Geomeatics

Pictured at the launch of the Geomatics Boundaries Guidance note were Paddy Shine; Helen Murray-O’Connor; and, Ben King.

The Geomatics Professional Group of the Society recently launched a series of geomatics client guides designed and formatted to quickly and concisely explain some of the fundamental theories and practices used in geomatics. The guides are useful for helping clients to better understand the nuances of subjects such as map projection scale factor, scale, laser scanning and boundary issues.

The first four in this series of client guides are:
Terrestrial Laser Scanning – Understanding an evolving survey technology
This guide explains some of the survey issues behind laser scanning and what a client can expect from this now ubiquitous survey data capture technology. As an enabling technology it will be of particular interest to clients involved in building information modelling (BIM).

Map Projection Scale Factor – Understand map projections and avoid the potential dangers of scale factor
This guide explains in lay professional language geomatics-related concepts such as local and national (ING and ITM) grid systems, scale error/distortion and the effects of linking into national mapping coordinate systems.

Scale – Let’s be clear about scale
This guide deals with the often-misunderstood concept of scale and its relationship to spatial accuracy, survey specifications (including a quick topographic survey specification) and client needs.

A clear impartial guide to Boundary Disputes – Property Registration, Property Dispute Resolution, Boundary Identification and Demarcation
This guide outlines how property boundaries are defined in Ireland and who defines them. It also provides advice on the best approach in the case of a boundary dispute.

Guidance note on boundaries
The Geomatics Boundaries Working Group has also launched an updated Society of Chartered Surveyors Ireland practice standard on boundaries entitled ‘Boundaries: Procedures for Boundary Identification, Demarcation and Dispute Resolution in Ireland’ (2nd edition, guidance note). This guidance note is essential reading for all Society members interested in boundary dispute practice and may act as an effective refresher for experienced practitioners. It focuses on the different stages of a potential boundary dispute and the processes that a Society member should follow as an example of best practice. The new inclusions in this second edition extend the review of general boundary concepts and descriptions to include an outline on the nature of deeds/deed maps and titles, and the interpretation of deed descriptions and deed maps. It explores specific registration difficulties in substrata, airspace and multi-storey developments.

Both the client guides and guidance note are based on similar guides to those produced by the RICS but have been adapted for use in Ireland. Society members are encouraged to make use of these guides, which can be downloaded directly from www.scsi.ie.
