Large scale land consolidation has taken place in West-Friesland from the early 1960s until the present day. From the start it was recognised that land consolidation posed a threat to the archaeological remains in the area, especially as it was often combined with the flattening of the landscape and intensification of agricultural practice. It was thought that after the land consolidation had taken place almost all of the archaeological remains would be destroyed. Aerial photography was seen as an important tool to monitor this development, especially as its outcome can be tested against other survey techniques and excavations. The interesting outcome of the research was the assessment that although destruction took place there were still a reasonable amount of archaeological remains present, which needed management in the future.
