http://www.see.leeds.ac.uk/virtual-landscapes/ Virtual Landscapes Project  Screen-based virtual reality environments, created using the Unity 3D game engine software  Aims:  Enhance geological field and map skills  Develop 3D visualisation skills  Accessible parallel provision field trips  www.see.leeds.ac.uk/virtual-landscapes/  serc.carleton.edu/teachearth/activities/197181 .html

http://www.see.leeds.ac.uk/virtual-landscapes/ Project Background  Update an older web-based exercise  Worked initially with Leeds Arts University  Created by geologists not games designers…  Background coding and so loading/ running speeds not optimised!  Unity updates regularly with older versions becoming obsolete making landscapes difficult to edit

http://www.see.leeds.ac.uk/virtual-landscapes/ How to use  Play online or download for PC and Mac:  3D geological maps  3D topographic map  Lighthouse Bay  Download only for PC and Mac:  Rhoscolyn, Anglesey  Download only for PC and older Mac OS*:  Three River Hills *Possible to use apps that allow PC content to run on Mac – more details from Mark

http://www.see.leeds.ac.uk/virtual-landscapes/ Geological Mapping and Field Skills Lighthouse Bay, Three River Hills and Rhoscolyn Designed as an in-class exercise with paper field slip and notebook Map a virtual landscape populated with rock outcrops Tasks: produce a geological map, cross section, stratigraphic column and field report

http://www.see.leeds.ac.uk/virtual-landscapes/ Basic mapping skills • GPS, how to use coordinates to locate features on a map and how to add data readings to a field slip, symbols used etc. Dead sheep!

http://www.see.leeds.ac.uk/virtual-landscapes/ Lighthouse Bay Conformable sequence of sediments dipping 090/22N Takes 2 to 4 hours to map depending on experience 33 outcrops

http://www.see.leeds.ac.uk/virtual-landscapes/ Lighthouse Bay Stratigraphy Fine grained, cross bedded sandstone Fossiliferous limestone (Upper Jurassic) Black shales Fossiliferous limestone (Lower-mid Jurassic) Coarse grained sandstone with graded bedding

http://www.see.leeds.ac.uk/virtual-landscapes/ Lighthouse Bay Reading the landscape Outcrop colour matches rock type Vegetation varies with rock type

http://www.see.leeds.ac.uk/virtual-landscapes/ Lighthouse Bay Short exercise suggestion: Look at the vegetation can you identify a pattern? How might this help you identify the underlying geology? Find an outcrop in each type of vegetation. Does this confirm or disprove your theory?

http://www.see.leeds.ac.uk/virtual-landscapes/ Lighthouse Bay Short exercise suggestion: Map one boundary by walking the area then construct the boundary using structure contours and compare the two

http://www.see.leeds.ac.uk/virtual-landscapes/ Three River Hills Complex geology – including a syncline with an overturned and sheared out limb 2 – 3 days to map whole area depending on experience (over 100 outcrops) Minibus “teleport” from beach to hill top

http://www.see.leeds.ac.uk/virtual-landscapes/ Three River Hills Short exercise suggestion: Map a transect along the northern river and draw the cross section

http://www.see.leeds.ac.uk/virtual-landscapes/ Three River Hills Field sketches include important information! In this case the same beds are now overturned and deformed.

http://www.see.leeds.ac.uk/virtual-landscapes/ Three River Hills Short exercise suggestion: Short exercise suggestion: Map the normal fault using the Map the west coast to just east of the compass to follow it along strike normal fault – look at outcrop pattern of shallow dipping units and topography

http://www.see.leeds.ac.uk/virtual-landscapes/ Virtual Rhoscolyn, Anglesey Two versions: 1) a mapping exercise created for an accessible field class 2) an online version of a year 2 structural geology field class

http://www.see.leeds.ac.uk/virtual-landscapes/ Virtual Rhoscolyn, Anglesey Quartzite Boundary mapping aided by Thin bedded topography and vegetation semi-pelites and pelites Outcrops are part of the texture of the landscape rather than blocks Notebooks are flags for data

http://www.see.leeds.ac.uk/virtual-landscapes/ Virtual Rhoscolyn, Anglesey  Sequence of folded and cleaved meta-sediments  Map as a simple asymmetric anticline  Add in cleavage data  Plot and analyse data on stereonets  Add in discussion of 3D models  Curved structure contours

http://www.see.leeds.ac.uk/virtual-landscapes/ Virtual Rhoscolyn field class  Uses a Rhoscolyn virtual landscape with 3D models but no embedded data  Extensive field data are supplied separately  Includes interpretation of progressive and polyphase deformations  Teaching materials at: https://homepages.see.leeds.ac.uk/~eargel/ VirtualRhoscolyn  Contact : Geoff Lloyd for more info and answers G.E.Lloyd@leeds.ac.uk

http://www.see.leeds.ac.uk/virtual-landscapes/ Topographic 3D model  Simple model to introduce students to working with maps  Potential questions for the map  Where are the highest and lowest points?  How far above sea level in metres are you when standing on the highest point?  Identify the steepest and shallowest slopes  Draw a topographic profile and describe what you would see as you walk along it  Check out your answers in the 3D world

http://www.see.leeds.ac.uk/virtual-landscapes/ Geological 3D models  Two versions:  Dip – use keys 1-6 to change dip from 0°,11°, 22°, 45°, 67°, 90°  Strike – use keys 1-8 to change strike by 45°  Ask students to create their own outcrop pattern ‘rules’, e.g.:  By looking at how the change in dip effects the apparent thickness of a unit  By comparing the outcrop patterns in the valleys as strike and dip varies

http://www.see.leeds.ac.uk/virtual-landscapes/ Observations from the classroom  Students make the same mistakes they make when learning in the field  Wander round the landscape with no clear plan  “Outcrop capture” – plot on all the outcrops then worry about the interpretation  Focus on data readings only; fail to record additional information in notebooks, particularly from the sketches
