International Chart Committee
Chairman: Commander C.G. DEM-EHO, Raul Martinez Sanchez (Mexico)
The idea of a common, worldwide chart series (INT Charts) produced to a single set of agreed specifications was adopted in 1971 by the International Hydrographic Organization (IHO). Under this arrangement, Member States wishing to print their own versions of another Members' INT charts, may do so by obtaining (by mutual agreement), copies of the necessary reproducible material and printing their own copies.
The IHO programme for small scale (1/10 000 000 and 1/3 500 000) INT charts, has been completed and many of the charts at medium and larger scales are in the developmental stages. The MesoAmerican-Caribbean Sea Hydrographic Commission is responsible for the area designated as Zone B on the map at the left. One task at hand is to complete the identification of countries who have agreed to produce or distribute charts. Some charts still need sponsors.
The following additional information is available:
- A graphic showing chart outlines/numbers.
- A table, listing the charts that countries have already signed up for in terms of either production or distribution. (A series of more detailed and current tables are noted below.)
Actions from the last meeting:
The Chairman requested that all participants respond back to him by
15 May 2003 on three matters:
- who their primary point of contact will be for this project (send full contact information)
- what countries will take responsibility for the charts still lacking sponsors?
- dates as to when those charts would be produced and distributed
Subsequent and recent activities:
The INT Chart Committee is working very closely with the Electronic Chart Committee. Identification of “Producer” States is the first goal and is currently being finalized. In order to proceed with both INT and Electronic Chart activities, it is considered beneficial to produce both the INT chart and the ENC either concurrently or at least within as close a time frame as possible. Since a number of States use automated methods to produce the paper INT chart, making the corresponding ENC is a relatively simple task in these instances, especially when compiling small-scale charts.
The MACHC INT Chart Committee considers small-scale INT charts a priority. The Electronic Chart Committee is approaching the goal of producing ENCs in a similar fashion as the INT Chart Committee. Since these tasks are so closely linked, it is imperative that the INT Chart “Producer” States be identified without delay so that a compilation/production schedule can be developed. The following tables provide current information on the planned INT charts in the greater MACHC area.
Planned INT Charts of the MACHC Area:
- By Scale (from small to large scale)
- By INT Chart Number
- By Producer Country (in alphabetical order)
Note: For very small-scale charts (Smaller than 1:2,750,000) see INT Charts "By Scale."
