Geomatics

The UCL Geomatics Section is involved in the science, engineering and modelling of measurements and data relating to Earth and its environment.

About

Ranging from space-based measurements of the Earth (and other planets) using radio waves, down to micron level observations using lasers and optical techniques, the Geomatics Section forms part of the larger Department of Civil, Environmental & Geomatic Engineering. The department is noted for the width of its remit by comparison with “traditional engineering” departments elsewhere, incorporating leading research into such diverse elements as transport economics, public health, infrastructure, design, water resources management and earthquake engineering. The Geomatics staff both contribute to and benefit from this diverse research environment.

Dr Claire Ellul

Having previously worked as a GIS consultant, my research interests now include spatial databases and approaches for handling large quantities of spatial data. Additionally, I am currently conducting research into the integration of 3D GIS and spatial databases, examining issues relating to topology and performance. I am also involved in a number of Spatial Data Infrastructures projects, seeking to identify the most suitable mechanisms to share data amongst academic staff in an interdisciplinary, multi-national context. As part of this, I am investigating approaches to building usable systems to facilitate data discovery and evaluation, as well as to ensure metadata capture and maintenance processes are integrated into data manipulation tasks.

Research 

The Geomatics group is involved in the science, engineering and modelling of measurements and data relating to Earth and its environment. The Geomatics staff are informally organised into three groups according to research theme: Geodesy and Navigation; Photogrammetry, 3D Imaging and Metrology; and GIS. Click on the groups below to see their research topics and current projects.

Geodesy and Navigation

The research work in geodesy and navigation consists of finding new solutions to challenging positioning problems, as well overcoming geodetic challenges that result from the ubiquity of positioning systems. Key research themes include advanced orbit and clock modelling, novel precise positioning applications, robust multisensor positioning and navigation, and coordinate systems such as VORF and SnakeGrid.

  • SnakeGrid: The development of low-distortion 2D coordinate systems for engineering projects such as railways that extend over hundreds of kilometres of the Earth’s surface. Visit SnakeGrid's website.
  • Vertical Offshore Reference Frames (VORF): The development of high resolution transformation surface models to provide the link between GPS/GNSS positioning and offshore reference levels such as Chart Datum and Mean Sea Level. Visit VORF's research group page
  • Robust Positioning and Navigation: A series of projects focused on novel techniques for improving the performance of GNSS and multi-sensor navigation and positioning systems under challenging reception conditions, such as in dense urban areas and under jamming. See further information below. 
Photogrammetry, 3D Imaging and Metrology

The photogrammetry and imaging group focuses on the acquisition and analysis of accurate and reliable measurements using techniques such as imagery and laser scanning, and applies these to natural and man-made objects across a range of application areas. 

  • 3D Imaging: We test sensor accuracy, develop new calibration strategies and develop new applications for 3D cameras. Visit Photogrammetry and 3d Imaging's website. 
  • BIM: Building Information Modelling has been gaining momentum recently in the UK construction industry, especially with impending government legislation that encourages the use of this process on their contracts. Visit Building Information Modelling's webpages

The work of the GIS group ranges from social applications of geospatial technology – as exemplified by the Extreme Citizen Science project – to research into technical aspects such as database infrastructure and mathematical algorithms for data mining. 

  • Extreme Citizen Science: ExCiteS: UCL's interdisciplinary research group on Extreme Citizen Science
  • SpaceTimeLab: The SpaceTimeLab promotes and enhances research on spatio-temporal complexity in society, economics and engineering. 
  • Adaptable Suburbs: A study of the relationship between networks of human activity and the changing form of urban and suburban centres through time
