- PublicationMinor Harbours of the East Coast of IrelandConsiderable progress in the engineering of maritime structures occurred between the 18th and 20th centuries in Ireland. While major harbours have been well documented, there remain considerable structures that due to their small size have been overlooked. These minor harbours represent a considerable source of information, many having originated through local efforts only to be later modified through government works in the 19th and 20th centuries. The danger posed to these structures from deterioration and rising sea levels is increasing and it is imperative to create accurate records for the appropriate management and conservation of these structures. An initial pilot study of Coliemore Harbour [1] was undertaken in 2014-15, which served to establish a provisional methodology for scanning procedures, using a Leica Geosystems LiDAR scanner, from which precise measurements and configurations of each structure can be catalogued and compared. The pilot study served to identify issues to be addressed to ensure the information captured is both complete and as widely transportable to alternative formats as possible for ease of access to a broader range of users.
425 - PublicationAugmented Maritime Histories: Text, Point, Line(2016-11-12)The coastline of Ireland has been embellished through the accretion of piers, jetties, quays and breakwaters to facilitate the ever-Â-evolving nature of the shipping and fishing industries in the past millennium. These structures represent a significant infrastructural system that has shaped local and national Irish culture for centuries. While Ireland’s major ports have been carefully documented and researched, much of this infrastructure, though once intrinsic to the economic wealth and welfare of local communities, has fallen into disrepair as the industries that once generated their development have been centralized to the major ports. With damage from the seas ever increasing, it has become critical to document these minor harbour structures to describe and elaborate the entwined nature of their development with the communities they had once served.

188 - PublicationTechnological transformations at Boatstrand Harbour(2016-12-10)The late nineteenth century was a revolutionary period for harbour construction in Ireland, principally due to the efforts of one man, Bindon Blood Stoney [1828-1909] the Chief Engineer to Dublin Port [1862-98]. Although portland cement, the primary ingredient of concrete, had been developed as early as 1820 it was not until Stoney’s audacious use of large scale precast concrete blocks to build the North Wall extension and Alexandra Basin [1871-84]1 at Dublin Port that the material gained sufficient credibility to engineers to wholly supplant the use of stone in maritime engineering works.
170 - PublicationLiving in the clouds: conceptual reconstructions of harbour structuresThe harbours of Ireland, under threat from deterioration and rising sea levels, are being documented using terrestrial LiDAR augmented by archival research to develop comprehensive histories and timeline models for public dissemination. While methods to extract legible three-dimensional models from scan data have been developed and such operational formats for heritage management are imperative, the need for this format in interpretive visualisations should be reconsidered. The paper aims to discuss these issues. Design/methodology/approach: Interpretive visualisations are forms of history making, where factual evidence is drawn together with conjecture to illustrate a plausible account of events, and differentiation between fact and conjecture is the key to their intellectual transparency. A procedure for superimposing conjectural reconstructions, generated using Rhinoceros and CloudCompare, on original scan data in Cyclone and visualised on a web-based viewer is discussed.Findings: Embellishing scan data with conjectural elements to visualise the evolution of harbours is advantageous for both research and public dissemination. The accuracy and density of the scans enables the interrogation of the harbour form and the irregular details, the latter in danger of generalisation if translated into parametric or mesh format. Equally, the ethereal quality of the point cloud conveys a sense of tentativeness, consistent with a provisional hypothesis. Finally, coding conjectural elements allows users to intuit the difference between fact and historical narrative. Originality/value: While various web-based point clouds viewers are used to disseminate research, the novelty here is the potential to develop didactic representations using point clouds that successfully capture a provisional thesis regarding each harbour’s evolution in an intellectually transparent manner to enable further inquiry.
