The purpose of this work was to identify potential habitat pressure points within freshwater Special Areas of Conservation (SAC), to assist with the development of Conservation Management Plans (CMPs) for each site.

A medium format camera (Leica RCD30 60mp aerial survey camera) was used to capture nadir orthophoto tiles at 4cm resolution, provided in GeoTIFF format. The acquisition of imagery for each site was confined to the SAC boundary. Flight plans followed the course of the river with an aim to ensure that the middle of the water course remained centrally in each frame, and to guarantee a 60m coverage of river banks.</div><div>&nbsp;</div><div>Flight dates for River Roe and Tributaries SAC are as follows; 11/09/2019, 16/09/2019 &amp; 17/09/2019.</div><div>&nbsp;</div><div>&nbsp;</div><div><strong><u>Specifications&nbsp;</u></strong></div><div>Nadir Aerial Imagery Camera Camera System - Leica RCD30&nbsp;</div><div>Operating Height - 350m Resolution (Ground Sample Distance) - 4cm&nbsp;</div><div>Forward / side overlap - 60% / 30%&nbsp;</div><div>Flight Line Separation - 245m&nbsp;</div><div>Positioning and navigation - Integrated Applanix System POS AV 510 GPS/IMU&nbsp;</div><div>&nbsp;</div><div>LiDAR and Oblique imagery, also collected for each freshwater site, this can be requested by contacting&nbsp;<a href='mailto:NIEA.GIS@daera-ni.gov.uk' target='_blank' rel='nofollow ugc noopener noreferrer'>NIEA.GIS@daera-ni.gov.uk</a></div><div>Further details, including those related to further image processing can also be requested by contacting&nbsp;<a href='mailto:NIEA.GIS@daera-ni.gov.uk' target='_blank' rel='nofollow ugc noopener noreferrer'>NIEA.GIS@daera-ni.gov.uk</a></div></div><div style='font-family:&quot;Avenir Next W01&quot;, &quot;Avenir Next W00&quot;, &quot;Avenir Next&quot;, Avenir, &quot;Helvetica Neue&quot;, sans-serif; font-size:16px;'><br />&nbsp;</div>" ;
