Translation of "Surveyors" in Japanese

Was a colonel in the Topographical Engineers  – a specialist corps of military surveyors.

は、軍事測量士の専門軍団であるTopographicalEngineersの大佐でした。

Pretty soon along came to the village some strangely dressed people who called themselves surveyors; and they surveyed a line in front of my grandmother's little house.

それからまもなく幾人かの測量士と自称する変な服装をした人たちが集落にやってきて、祖母の小屋の前を測っていきました。
