RAC, Cirencester – 14th February 2012

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

Overview

There is no need to take notes:

There is every need to ask questions

DART

www.dartproject.info

Aiming to improve the science underpining the detection of subsurface archaeological features

Archaeological ProspectionWhat is the basis for detection

Archaeological ProspectionWhat 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 meNow you dont

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

Why DART? Precision agriculture

Why DART? Precision agriculture

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

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

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?

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

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

Why are we doing this – spreading the love

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

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

Why are we doing this – innovation

Reducing barriers to data and knowledge can improve innovation

Why are we doing this – education

To provide baseline exemplar data for teaching and learning

Why are we doing this – building our network

Find new ways to exploit our data

Develop contacts

Write more grant applications

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
