All former Ordnance Survey mapping has now been removed from this website (for the full story, visit the Ordnance Survey page).
For an example of the images that were previously published using the Ordnance Survey mapping that I am now no longer allowed to use, click the thumbnail below for the small image mapping derived from OS 250,000 scale mapping (36kb jpeg).
Next, click the thumbnail below for an example of the large maps that were created with OS 1:50,000 scale mapping (216kb jpeg)
I am now using two sources of mapping. The first source of mapping is the OS One Inch Popular series 1921-1930 mapping which was been digitised and georeferenced to the National Grid by XYZ Digital Mapping Company which has supplied the mapping in association with the National Library of Scotland.
All property records have a small map which is displayed on the property page. Properties of over 2000 acres also have a large map which can be viewed by clicking the "Large Map" link. Large maps may be anything from 300kb to 1.5Mb in size.
The maps are obviously out of date by 80 years or so but in most cases this makes little difference to the essential understanding of where the boundaries of landholdings are located. The main features that are likely to mislead the viewer are the absence of modern roads (such as the new A9) and motorways, the very different urban settlement boundaries (particularly in the large cities), new reservoirs, and the presence of numerous railway lines that are no longer there.
For example, in the above map you can see the effects of this misalignment together with the apparently inexplicable "corridor" which is in fact a new bypass. The difference can be seen by looking at the same property plotted against a 25,000 scale background.
In addition, due to the different map projections used for these maps (based on Cassini's projection), landholding boundaries can appear out of alignment with rivers, coastlines and other linear features which they are supposed to follow. In many cases, it is a good idea to have a copy of the 1:50,000 OS Landranger (or better still, the 25,000 scale Explorer maps) map beside you if the identification of boundaries is critical.
The second source of mapping is the Quarter-inch OS maps 1921-1930. These are used to construct the small maps of larger landholdings (5000 acres and above). They are a rather fine set of maps but suffer from the same limitations as the One Inch series. They have been kindly supplied by the National Library of Scotland.
