itime engineering, fishery, environmental monitoring, laying of submarine cables or pipelines, and the
development of electronic navigation charts, the results can also be an important basis for maritime
boundary delimitation decisions and safeguarding maritime rights and interests.

During 2021, in cooperation with the overall dispatch of domestic scientific research ships, the survey

ship "LEGEND" under the Ministry of Science and Technology completed the survey of the seas off the
shore of Hsinchu, Miaoli and Pingtung (Bashi Strait), and completed 2,720 km of submarine topographic
mapping, seabed sediment detection and 13 core sampling work. Furthermore, MOI also conducted ba-
sic survey operations for the 16,324 km survey line in the seas around Penghu, Kinmen and Matsu. The re-

sults 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 2021, the TENCC has completed 103 charts, including 27 coastal charts (UB3),
53 nearshore charts (UB4), 17 port charts (UB5), and 6 berthing charts (UB6) in the waters surrounding
Taiwan. More than 850,000 charts have been sold and used by more than 19,000 vessels.

In order to fulfill the responsibilities and obligations of coastal states and improve the navigation
safety of vessels entering and leaving Taiwan’s ports and seas, the Maritime and Port Bureau, TENCC
assists domestic maritime patrol, scientific research, port affairs and other official ships to load electron-
ic navigation charts, and TENCC also provides government departments with multiple applications in

vessel control, radar intelligence system, transportation safety investigation, disaster prevention and
rescue, ecological conservation and coastal management through the interfacing with basic maps and
customized maps by 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.
