Waterland–People: On Structure and Origin of Crannogs ...

5.2. SITE PLANS CHAPTER 5. RESULTS AND ANALYSIS
this section represent the underlying Ordnance Survey maps that are available online
(Digimap 2008) and are coloured in grey. The overlying plans in black are plots of the
actual shorelines at the time of the survey in June/July 2008. For orientation, EI layouts
and grid lines along with GPR traverses are plotted in colour.
5.2.1 Loch Wasdale Crannog
The grid crossed the center of the crannog and was then enhanced into the S for the
investigations on the related mounds (s. Fig. 5.5).

5.2.2 Loch Bosquoy Crannog
The grid was laid out in parallel to the SW corner and the W shoreline that was roughly
straight and from there advanced into the center that lay inside the walls. EI layout had
to be done in such a way, that the lines of electrodes would neither rest on, nor cross
over high walls, while for the radar instrument, it turned out to be impossible to centerly
