range 0-255.
  • The RGB% is the same as RGB, though the values are given in por cent. A value of 0 will give 0%, while a value of 255 will give 100%.
  • The MapCSS column is the RGB% value written as decimal number. This is the way preferred by the developers of MapCSS, specially as it allows for adding alpha value in the same argument.
  • The HSL column shows the color as Hue,Saturation,Light values. Some graphic editing software allows you to enter these values directly, and give you a different approach to altering the color. It is much easier with this approach to lighten or darken a color without altering the tint. HSL is supported from CSS3, but to my knowledge still not in MapCSS.
  • The W3C column is the name coresponding to the color as used in web CSS and HTML, and not directly ment neither for MapCSS nor SVG creation
  • The X11/SVG column is the name coresponding to the color as used by X11 and SVG. This is the names recognized by graphic software, as well as used by SVG, and therefor can be used in scripting of SVG files if bulk change of color is desired
  • The Comments column have comments explaining any differences in names, or containing the background color derived from scans of printed documents with various types of seamarks.
