Moorings (High Density) – 1.48% for Killinure assesment High density moorings can be assessed using the high resolution aerial imagery.This is done by digitising a polygon to assess the area of the mooring and calculatingthe total area of moorings as a percentage of the overall lake area.

Outfalls and off-takes – None of these features where discerned from the aerialimagery for Killinure although in other lake studies certain types of these featurescould be assessed using RS/GIS techniques.

Sediment extraction – 0.94% for Killinure assessment For Killinure areas of sediment extraction can be assessed using the aerialphotography and polygons created to measure the area. From the this the area as apercentage of the overall area is calculated. For deeper lakes and other areas withinthe lake supplementation with field work might be needed

Dumping – 0.19% for Killinure assessment Areas of dumping are assessed in the same way as the sediment extraction based onarea of dumping as a percentage of the overall lake area. For Killinure various areasof dumping can be discerned from the aerial imagery but supplementation byfieldwork would be needed.

Aquaculture – None of these features where discerned from the aerial imagery forKillinure although in other lake studies certain types of these features could beassessed using RS/GIS techniques.

Shore-based recreation – This will have to be assessed by other means than RS/GIS.

Boat Traffic and water sports – Activity footprint 5 for Killinure assessment An indication of the level can be discerned from the aerial imagery but fieldworkwould be required.
