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.

Data recovered from the project "Historic Ireland's Build Environment and Road Network Inventory Access" (HIBERNIA), which had been a web enablement of two earlier inventories: the Dublin Environmental Inventory (DEI) and the Dublin Docklands area master plan inventory (DDAMP) (both undertaken by the School of Architecture, Landscape and Civil Engineering, University College Dublin). The combined inventories include historical, geographical, and architectural information collected from 1993 to 1995 for 1,280 of Dublin's buildings.

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.

The Workhouse Drawings collection contains a representative sample of drawings, plans, and documents drawn from the Irish Architectural 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.

This collection of documents relating to Douglas Hyde comprises of Hyde's memoir and a collection of postcards. Hyde's memoir is in four parts, composed at various periods in 1918-19, mostly when he was ill and confined to bed. It looks back on various aspects of his career in the Irish language movement. The first part of the memoir is 9 pages long and in it Hyde writes of the politicisation of the Gaelic League and his subsequent resignation as President. Part 2 has 44 pages and discusses the Irish Language movement and the resignation of 'Sceilg', the columnist J. J. O'Kelly, at the 'Freeman's Journal'. Part 3 is 21 pages long and in it Hyde discusses the politicisation of the Coiste Gnóha or Executive Committee, the nature of this committee, and the gradual weakening of his own position. Part 4 is 19 pages long and recalls Hyde's first encounter with Thomas O'Neill Russell in 1877, O'Neill Russell's bitter attack on Michael Logan, editor of the American newspaper 'An Gaodhal', on points of grammar, his argumentative personality and his general lack of a sense of proportion. A collection of illustrated postcards with some miscellaneous items, in two sections: 1) Douglas Hyde: Some 60 items, mainly of correspondence, mostly illustrated postcards, in a variety of languages, dated mainly 1895-1938.

Also included are two illustrated postcards sent by Hyde to Mrs Ethel Chance, Birmingham, a family friend, from San Francisco in February 1906. 2) Liam de Róiste: Some 30 postcards, mainly dated 1911-12, relating to his work as Secretary of Coláiste na Mumhan, the Irish College in Béal Átha an Ghaorthaidh (Ballingeary), Co.
