A presentation given by Anthony Beck at the Royal Agricultural College, Cirencester on 14th February 2012. This presentation describes the data collected by the DART project and encourages members of the local communities to exploit this data. It covers data, formats, licences, software, applications. This introductory presentation was followed up with an afternoon hands-on workshop.

2. Overview
•To give you a quick overview of DART
•To describe our data
•To make this data available to you
•To describe how you can use this data

3. Overview
There is no need to take notes:

There is every need to ask questions

4. DART
www.dartproject.info
Aiming to improve the science underpining the detection of
subsurface archaeological features

5. Archaeological Prospection
What is the basis for detection

6. Archaeological Prospection
What is the basis for detection
Micro-Topographic variations
Soil Marks
• variation in mineralogy and
moisture properties
Differential Crop Marks
• constraint on root depth and
moisture availability changing
crop stress/vigour
Proxy Thaw Marks
• Exploitation of different thermal
capacities of objects expressed
in the visual component as
thaw marks
Now you see me
dont

8. Why DART? ‘Things’ are not well understood
Environmental processes
Sensor responses (particularly new
sensors)
Constraining factors (soil, crops etc.)
Bias and spatial variability
Techniques are scaling!
• Geophysics!
IMPACTS ON
• Deployment
• Management

9. Why DART? Precision agriculture

10. Why DART? Precision agriculture

11. Why DART? Traditional AP exemplar

12. Why DART? Traditional AP exemplar

13. Why DART? Traditional AP exemplar
Significant bias in its application
• in the environmental areas where it is
productive (for example clay
environments tend not to be
responsive)
• Surveys don’t tend to be systematic
• Interpretation tends to be more art
than science

14. What do we do about this?
Go back to first principles:
• Understand the phenomena
• Understand the sensor
characteristics
• Understand the relationship
between the sensor and the
phenomena
• Understand the processes better
• Understand when to apply
techniques

15. What do we do about this? Understand the
phenomena
How does the object generate an
observable contrast to it's local
matrix?
• Physical
• Chemical
• Biological
• etc
Are the contrasts permanent or
transitory?

16. What do we do about this? Understand the
phenomena
If transitory why are they
occurring?
• Is it changes in?
• Soil type
• Land management
• Soil moisture
• Temperature
• Nutrient availability
• Crop type
• Crop growth stage

17. What do we do about this? Understand the
relationship between the sensor and the phenomena

18. What do we do about this? Understand the
relationship between the sensor and the phenomena

30. Data
All held on a hard-drive
Subset of the full research data we will make the rest of this available through
the server
It contains
Raw data
Processed data
Metadata
Formats
Standard interoperable formats
Licences
These are not complete
Most data will be made available under an open re-use licence (see server)
Creative Commons
GPL

31. Server (in the near future)
The full project archive will be available from the server
Raw Data
Processed Data
Web Services
Will also include
TDR data
Weather data
Subsurface temperature data
Soil analyses
spectro-radiometry transects
Crop analyses
Excavation data
In-situ photos

32. Software
Software
Proprietary
You will know what this is so I wont talk about it

33. Why are we doing this – spreading the love

34. Why are we doing this – it’s the right thing to do
DART is a publically funded project
Publically funded data should provide benefit to the public

35. Why are we doing this – IMPACT/unlocking potential
More people use the data then there is improved impact
Better financial and intellectual return for the investors

36. Why are we doing this – innovation
Reducing barriers to data and knowledge can improve
innovation

37. Why are we doing this – education
To provide baseline exemplar data for teaching and learning

38. Why are we doing this – building our network
Find new ways to exploit our data
Develop contacts
Write more grant applications

39. What do we want from you
Acknowledge our project
Reference our data
That's it
It would be nice to include us in other projects
This is not a requirement
It would be nice if you let our funding bodies know that you've
used (and hopefully liked) our data
