Museum Booklet: A Land Through Time

Museum Booklet: A Land Through Time

The eighth in the Museum’s series of booklets is a follow-up to our successful Heritage Lottery-funded LiDAR project. This measured tiny differences in height of the land surface of part of the Bradford Hundred area by the reflected beams of lasers fired from a plane.

It produced amazingly detailed images of large numbers of features in the landscape that have...

This is not the end, and watch the video!

Our HLF funded project on Ancient Landscapes of the Bradford Hundred was set to run for the whole of 2013.  We’re at the end of the year, the project has been a great success, and we have some spectacular images of the 12 square km we have surveyed.

But this is not the end! We are planning further activities for 2014, so keep checking the blog.

In the meantime, view the...

Complex of features near Bath Road, Bradford on Avon

Complex of features near Bath Road, Bradford on Avon

Following our two field-trips, Roy has been working on LIDAR images covering the complex of features near Bath Road. Image 1 shows that a more regular system appears to come through under extreme lighting from the east.

This is an amazing image considering that some of the features are only 4″ high.

Gill’s visit to the National Monuments Record in Swindon

Gill’s visit to the National Monuments Record in Swindon

Museum members visited Swindon in August this year with Roy Canham to look at some of the magnificent collection of aerial photos in the care of the National Monument Record Office. The purpose of the visit was to compare aerial photos from the Swindon collection with images produced by the Museum’s LIDAR project. These images had...

Rob’s Field Walk, Saturday 26th October 2013

Rob’s Field Walk, Saturday 26th October 2013

The weather was kind to us as we set off from St Lawrence School armed with plots of the LIDAR survey. We passed near the site of the Roman villa and were soon looking at our first ancient field which showed up as three sides of a rectangle, only one of which marries up with a tithe boundary. Our next point of interest was a possible...

Zooming Out

Zooming Out

Entries on our blog so far have focused on areas of special interest, checking how data from the project may help us to understand how the landscape of Bradford Hundred may have developed over the last 3000 years.

It’s valuable to ‘zoom out’ and take a broader view. The image was processed in newly acquired software and...

Spectacular fields around Haugh Farm

Spectacular fields around Haugh Farm

Plotting of the ancient landscape detail from the Lidar survey is nearing completion. To aid this process, Ritchie Brown has produced 6 images from each kilometre square Lidar tile, each image processed from a different azimuth or compass point to show up archaeology from a range of lighting angles.

The results can be...

The Medieval Landscape Emerges

The Medieval Landscape Emerges

As work continues on plotting archaeology from the Lidar images, it’s clear that we will get a mapping of the prehistoric and Romano-British landscape. This was from the outset the main objective. There are now a few signs of a period in time that has defeated local archaeologists and historians, namely the form of the landscape since Domesday – Bradford Hundred in the Middle...

Map plotting uncovers new secrets

Map plotting uncovers new secrets

The previous blog described how we produce high quality images from the LIDAR for use in the plotting process. Recording archaeology is very much a mapping process. You need to know what’s been found and where. So we have started the plotting process using a GIS (Geographical Information System) in which we can plot archaeology using Ordnance Survey digital mapping as a...

Six Views Of Each Square Kilometre

Six Views Of Each Square Kilometre

One of our project team, Ritchie Brown, has developed some really superb methods for handling the Lidar data. Using a very complex Geographical Information System (GIS) called GRASS, he has produced high quality image files which reveal the surface detail in superb quality.

Celtic Fields

Celtic Fields

The aim of our project is to use the LIDAR system to bring to light the ancient landscape around Bradford on Avon. Our best hope has been to recover the location and plan of early field-systems. As an example, photo A (top left) records a set of prehistoric fields on Chitterne Down, Salisbury Plain, which shows...

Interpreting LIDAR data – it’s a question of light

Interpreting LIDAR data – it’s a question of light

Roy Canham reports on the importance of light:

Back in March Kate reported on the very rapid photographic survey we undertook right across the project area. The purpose was to record the condition of each field so that we had same measure of judging just what ground conditions were current at the time of the airborne LIDAR survey.

Shedding new light on our villages

Shedding new light on our villages

Our main aim in the Ancient Landscapes project is to use the LIDAR survey to reveal very early landscapes, some of it consisting of features dating from around 1000BC. But we are beginning to get detail of more recent patterns, in particular indications of settlements that have shrunken in size or changed shape. Winsley Church Farm,...

Interpreting Air Photographs

Interpreting Air Photographs

On Wednesday 20th March, Roy and Sophie led an Aerial Photography workshop for volunteers on the Ancient Landscapes project.  For those of you who aren’t actively involved with the project but like to keep up-to-date on its progress, here’s a brief explanation of how we will be using air photographs to supplement the LIDAR data.

Roy’s woodland survey

Roy’s woodland survey

On 5th March Ritchie and I did a quick survey of woodlands in the project area. This photo shows a part of Inwood, with a section of the prehistoric field-system showing up as a low bank. It was good to see that under winter conditions some 80% of the sky is visible looking up through the trees, explaining why the test area for LIDAR...

Initial LIDAR Findings!

Initial LIDAR Findings!

We now have some early results back from the LIDAR survey.  We chose a couple of small areas within our 12 sq km to test the quality of the data we were getting back and we have been thrilled with the results.  Here is an example.

The image shows an area south of Winsley. The land slopes down towards the River Avon – the...

Kate’s Field Checking Story

Kate’s Field Checking Story

In order to help with interpreting the LIDAR survey results, it is important to know the state of each field at the time of the survey.

Our LIDAR flight took place on Friday 11th January, but within a few days the whole area was covered by snow making it impossible to conduct a survey of the state of each field.  However, Roy...

Outing to Cheverell Down

On 2nd February, Roy took a small group onto Cheverell Down, part of the Salisbury Plain Training area, to view the remains of a substantial ancient field-system. This was show persons interested in the project the kind of archaeology we are hoping to detect locally – though not so extensively preserved.  This was a useful...
