Geospatial Research opportunities at DIT, Ireland (Masters level)

Dear colleague,

I would be grateful if you would circulate details of two research (at Masters level) opportunities here at the Dublin Institute of Technology (DIT), Ireland. Research would normally take two years and the student would receive a scholarship of Euro 12,500 per year.

The candidate should normally hold an honours bachelors degree at level 2.1 or higher (Enquiries relating to equivalence of qualifications may be directed via the URL below).

The projects must begin before the end of October 2006. Please feel free to pass this notice to colleagues.

Details of the projects, together with application instructions, may be found at

http://www.dit.ie/DIT/study/graduate/research/built.html

I have included the abstracts below.

With my best regards

Developments of Algorithms for the Identification of Building Surface Types from Terrestrial Laser Scanner Return Intensity Measurements

ABSTRACT

Terrestrial laser scanning is a rapidly-developing technology that acquires three-dimensional coordinates of objects quickly, remotely, automatically and systematically. The hardware is becoming ever more sophisticated and portable, and the dedicated software required to process the large volumes of data collected is developing. Applications of terrestrial laser scanning include the measurement of complex structures and the mapping of national monuments for maintenance/archiving purposes. Currently, most research relates to geometric accuracy evaluation and 3D information extraction from the raw data.

Many systems record laser return intensity in addition to three-dimensional coordinates but, to date, little research has been carried-out on return intensity. The principal factors that influence return intensity are distance to object and surface reflectivity which, in turn, is related to surface type. Accordingly, it is proposed to develop algorithms that relate terrestrial laser scanner return intensity to surface type, particularly with respect to buildings. From this a building surface type classification algorithm, based on terrestrial laser scanner return intensity, will be developed and evaluated. Should it prove successful, this research would enable more information to be extracted from terrestrial laser scanner data than is currently the case and would, therefore, improve the utilization of this rapid and non-contact technology for the surveying of buildings.

Extraction of Physical and Environmental Information for Irish Roads from Airbourne Laser Scanner Data (LiDAR-Roads)

ABSTRACT

The proposed project will evaluate the performance of airborne laser scanning (LiDAR) technology in determining key spatial data related to roads. LiDAR data consists of spatially referenced 3D point information in the form of a cloud of high accuracy and closely spaced object points acquired from an aircraft (helicopter or fixed wing) flying once over and along a road axis at flying heights from 100 m to 2000 m. The high accuracy and close spacing of the points means that this technology has the potential of automatically or semi-automatically yielding a variety of important road data such as road geometry, surface condition, location and dimensions of road objects (road signs, traffic lights and other fixed objects), type, location and dimensions of adjacent vegetation, buildings and overhead cables. Such data will contribute to the improved management of Irish roads and the efficient planning of remedial/improvement works, particularly relevant in the context of road safety.

The project will exploit extensive existing LiDAR data sets (Department of Spatial Information Sciences) at various flying heights. It will report on the systematic and random accuracies of the road data resulting from detailed scientific comparison between the processed LiDAR data and rigorously verified ground truth.
