What 測量士 do
An English description is being prepared. Japanese description:
測量計画を立て、現地に出向いて、専門の機器や技術を使って地形や位置を測量、結果を計算して、工事に必要な基準点を正確に設定する。地図をつくるための測量を行うことも仕事の一つである。人工衛星やコンピュータ、ドローンを利用した高精度の測量器械も使われており、迅速・正確に測量・計算できるようになっている。デジタル地図や地理情報システム(GIS)の利用・活用によるデジタルマッピングも行われている。
工事の着工の前には、国家三角点という日本全国にある基準点から測量器械を使って現場近くに測点を導き出し、工事の基準点を設定する。また、電子基準点から現場近くに測点を設置し、正確な位置を設定する。工事が本格化すると、構造物の細部の位置を決めて型枠を組めるように印を付ける「墨出し」や、掘削作業の仕上がり中心線や高さの基準などを示す「丁張り」など、細部測量を行う。
測量ミスや計算ミスは許されないため、慎重に何度もチェックする必要がある。
◇ よく使う道具、機材、情報技術等

Today ¥5.43M → in 3 years ¥5.92M → in 5 years ¥6.26M → in 10 years ¥7.23M (10-year range ¥6.22M–¥8.39M). The model assumes pay growth of +2.9% per year.
What drives the annual growth rate
Projected pay = current pay × (1 + annual growth)^years. The annual growth rate starts from a base wage-growth rate and adds or subtracts labor demand (the job-openings-to-applicants ratio), wage momentum and AI replacement risk for each occupation. Projections are not guarantees. How it is calculated →

Will AI replace 測量士? AI replacement risk
How AI is changing this job
A written analysis for this occupation is being prepared.
AI replacement risk compares the parts of a job that are easy to hand to AI or software (processing information, documentation, repetitive computer work) with the parts that are hard to automate (physical work, working closely with people, judgment in unpredictable settings), using the MHLW job tag survey on work activities, work context, skills and knowledge. The result is a relative position among all occupations in the country, scaled to 0–100%. Methodology →
Labor demand for 測量士
A ratio above 1.0 means there are more job openings than applicants (a labor shortage). The 5- and 10-year figures are estimates from the openings ratio, wage momentum and AI replacement risk.

Guidance from job tag (Japanese)
技術者として基本測量又は公共測量に従事する者は、測量法の規定により「測量士」又は「測量士補」の資格が必要となる。資格取得には、学歴と実務経験年数によって、申請だけで済む場合と、試験を受ける場合とがある。一旦測量士補の資格を取ってから、改めて測量士の資格を取る人もいる。資格を得て、国土地理院に登録することで「測量士」若しくは「測量士補」と認められる。
測量事務所、建設会社、不動産会社等に雇用されている間に測量士の資格を取り、経験を積んだ後に独立して測量事務所を開設するケースも見られる。関連する「土地家屋調査士」の資格を取得する者もいる。
