Photographic data regarding 444 builings in Dublin, Ireland, comprising primarily multi-layer images in Adobe PhotoShop (PSD) format. The majority of images consist of one or more photographic images that have been manpulated to create a single ortorectified image of a structure; a structure may be represented by more than one PSD file, such that 516 images in total are included in the dataset.

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.

Three datasets of images of approximately 1 square km of land area in Dublin City in 2007. Images were captured through use of the Fugro FLI-MAP family of LiDAR systems which capture LiDAR and still camera imagery simultaneously during a fly-over survey. Each dataset includes “forward” and “mapping” imagery comprising complementary data files in ECW and SDIA formats.

Nine Thom’s maps of the city and environs of Dublin from the collection of the School of Geography, Planning and Environmental Policy (GPEP). Printed by the Ordnance Survey for the Dublin publisher Alexander Thom from the six-inch map sheets 18 and 22, and dating from the late 19th century. The maps have been annotated with hand written dates made by Dr. Arnold Horner, formerly of GPEP, and based on information in J.H. Andrew’s article "Medium and message in early six-inch Irish Ordnance Maps: the case of Dublin city". These loose maps were originally published in Thom’s annual Almanac and Official Directory.
