The following is a work in progress leading to a better understanding of the Lanscape from the Ice Age
The National Civil War Centre on Tues 6th November 2018.
We commenced our journey with the aim of unravelling the landscape development around Newark from the present day back into the Ice Age.
Evidence from topography, geology, archaeology and historical maps and documents will to be researched and Ursilla Spence, from Nottinghamshire County Council,introduced us to sources of potential material, such as Historical EnvironmentRecords(HER) and magic.defra.gov.uk, as well as using her considerable expertisewith a questions and answer session..
Following introductions and lunch Ian Ross, of the Ice Age Journeys team, gave a presentation of Geographic Information Systems , demonstrated Qgis, the computor mapping tool and attendees downloaded the programme onto their lap top for use..
QGIS is a free and open-source geographic information system that supports
viewing, editing, and analysis of geospatial data.
The outcome was that we attempted the following:-
1. Adjust QGIS for OSGB 1936 EPSG:27700 England’s CRS
2. Load a LiDAR tile
3. Make a virtual raster from several LiDAR tiles?
4. Analyse LiDAR by applying Hillshade
5. Load a background map, e.g. Google satellite tiles
6. Identify the Queen’s Sconce then find two further Civil War sconces
7. Demonstrate 3d imagery.
This is a community project and the measure of our success is not only to obtain our objectives but to include and support everyone no matter their background or previous familiarity of the work. This project will have considerable impact on our knowledge of landscape development and builds on our work with the previous Heritage Funded Project Ice Age Journeys. www.iceagejournys.org.uk and supported by the charity, Ice Age Insights.
This session was on Tues 4th December 2018: Colin Baker (author/ contributor to Mercian Geologist) –Coversands and investigating past landscape from borehole & auger records followed by Ian Ross in the afternoon..
This afternoon session included:
1.More on rasters
2. Joining LiDAR tiles together
3. Symbology – colours that represent height
4. Profile – cross section the landscape, e.g. sconces
5. Georeferencing Old Maps
6. Compare the old landscape with the new
7. An introduction to vector data
8. County & parish boundaries, rivers, geology
9 Practical GIS 2
Some of the above, but focusing on georeferencing
If you bring your own map you must have a related coordinate referenced raster – like
LiDAR or OS MasterMap
