what does ∼ mean on land registry map?

    I've been trying to find out what that symbol " ∼ " depicts on the OS 25" land registry map . Mostly I see it on what I assume are doorways to houses but in other places too like roadways and fields. Does it represent an entrance of some sort? or maybe a control point for surveying equipment?

    The symbol itself is a little bigger than the one above.
    Thanks Wazzo.

    Seems to be consistently located around footpaths and ditches and ponds - that kind of thing. Maybe it indicates that they're drawn "freehand" or by eye rather than surveyed precisely as the boundaries and buildings might have been?

    There are a few old houses near me, and my own house pre-dates the map, the symbol corresponds with the entrances to the houses where it intersects them, but the symbols do appear in other places even the middle of roads.

    Thinks the term is used in maths, though its two of the symbols, one on top of the other, indicating rounded values ie. 4.77~5 or 9.13~9. I would assume that its not exact measurements

    Kind of used as an equal sign, but to show that some accuracy has been lost. As someone said, maybe its been drawn freehand or maybe no exact measurement has been readily available so they just guessed

    Looks like the Area Brace Symbol to me. Used by the OS to identify adjacent features which have been measured together to give parcel areas.

    That symbol that you are inquiring about signifies that line attached to that symbol is included in the field area.

    Thanks, that was an old question!! I eventually discovered what it meant. I had asked many professionals, solicitors, engineers and architects. It's surprising how many didn't have a clue!
