Integrating GIS & fieldwork for geoscience undergraduates Anne-Marie Nuttall School of Biological and Earth Sciences Liverpool John Moores University
Introduction Two case studies: Level 1 fieldtrip to Arran –First introduction to GIS Level 3 fieldtrip to Snowdonia –After completing GIS/Remote Sensing module
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
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
