20,417 km survey line in the seas around Penghu. The results not only provided Taiwan's electronic
navigation charts, but also gradually enriched the basic spatial data of Taiwan's waters and provided
various value-added applications.

3. Performing the International Issuance of Electronic Navigation Charts
The MOI established the Taiwan Electronic Navigation Chart Center (TENCC) on November 15,

2018, which is responsible for producing, publishing, and maintaining electronic navigation charts (ENC).
Taiwan’s ENCs are formally distributed to countries around the world through the Norwegian Regional
Electronic Navigation Chart Coordination Center operated by the Norwegian Hydrographic Service,
PRIMAR. As of the end of 2022, the TENCC had completed 108 charts, including 30 coastal charts (UB3),

53 nearshore charts (UB4), 19 port charts (UB5), and 6 berthing charts (UB6) in the waters surrounding
Taiwan. More than 1.59 million charts have been sold and used by more than 20 thousand vessels.

In order to fulfill the responsibilities and obligations of coastal states and impr o v e the navi-
gation safety of vessels entering and leaving Taiwan’s ports and seas, the Maritime and Port Bureau,

TENCC assists domestic maritime patrol, scientific research, and port affairs, and helps other official
ships to load electronic navigation charts; in addition, the TENCC also provides government depart-
ments with multiple applications in vessel control, radar intelligence system, transportation safety
investigation, disaster prevention and rescue, ecological conservation, and coastal management by

interfacing with basic maps and customized maps through the electronic navigation chart web map
service (ENC WMS).

Furthermore, responding to the demand for international issuance and maintenance of ENCs
in the future, in addition to continuing to execute ENC measurement, updating, and maintenance

operations, we will also actively participate in related international technical working groups or con-
ferences to strengthen mapping expertise and display the achievements of Taiwan’s ENC issuance.
Such deeds will further increase the positive effects of international participation.
