Aerial laser scanning (ALS) data collected over an area of around 1 square km in Dublin city in 2007 (see satellite image). A total of ~225 million points were acquired for a dense urban neighbourhood. ALS was carried out by contractors using FLI-MAP 2 system. The system operated at a scan angle of 60 degrees, with an angular spacing of 60/1000 degrees between pulses. The FLI-MAP 2 system also provides spectral data in two different forms: (i) intensity and (ii) colour. An intensity value is provided for each point while colour information is provided by cameras acquiring images during the flyover and is transferred to scan points. The flying altitude varied between ~380-480m, with an average value of ~400m. Total 44 flight strips were acquired and 2823 flight path points were recorded, providing instantaneous aircraft position over time.

The Dublin Town Planning Competition was held in 1914, with the aim to "elicit Plans and Reports of a preliminary and suggestive character, and thus obtain contributions and alternatives which may be of value towards the guidance of the future development of the City in its various directions". The Dublin civic survey report refers to the competition as the Aberdeen Competition, probably due to the prize for the best design which was presented by the Marquis of Aberdeen and Temair. Eight entries were submitted in total, each relating to the Greater Dublin area, taking in Howth, Glasnevin, Ashtown, Dundrum and Dalkey. The main headings for the proposals included: 1. Communications; 2. Housing; and 3. Metropolitan improvements. The submission by Patrick Abercrombie, Sydney Kelly and Arthur Kelly was awarded the prize in 1916. Due to major political and historical events, the winning entry was not officially published until 1922, with the final Civic Report not published until 1925. Out of the eight entries, only three are known to have survived.
