    Biography

    Dr Conor Cahalane is a Lecturer in Remote Sensing at the Department of Geography, Maynooth University. His background is in Geomatics, Applied Computing and Geocomputation. Dr Cahalane employs satellite, airborne and UAV remotely sensed data for coastal management, environmental protection, engineering works, forestry surveys and precision agriculture. Conor currently is collaborating with Ordnance Survey Ireland developing a method for automated change detection and map updating using multi-band aerial imagery. Dr Cahalane sits on council for the Society of Chartered Surveyors promoting RS and EO in the Geomatics community in Ireland and was also the Irish MC member on COST Actions ES1309, investigating recent advances in satellites, UAVs and optical sensors.

    Research Interests

    My interests encompass both land and marine - ranging from passive and active remote sensing technologies including multispectral, hyperspectral, thermal, LiDAR and SAR. I utilise data from satellite, airborne, unmanned platforms and terrestrial platforms and combine this data with other spatial data-sets for additional contextual information. Fusing data from multiple sensors on a single platform is a major focus of our research.
