Archeology is a time consuming field, finding areas of historic interest can be a great challenge. The majority of Archeological sites are hidden under layers of soil and vegetation and are often not discovered until the areas are unearthed during exploitation and construction.
Aerial remote sensing techniques have been used for decades in archaeology to identify sites of interest. Aerial imagery is an important source, captured for mapping of cultural heritage as well as investigating potential sites visible on the imagery.
The requirement within the archaeological community is rapidly increasing for products such as LiDAR and height data. Intensity values from LiDAR data can aid in finding regions of less compact soil than expected in these regions, this analysis can indicate the occurrence of old settlements. In several countries archaeologists have discovered a large number of new sites, many of these because they have been ‘hidden’ in woodlands or areas that are untouched by agricultural activities.
Bloms archive geospatial data (DTM’s and aerial imagery libraries) can be used as a resource for these projects, as well as new tailored data capture missions. Blom has used technology, expertise and competence to create dramatically new information to be interpreted and recorded by national bodies responsible for cultural heritage and also museums with a special focus on aerial archaeology.
