Over the years, the INT scheme for Region M was maintained / improved by PWGCA then HCA under the IHB coordination. This and the INT chart production status have regularly been published in IHO publication S-11 Part B Region M. At its 6th Conference (Punta Arenas, Chile, Nov. 2006), HCA tasked the IHB to develop ENC schemes at small and medium scales for Region M. As a result, small scale (Overview-1 and General-2) and medium scale (Coastal-3) ENC schemes were agreed by HCA in 2007 and 2009, respectively. It was further assumed that an ENC producer HO would be that of the equivalent INT chart. At its 12th Conference (

Current status of INT chart scheming and production in Region M is reflected in S-11 Part B (http://www.iho.int/iho_pubs/standard/S-11/S-11.htm).
