This is one of a series of articles which give photographs of features on the ground which have standard symbols on Ordnance Survey 1:25,000 maps, and also show the symbol. See OS 25K map symbolsExternal link for introduction to the series, and links to other articles in it. Ordnance Survey have told us that although the symbols are copyright they allow them to be copied without charge or specific licence.

Click on a photo thumbnail to see a page (in a new window) with a larger photo, and other photo details. The photo page also has a section of the 1:50,000 Ordnance Survey map; click on that map to see an Ordnance Survey Get-a-map section of 1:25,000 scale map. The Get-a-map link in the notes column displays the map, but not in a new window - use the browser back button to return to this article.

"General features" include places of worship, other buildings, masts, lighthouses, slopes and pits (which have a separate heading in this article as there is more discussion of their symbols). Many of the features in this section are in the Land feature symbols on 50K mapsExternal link. Some features which have symbols on 50K have no symbol on 25K - for example: pipeline with flow direction; ruin (building outline without colour infill); chimney (small circle) - not specified in 25K symbol key but symbol looks the same; heliport (H symbol on 50K, word on 25K); Graticule intersection at 5' intervals (not shown on 25K). Some "land features" on the key to 50K symbols appear in other sections of the 25K symbols key - for example woodland, National Trust properties.

Some abbreviations are in the OS key to symbols. We have a separate abbreviations articleExternal link showing which are used on 25K and 50K scale maps, and giving examples with links to Geograph photos. There are examples of the abbreviations listed in the OS key to 25K symbols.

Presumably this is because the pit is still being worked, so contours will change over time.
