SCSI Geomatics Surveying Professional Group Launch Guidance Documents


The Society of Chartered Surveyors Ireland’s Geomatics Surveying Professional Group has just launched four Geomatics Client Guides and a Geomatics Guidance Note covering the areas of scale factor, scale, laser scanning and boundary issues.

The Geomatics Surveying Professional Group represents professionals involved in the science and study of spatially related information. The world of Geomatics is sometimes seen as complex, and often opaque, to a non-surveyor audience. These guides are designed and formatted to quickly and concisely explain some of the fundamental theories and practices used in Geomatics.

The first four in this series of Client Guides include:

Terrestrial Laser Scanning – Understanding an evolving survey technology
This client guide explains some of the survey issues behind laser scanning and what a client can really 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 client guide seeks to explain 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 co-ordinate 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.

The Geomatics Boundaries Working Group has also launched an updated SCSI 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 SCSI 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 an SCSI member should follow as an example of best practice.

The new inclusions in this 2nd 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 the Guidance Note are based on similar guides as those produced by RICS but have been adapted for use in Ireland.  SCSI members are encouraged to actively use these guides or share them with clients; they are available for download directly from
