Here’s What We Hope to do in 1 Hour
• Explore Spatial and Temporal Dimensions in Humanities Scholarship
• What Can Be Done?
• What Principles To Be Aware of?
• Some Useful Tools
Grounding Ourselves
• How do we get from:
• there to here
• then to now
• what can we learn from the path we take?
• What data do you have?
• What questions do you want to ask?
• Pure Speculation

What About the Path and Sequence?
• Because we are representing real world phenomenon we have have to ask what we are seeing when we identify patterns.• Trends• Shifting• Stabilising• Cyclic vs anomalies
• Burst

• So what we see are that there are some great visualisations out there
• and that the power exists to create them
• ...but where do they come from?
• The place we have been talking about all day
• ...good data...
• so how do we find and manipulate data related to space and time to make it usable in such ways?
• Process is a Way of Thinking, not a Substitute for Thinking
• Data needs to be considered and reported in Context
• Look Before you Leap - Get to Know Your Data
• Question Everything - Collection, Process, Bias, etc.
• Coincidence is Not the Same as Causality
• Just Because Data Exists Doesn’t Mean its Relevant
Data Analysis Principles
Fern Halper - Seven Guiding Principles
Time
• Time series data can be continuous or discrete
• It’s usually discrete - i.e. observations exist for regularly or irregularly spaced intervals
• Although occasionally continuous - i.e. an observation at every instant of time
Processing
• Balance Sources and Formatting
• Filtering
• Normalising
• De-Duplication
• Unit Conversion
• Time Zones
• Formats
• Testing and Removing or Resolving Anomalies
Analysis versus Presentation
• Who is this for?
• Is it to convey a message or finding?
• Is it purely for discovery and analysis?
• Maps can be funny to manipulate

But Time is ‘Funny’ and let’s consider Back to the Future
• There can be simple sequential linear tine ... it’s the one we are most used to

But with simplication we see than time is not linear in this case ...

And it really is matter of what we are representing
