Part of UCD Library's Curran Collection, most of these postcards were published in 1916 in the immediate aftermath of the Insurrection. They provide an excellent contemporary pictorial record of the damage to the city; one showing a “before and after” photograph of Sackville (O'Connell) Street. Some are reproductions of “under fire” photos taken by the Daily Sketch photographer and published by Easons. Other series were produced by Hely's and Coleman's publishers. The collection contains 37 distinct postcards (as well as duplicates) collected by Constantine Curran.
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.
This collection consists largely of letters from Roger Casement to Captain Hans Boehm, during Casement's stay in Germany in 1915, as well as some associated material (photographs, medals) relating to his first contact with the German authorities in November and December 1914 and the formation of the Irish Brigade in 1915.
