The GB1900 project was a crowd-sourced initiative to create a gazetteer, released under an open licence, by transcribing and geolocating all the place names on the second edition County Series of six inch to one mile (i.e. 1:10,560) maps of Great Britain, published by Ordnance Survey between 1888 and 1914, and thus out of copyright.
The project is currently based at the University of Portsmouth, and is the provider of the website A Vision of Britain through Time. NB: A "GIS" is a geographic information system , which combines map information with statistical data to produce a visual picture of the iterations or popularity of a particular set of statistics, overlaid on a ...
The Ordnance Survey Great Britain County Series maps were produced from the 1840s to the 1890s by the Ordnance Survey, with revisions published until the 1940s.The series mapped the counties of Great Britain at both a six inch and twenty-five inch scale with accompanying acreage and land use information.
The Ordnance Survey National Grid reference system (OSGB), also known as British National Grid (BNG), [1] [2] is a system of geographic grid references, distinct from latitude and longitude, whereby any location in Great Britain can be described in terms of its distance from the origin (0, 0), which lies to the west of the Isles of Scilly.
Geograph Britain and Ireland is a web-based project, begun in March 2005, to create a freely accessible archive of geographically located photographs of Great Britain and Ireland. [1] Photographs in the Geograph collection are chosen to illustrate significant or typical features of each 1 km × 1 km (100 ha ) grid square in the Ordnance Survey ...
The Retriangulation of Great Britain was a triangulation project carried out between 1935 and 1962 that sought to improve the accuracy of maps of Great Britain. [1] Data gathered from the retriangulation replaced data gathered during the Principal Triangulation of Great Britain , which had been performed between 1783 and 1851.
Britannia is a county-by-county description of Great Britain and Ireland. It is a work of chorography : a study that relates landscape, geography, antiquarianism, and history. Rather than write a history, Camden wanted to describe in detail the Great Britain of his time, and to show how the traces of the past could be discerned in the existing ...
The Land Cover Map of Great Britain (1990) was the first comprehensive survey since the Second Land Use Survey. This used satellite imagery, with ground survey used for checking. [ 9 ] The end product is a digital dataset rather than paper mapping, providing classification of land cover types into 25 classes, at a 25m (or greater) resolution.
