我國電子航行圖測製發行流程

Procedures for Taiwan Electronic Navigational Charts

"為善盡沿海國維護船舶航行安全之責任與義務，內政部於107年11月15日成立「臺灣電子航行圖中心」，專職負責電子航行圖之測製、發行、更新及維運，並於108年2月14日起正式透過由挪威國家測繪局運作的區域電子航行圖協調中心（PRIMAR）對國內外發行我國電子航行圖。臺灣電子航行圖中心依循國際海道測量組織（International Hydrographic Organization, IHO）訂定之國際規範，透過資料庫管理模式，系統性處理水深測量成果、整合各項圖資基礎資料，建立標準化電子航行圖製圖與檢核程序。本文將簡要說明我國電子航行圖基礎資料來源及其檢核評估原則、水深資料處理、圖徵物件編輯及圖資產品檢核等測製發行流程。截至110年10月25日止，我國總計已出版100幅電子航行圖，除持續提供圖資更新服務，後續將產製符合國際S-100系列最新標準電子航行圖及多元資料產品，推進下世代電子航行圖的發展。"

"Taiwan ENC Center (TENCC), established by the Ministry of the Interior (MOI) on November 15th, 2018, is the authorized hydrographic office responsible for the production, publication and maintenance of Electronic Navigational Charts (ENCs). ENC data of MOI is formally distributed via the Regional ENC Coordination Center (RENC), PRIMAR, operated by the Norwegian Hydrographic Service. Following international standards, TENCC has established a database-based standard procedure to systematically process hydrographic survey data and integrate data from various sources. This article will briefly explain the procedure from source data collection and verification, bathymetry processing, feature encoding and compilation, to ENC product verification, etc. As of October 25 2021, TENCC has published 100 ENC cells and has been continuously providing prompt ENC updating services. The next focus will be the development of S-100 based data products including digital nautical publications to be used together with the next generation ENCs. "
