How to create a natural 'true colour' image from single Landsat-8 satellite image bands.
Posts about technology and archaeology, how we use it, how it works and the results it provides us with.
Five years on: Reflections on mobile GIS survey at Hatnub Quarry P in 2017
Results of the mobile GIS survey in 2017 at the Hatnub quarries and links to the published papers.
Fuel shortages, Google Maps and adapting your tools
How do we answer questions when the data exists but there's no direct access? A real-world solution to a fuel shortage problem encapsulates the answer.
Free high-resolution satellite imagery and how to find it.
Where can you find free high resolution satellite imagery for your project, which is the best imagery and what are the issues with it?
Finishing the map, georeferencing the pyramid of Djedefre
Georeferencing a map of the pyramid complex of Djedefre, wrestling with inaccuracies, residuals and RMSE.
Errors, inaccuracies, resolution and RMSE: Georeferencing a difficult map of Abu Rawash’s pyramid and cemeteries
What makes georeferencing historic maps difficult and how does the process work? Here I georeference a problematic map of Abu Rawash, pyramid and cemeteries, Egypt.
Wonky Giza pyramids: Oblique satellite imagery and georeferencing
Satellite imagery is very precise but can still exhibit parallax. This is a particular issue for georeferencing historic maps, demonstrated here with reference to the Giza Pyramids.
Shifting mastabas: Georeferencing a plan of a Fourth Dynasty Egyptian mastaba cemetery, at Abu Rawash.
How do archaeologists relate historic maps and plans to modern satellite imagery and maps? This post and video shows how a historic map of mastaba cemetery F at Abu Rawash, Egypt was georeferenced with ArcGIS.
Kinky Temples: Satellite imagery ‘fails’!
What happens when satellite imagery contains errors? Warping of the satellite imagery has left us with kinky temples at Deir el-Bahri.
Ditch that total station and grab your tablet? ArcGIS Collector and QGIS QField mobile-GIS survey apps reviewed.
How do the latest mobile-GIS apps measure up in the field? I review two new approaches to archaeological survey.
