Permanent Survey Mark: A Side Note of FIG WW 2025

「國際測量師聯盟2025工作周會議」（FIG Working Week 2025, FIG WW 2025）於2025年4月6日至10日，在澳洲昆士蘭州布里斯班市（Brisbane, Queensland, Australia）舉行。昆士蘭州政府為表彰此一重要活動，於會場附近設置了一個特別設計的永久性測量標誌（Permanent Survey Mark, PSM）。根據主辦方的公告：「這個具有里程碑意義的裝置強調了測量和空間科學在城市發展、基礎設施專案和土地管理中的關鍵作用」。本文由與會之所見，記述此一事蹟，並以2023年於「舊金山潮位站」所見類似功能之一個測量標，以及昆士蘭州政府土地、製圖與測量博物館所展示之多種式樣測量標，彙整介紹該地之測量標。

The ''FIG Working Week 2025'' (FIG WW 2025) was held from April 6 to 10, 2025, in Brisbane, Queensland, Australia. To commemorate this significant event, the Queensland Government has installed a specially designed Permanent Survey Mark (PSM) near the conference venue. According to the organizers' announcement: ''This landmark installation underscores the critical role of surveying and spatial sciences in urban development, infrastructure projects, and land management.'' This article documents the event as witnessed by the author and introduces the survey mark, along with a mark of similar function observed previously in 2023 at the ''San Francisco Tide Station'' and other marks exhibited at the Museum of Lands, Mapping and Surveying, offering a collective overview of survey marks in the region.
