GEOGG141: Principles and Practice of Remote Sensing (PPRS)

Masters module: 15 credits

Staff: Dr. Mat Disney (MD) (convenor, UCL Geog), Dr. Jose Gomez-Dans (JGD), Prof. Philip Lewis (just Lewis, PL).

Moodle: GEOGG141 but note these pages are the most up-to-date resource for this module.

Aims

  • To provide knowledge and understanding of the basic concepts, principles and applications of remote sensing, particularly the geometric and radiometric principles;
  • To provide examples of applications of principles to a variety of topics in remote sensing, particularly related to data collection, radiation, resolution, sampling, mission choices.
  • To introduce the principles of the radiative transfer problem in heterogeneous media, as an example application of fundamental principles.

    Content
    The module will provide an introduction to the basic concepts and principles of remote sensing. It will include 3 components: i) geometric principles of remote sensing: geodetic principles and datums, reference systems, mapping projections distortions and transformations; data acquisition methods; ii) radiometric principles remote sensing: electromagnetic radiation; basic laws of electromagnetic radiation; absorption, reflection and emission; atmospheric effects; radiation interactions with the surface, fundamentals of radiative transfer in heterogeneous media (vegetation); orbits; spatial, spectral, temporal, angular and radiometric resolution; data pre-processing; scanners; iii) time-resolved remote sensing including: RADAR principles; the RADAR equation; RADAR resolution; phase information and SAR interferometry; LIDAR remote sensing, the LIDAR equation and applications.

    Assessment
    3 hour unseen examination, which takes place at the start of Term 2. The examination will be a combination of essay-type and problem-solving questions. Candidates will answer four questions from a choice of seven in a three hour unseen exam. See course handout above for more details, but some past papers with model answers for 2008-2013 are given below (NOTE: the course code, content, and exam format have varied over time, most recently in 2014, where the mapping parts have been removed):

  • Jan 2008
  • Jan 2009
  • Jan 2010
  • Jan 2011
  • Jan 2012
  • Jan 2013, note this was a DRAFT QA paper (not all Qs match final paper)
  • Jan 2014
  • Jan 2015
  • Seminars T1 2016

  • Tues 15/11/16 13-14:00, PB305 (top floor from the north entrance of Pearson): Dr. Dirk Gorissen, from Oxford spin-out robotics company Oxbotica, will talk about some of their work on autonomous vehicles, & also about his work with UAVs for orangutan conservation
  • Tues 22/11/16 17-18:00, PBG07: Justin Moat, from Kew Gardens. Justin will show some of Kew's work in 3D lidar scanning of rare and iconic trees for preservation and management, as well as other UAV work, and remote sensing and GIS applications for tree conservation
  • Tues 6/12/2016 17-18:00, PBG07: Charlotte Bishop, one of our MSc graduates, now working for CGG (via Nigel Press Associates) to talk about recent mapping and geoscience activities (and opportunities).

    Other talks TBD which I'll advertise here and via email etc. We also encourage you to attend the Industrial seminar series arranged in CEGE, on a Thursday evening. We also have physical Geography seminars on a Thursday lunchtime in G07 - some of these may be of interest, and again I'll try and let you know - all welcome to those.

    Journal articles

    PDFs of the papers below, and others (particularly for the radiative transfer lectures) are kept here. This is by no means a comprehensive list and is only intended to give a flavour of some of the literature in these areas.

    READ!

    An excellent summary of key RS principles and examples produced by the Canadian Centre for Remote Sensing. This is available online or as a 250 page 13MB pdf file, so is quite detailed and comprehensive.
