The invention relates to a method of, and system (200) for, obtaining an indication of the soil strength of soil (100) over which a compactor roller (10) travels. The method includes determining the depth to which a drum (14) of the compactor roller (10) penetrates into and depresses the soil (100) when the compactor roller (10) travels over a soil surface. The system (200) includes a compactor roller (10), a measuring arrangement (40) and a processor (50) which is operatively connected to the measuring arrangement (40) and which is configured to process data received from the measuring arrangement (40). The measuring arrangement (40) includes an inertia! measurement unit (70, 72, 74) which is operatively connected to the compactor roller (10), wherein the arrangement (40) is configured to obtain an indication of the soil strength of soil (100) over which the compactor roller (10) travels during operation, by determining the depth to which the drum (14) penetrates into and depresses the soil (100) over which it travels. |
