  1. Integrating GIS & fieldwork for geoscience undergraduates Anne-Marie Nuttall School of Biological and Earth Sciences Liverpool John Moores University

  2. Introduction • Two case studies: • Level 1 fieldtrip to Arran • First introduction to GIS • Level 3 fieldtrip to Snowdonia • After completing GIS/Remote Sensing module

  3. Benefits of using GIS at Level 1 • Initial orientation & familiarisation with field area • day-by-day record of field sites • overview of how sites relate to each other • appreciation of topography & sense of scale • interpretation of contours & gradients • appreciation of software & GIS concepts for future use

  4. Level 3 - Spatial modelling • Hypothesis: glacier formation is more likely on high-elevation, north-facing slopes • Input data: Digital Elevation Model (DEM) of Snowdonia • Calculate all grid cells with northerly orientation and > 600 m.a.s.l. • Overlay results on satellite image

  5. Web resources: • Digimap (to download OS map & DEM data): http://digimap.edina.ac.uk • Landmap (satellite image coverage of the UK): http://www.landmap.ac.uk • ERDAS Imagine (Image processing software): http://www.erdas.co.uk • CHEST (university licensing for all of the above): http://www.chest.ac.uk • National Remote Sensing Centre (purchase of satellite images): http://www.nrsc.co.uk
