The mapping of ‘areas where no archaeological
heritage is expected’ in Flanders (Belgium)Meylemans E.,
Flanders Heritage Agency
Introduction
Background:
-New legislation: ‘immovable heritage decree july 12- 2013.
-Archaeological legislation effective 2016:
>scheduling of archaeological sites;
>designation of ‘Archaeological Zones’ (other surface criteria for preventive
archaeology);
>legislational framework for metal detecting;
>preventive archaeology based on surface area criteria (difference in/
outside protected areas/ Archaeological Zones/ other areas);
>preventive archaeology fully commercialized through system of
‘acknowledged’ archaeologists;
>framework for ‘chance finds’;
>designation of ‘areas where no archaeology is expected’: periodic
update
Background (‘decision tree’):
Map of Designated ‘areas where no archaeology is
expected’
Online publication: https://geo.onroerenderfgoed.be/
Map of Designated ‘areas where no archaeology is
expected’-What?
>2 dimensional design!!! > every ‘area’ is declared free from archaeological
preventive research no matter how deep the building development;
>areas where soil disturbances have occurred with ‘deep impact’;
>areas where archeological trial trenching of excavations were performed
and where the archaeology has been ‘fully excavated’ or where no (or no
significant) archaeological heritage was present;
THUS: areas where is is shown that no (significant) archaeological heritage is present or has
been preserved; no ‘gradation’;
-But, not taken into account:
>The presence of middle paleolithic archaeology is not taken fully into account;
>the possible presence of remains of ‘deep structures’ (for example water
wells).
Some complexities; example: (alluvial) areas with buried
archaeological heritage
Some complexities; example: areas with thick and complex
archaeological stratigraphy (for example historic towns)
Some complexities; example: areas with valuable archaeologicalheritage but which have been ‘cleared’ for further preventivearchaeology
Map of Designated ‘areas where no archaeology is
expected’-Sources: Belgian soil map; high resolution digital terrain model of Flanders: mapping of large
‘disturbed’ areas, for example through sand or clay extraction.
-Archaeological archives (Central archaeological Inventory).
Map of Designated ‘areas where no archaeology is
expected’-Sources: third party information (for example local archaeological services)
Map of ‘areas where no archaeology is expected’: some

Map of Designated ‘areas where no archaeology is
expected’-Future?
>Continued importation of data from preventive archaeology;
>Towards a 3D map? > to exclude needless archaeological preventive archaeology
and to include the middle paleolithic heritage.
>Inclusion of other sources (for example erosion maps)?
>Inclusion of ‘gradation’ in disturbances? (for example agricultural impact)?
