To measure the settlement over time by stratum for a long period.SOLUTION: A settlement by layer measurement device 100 comprises: an observation data acquisition unit 110 that acquires observation data generated by observing, from the sky, changes over time of the vertical displacement of the surface of the ground and the vertical displacement of a structure built on the ground; a stratum data acquisition unit 120 that acquires stratum data of the strata composition of the ground in which a stratum supporting a leading end of the base of the structure is specified; and a derivation unit 130 that derives the settlement over time by stratum of the ground from the observation data and the stratum data.SELECTED DRAWING: Figure 2 【課題】長期に亘って地層別の経時的な沈下量を測定する。【解決手段】層別沈下量測定装置１００は、地盤の地表面の鉛直変位量及び地盤に構築された構造物の鉛直変位量の経時変化を上空から観測して作成した観測データを取得する観測データ取得部１１０と、構造物の基礎の先端部を支持する地層が特定されている地盤の地層構成の地層データを取得する地層データ取得部１２０と、観測データ及び地層データから地盤の地層別の経時的な沈下量を導出する導出部１３０と、を備えている。【選択図】図２
