NO6H0921 Oslo (scale 1:3,500)

last brand new ENC produced (28/11/2023 edition : 1)

Today marks a significant milestone as Primar released the twenty thousandth ENC cell.

The PRIMAR database now proudly houses 20,034 ENC cells

 

note : 633 cells have been replaced and/or withdrawn since 2004-02-22

 

IHO membership :

in green IHO member states / in yellow Non member coastal state

 

79 international IHO Hydrographic Offices in the Primar catalogue 

but a couple of Hydrographic Offices (available in the AVCS Admiralty catalogue) are missing :

• LK - Sri Lanka : 7 ENCs
  
• MM - Myanmar : 4 ENCs
  
• TH - Thailand : 40 ENCs
  

For info, it's worth noting that some countries don't deliver the same data to Primar and UKHO 

Ex.: (Primar vs AVCS UKHO)

- Indonesia ID (539 vs 581 cells including 56 less / 14 more) ...

- China CN/C1 (504 CN vs 41 CN cells but 0 C1 vs 499 C1 cells)

- Vietnam VN/V1/V2 (72 V1 vs 4 V1 cells / 13 VN vs 0 VN cells / 0 V2 vs 44 V2 cells)

 

By the way, some GB ENCs (97 cells) created with mixed copyrights between UKHO, and other international Hydrographic offices or organisms are not available in the Primar catalogue.

Actually, UKHO receives ENCs from IC-ENC and PRIMAR RENCs but also directly from national hydrographic offices who do not want to distribute their ENCs via a RENC (Primar or IC-ENC), and provides ENC services for the end user.

 

Today, the Primar ENC catalogue now exceeds 17,000 ENCs (17,019 worldwide references of official @IHOhydro nautical vector charts).
