Desk based assessments

What is the chance that something of archaeological value is in the ground?  Before work begins that is potentially destructive for the ‘ground archive’ (archaeological remains still in the ground) it’s a good idea to estimate how likely it is that finds worthy of preserving will be encountered.  

We do that by examination of the archaeological prospects for the region in question based on known finds and geographical situation. Archaeological literature and the  Dutch Central archaeological information system (Archis) are consulted for discoveries on the terrain and direct neighbourhood. Local archaeologists and historians can also supply information.The presence (or absence) of finds is brought in relation to cartographic details. This can mean historical, geological and geomorphological mapping.
