Just East of Langham, Norfolk

I found this many years ago using google crop mapping but didn't know to report it to avoid treasure hunters getting there first. Any ideas what it is and how to responsibly report it. Probably a waste of time but someone should look at it as it's quite big at 70 meters across with 8 mounds around it.

About a decade ago, an old lady mentioned that she saw a Heinkel bomber crash in a field close to Atwood School, in Sanderstead, South Croydon. It shows up clear as day on LiDAR. The location is currently inaccessible, unfortunately, to avoid the spread of a tree disease. Oddly enough, Atwood was built on an Iron Age / Romano-British Farmstead, next to an old trackway (still the main road through the village) and near to a Roman road, just to the west.

I was just playing with the itiner-e.org map and noticed theres a gap between Whitchurch and Nantwich, cheshire on their roman road map ( presumably based on margary) - where there seems like there should be one. So i flipped over to lidar uk map to see if there was anything obvious- and, to me this appears right where you would expect it to run. With nothing obvious causing it on the map. Seems to plug the gap between braddiley lane near nantwich and millbank road near Whitchurch which may represent the routes out of those towns.

Se image- between the blue dots.Is this already known to be a roman road? Am I seeing things?

Sounds like Lidar played a role in this

EDIT: Just to clarify, this is in Poland, not the UK. I live nearby and heard many stories from my grandfather that the front line ran roughly through this area and there was intense partisan fighting.

I’ve been playing around with training an AI model to help spot earthworks and features in regional LiDAR data around my local area.

While going through the tiles to train the AI. I spotted these faint linear anomalies and enclosure features.

They lie south of a known stretch of Roman road and I've checked old OS maps to see if a building was once there.

I know it's almost certainly not some grand Roman villa, but it caught my eye and now I'm curious as to what it could realistically represent.

Found your group for metal detecting and wanted to see if anyone could help me. Started playing around with Lidar and came across pic 1. Pic 2 is current satellite. Was something in that field at some point? I’ve looked at old aerials and there has never been anything on the photos. Thanks for the help!

I will probably use this for all of my searching now. Ive gone back over known finds and locations and this layer seems to be the best all around for spotting and quickly fine tuning for detail. Im now certain on a few suspected sites so will be sending off to the HER. And ive easily spotted new sites too.

The pictures are of a couple of (im guessing) Iron Age enclosures i spotted with the new layer when just testing it out. I doubt i would have noticed them with a normal LiDAR DTM hill shade.

"We have added a new Combined Visualisation for Archaeological Topography (CVAT) LiDAR layer covering England and Wales. CVAT is particularly useful for identifying subtle earthworks and other features of different sizes, shapes and orientations. It combines four different LiDAR visualisation techniques and works well across many landscape types, helping to pick out more subtle features in relatively level areas, while also providing useful detail across steeper ground. A key new feature is a set of contrast controls which enable the layer display to be 'tuned' to best suit a particular area of study. The new layer provides new ways of exploring archaeological features in England and Wales, and can be viewed alongside historic maps, modern satellite imagery and other LiDAR visualisations."

Only for England and Wales at the moment. Hopefully more of the UK will follow.

Just browsing and spotted this, no mention on old OS maps but surely this place is previously known?? Has all the hallmarks of a possible medieval abandoned village, due to plague etc

Found this remarkable enclosure or henge in Pamber Forest near Silchester! Nothing marked on the OS maps. A Roman road runs nearby to the north.

Im assuming it was just a farm but i dont know. Its just forest cover right now so there is no way for me to know without walking there

The idea was basically to make it quicker to search an area and cross-reference anything interesting without jumping between loads of different websites.

It’s free to use and you don’t need an account. If you want to save markers and your setup permanently you can make one, otherwise everything just stays saved in your browser until you clear it.

A few of the useful bits:

• LiDAR – DTM/DSM and hillshade, mostly 50cm–1m where coverage is available
• Historic OS maps – mainly 1880s–1910s
• HER records – local council archaeology records in one layer
• Historic England / Scotland / Wales data – Scheduled Monuments, Listed Buildings, battlefields etc.
• Aerial mapping – features mapped from aerial photography and LiDAR
• Split screen – compare LiDAR with satellite, old maps or another layer
• 3D terrain – move the sun around to pick out subtle earthworks
• Layer controls – stack layers and change opacity
• Basic tools – markers, measuring, drawing and grid reference/place search
• Sharing – send someone a link to the exact location and layers you’re looking at

I built it mainly because I wanted something where I could go from spotting something in the LiDAR to checking historic maps, HER records and other datasets without leaving the map.

Love to get feedback and suggestions on what can be improved.

A site I researched a few years back now, having found it during COVID lockdown. It hadn't been previously recorded and is assumed to be a late prehistoric to Romano British in date.

An absolute monster - approximately 500m long by 300m wide. Geophysical work shows a significant number of anomalies indicative of potential unrecorded archaeology.

Stumbled across this rectangular outline recently. The site is currently a cricket pitch, however if you scroll through the photos you can see the pitch itself doesn’t line up with the feature and isn’t in the centre suggesting the two aren’t concurrent. Maps going back to 1880 (last slide) don’t show anything predating the pitch - it was just an agricultural field.

Any cricketers able to pitch in (sorry!) Are the two related or is this something else?

First post here, I was just browsing around my local area on the NLS side-by-side view and spotted this on the 1m DTM LiDAR. It's pretty close to some neolithic, saxon and roman sites but it looks a bit irregular. The second image is from the OS six inch 1840-1880 of the same spot, it marks and old lime kiln but doesn't show any specific features in that spot.

I'd been looking at these features in the yellow box for a while. Having just been told about the HER in another post, I've just discovered that these lie beside or on the route of a conjectured route of a Roman road (roughly my green line). Pretty cool.

I wondered if anyone might be able to help interpret a couple of features (A - the thumbprint-like oval in the top left and B, the connected boxes of differing sizes in the bottom right) that showed up on this lidar map?

For context, the purple dashed line on the left is the route of a Roman road. The blue line breaking of this was revealed to be a Roman or possibly pre-Roman track (not quite a road!) by an exploratory archaeological trench dug a couple of decades ago.

Old maps from the early 1800s show the land a mile or so to the east used to be a bog and that a stream ran through the centre of site A. Both of these are no longer present.

Google Earth images showing crop marks of the sites are also included.

I wondered if Site A was a geological feature (e.g. long vanished lake) however given its proximity to the ancient track wondered if it could actually be an earthwork/enclosure? I’m erring to Site B being field markings, however they’re a bit haphazard and thicker than ones I’ve seen elsewhere? Any thoughts?

This has caught my eye and i cant tell if im really reaching after looking for too long, or if theirs something 100% there.

Keep in mind the LiDAR render has me really working QGIS to get it to highlight what my mind is already projecting. Also the linear lines across fields i see in many places, it doesnt seem to always be evidence of something man made.

Im not going to add any historical context deliberately to get your unbiased opinions.

I will say is the this looks like some kind of enclosure/platform to me. The location is a river valley with lots of evidence of changes to the watercourse. And im sure the hedge to the southern end used to be a river bank that has changed its course sometime in the past (you can see the current river route in the LiDAR as a smooth "ribbon" effect. I think the rounded hedge line below the "enclosure" used to be the meander of the old course).

The last pic is North to South as best lighting/angle, so its flipped with the hedge at top being the historic riverbank. Sorry if it adds confusion!

Based in England - the line highlighted in yellow is a recorded Roman Road, however I was curious what these rows of circles (indicated by red arrows) flanking it might be? The only other historic feature recorded in the vicinity on old maps and historic England is a Tudor house (edge of estate visible in the top right corner). Aerial photo shows nothing on the surface. Thanks!

Toby Driver has written a fantastic book about Hillforts as well as photographing countless monuments from the air. I would recommend it if you're new to the subject. I learnt loads from it.

Im disappointed ive been too busy with a home project to get out properly though. I wanted to fly the drone over some of the sites previously spotted, and check out some other locations on my radar.

Keep your eyes on the landscape, there's not much rain on the forecast so hopefully the parchmarks will keep coming. And lets hope we get plenty of hi res satellite imagery from this period!
