Dublin Airport is using data collected by laser scanning aircraft to accurately measure land surface elevation to help reduce the risk of flooding at the international transport hub. The specially commissioned survey by aerial mapping company Bluesky involved the capture of LiDAR (Light Detection and Ranging) data for the entire site and surrounding area as part of a Dublin Airport Drainage Masterplan (DMP).
Dublin Airport commissioned Bluesky to complete the LiDAR survey following a competitive tender process. Using aircraft mounted lasers Bluesky captured 50 centimetre point spaced height measurements across the complete campus and immediate vicinity. The captured height data was delivered in a variety of formats for use by the authority’s Drainage Masterplan consultants in InfoWorks ICM hydraulic modelling software. The Bluesky data will be used to inform modelling projects which will help understand the airport’s drainage network, analyse flood risk relating to rainfall events and measure capacity in local watercourses. The Bluesky LiDAR data will also be used to model the flow of contaminants relating to aircraft de-icing an operational requirement required by safety regulations during the winter season.www.bluesky-world.ie
