In the example below, I've screengrabbed some of the townlands of Aghada parish, which overlook Cobh Harbour and lie about 5km southwest of Midleton, in East Cork. The older map, on the left, captures Aghada as surveyed in 1841-42 and published in 1845. The map on the right shows the same area as surveyed in 1896-97, and was published in 1902. In the intervening years, the small rural community had hardly changed, except perhaps for a bit of development around the pier. Even today, despite a bigger population and a good sprinkling of housing along some of the old roads, the layout of the area has hardly altered.
