Have you heard of the Tellus survey? It may be relevant to you.
Conducted by the Geological Survey of Ireland (GSI), the Tellus survey collects geophysical and geochemical data on rocks, soil and water across Ireland. 

The Tellus website

When surveys take place, the aircraft will flies at a low level of 60 metres over rural areas rising to 240 metres over urban areas.
