1 Introducing 3-D computer visualization models in an Earth Science undergraduate mapping training class Ken McCaffrey University of Durham

2 Project outcomes A GEES small Learning and Teaching award 3-D ArcView and gOcad models of the Assynt mapping region An evaluation of the effectiveness of the 3-D model for fieldwork teaching Modification of models in light of staff and student feedback A resource that can be useful to other institutions given the significance of the Moine Thrust zone

3 The Fieldcourse Loch Assynt Mapping Area 8 day, Level 2 field-course Main mapping training course for Geologists

4 Methodology Construct digital terrain model (DTM) using available topographic data (OS Digimap data) Drape existing field data and Landsat/Aerial photos onto the DTM Include new DGPS-located contact information mapped using field-GIS on hand-held computer Use gOcad software create surfaces that represent the geological structure Develop demonstration exercises for field trip During the field class, in the evenings, the model progressively revealed to students in step with their own mapping on a lap-top with a data projector

5 Differential GPS mapping Map boundaries to sub -1m accuracy Data direct into GIS in field

6 Test Model #1

7 A test model

8 Test Model #2

13 Whats next Improved imagery Boundaries mapped in detail Surfaces created in gOcad Finalised model(s) by end-summer Implement on field course (end Sept) Improve model based on feedback

14 e-MapScholar – a resource containing tools, learning and teaching materials that use geo-spatial data, including Digimap data Invited to provide an Earth Science Case Study In place of Bristol Project in Field Studies module, will introduce a Lake District Digital Geology Project Learning outcomes Construct a digital geological model of the Lake District using OS, geological and geophysical data Construct a digital geological model of the Lake District using OS, geological and geophysical data Interpret features of the model Interpret features of the model Gain an appreciation of the geological structure of the Lake District before their field trip Gain an appreciation of the geological structure of the Lake District before their field trip
