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.
A collection of material related to the Easter Rising 1916 from the IBVM (Loreto) Institute & Irish Province Archives, including contemporaneous accounts of the Rising as observed by the Loreto Sisters at St Stephen’s Green Dublin and Loreto Abbey Rathfarnham. The material is collated from three separate Loreto archival collections: the community archives of Loreto Abbey Rathfarnham; Loreto College, 53 St Stephen’s Green; and M.

The Workhouse Drawings collection contains a representative sample of drawings, plans, and documents drawn from the Irish Architecture Archive's Workhouse Collection. The Workhouse Collection (reference 85/138) in the Irish Architectural Archive includes surviving drawings for workhouses built in Ireland to provide relief for the poor. Built between 1839 and 1847, the workhouses were designed in a Tudor domestic idiom by architect George Wilkinson. Occasionally drawings are accompanied by other documents including the standard printed specification or, more rarely, items of correspondence. Many are in extremely poor condition and their extreme fragility precludes public access. This online collection provides access to drawings and documents relating to the Mallow, Castleblayney, Lismore, and Gorey workhouses. The drawings for Mallow Workhouse may be considered a representative set of the surviving drawings for the Tudor style workhouses built by Wilkinson. The majority of the drawings were produced mechanically (engraved and printed). The inclusion of drawings from Castleblayney, Lismore, and Gorey, in addition to those of Mallow, ensures that this online collection includes samples of each printed drawing.
