Introduction
to ArcGIS
What is GIS?
A general purpose and extensible computer
system handling data pertaining to
geographical locations
(D.Rhind)
Where something is?
What is at a given location?
55◦ North, 2◦ West
Coarse (small scale)
Detailed (large scale)
GIS map comprises layers
• Points represent
localities or data points
we might collect
• Shapes/polygons
represent geological
units
• Lines represent contacts
or faults etc
Co-ordinate systems
Latitude/Longitude

A 3D digital geology map
Lake District Digital Map Project
Aims
• To produce a 3D digital geological
map/model of the Lake District
• To relate geology of the Lake District to its
landscape in preparation for our visit there
Planning!
Tips for a successful project
• Group Project
• Strategy to achieve milestones
– Week 1 – Learn/revise GIS and produce initial map
– Week 2 – Add geology to map and make some interpretations
– Week 3 – Finish interpretations and start report
– Week 4 – Complete project deliverable
• Logistical items
– Data management
• Technical items
– Background reading
• Next week in lecture will get more info on the form of
the report (submit report via digital drop box on Duo)

Assignment
• Group report – submitted via Duo in Field
studies click on Tools button to find Digital
Drop Box
• 1 report per group
• Format – A Word file no longer than 4 A4
sized printable pages
• Do not submit data files or
ArcMap/ArcScene files
• An illustrated report giving your
interpretations will earn more marks than
lots of material copies from text books!
