Some are using the tilde mark '~' to indicate
'approximately'.<br>

Some are using '-' for between eg depth=0.5-0.7 for between
0.5 and 0.7.<br>

<div>Not opposition, but for tidal areas, isn't this going to
have the same problems of whether you mark the "coastline"
at the high- or low-tide line?</div>

<div>You'd probably need something along the lines of </div>
<div>Average_low-tide=0.8</div>
<div>Average_high-tide=1.9 </div>

The depth at the high tide mark would usually go from 0 to some
negative number. and average would be a negative number. <br>
<br>
The depth at the low tide mark would usually go from 0 to some
positive number. So it could be mapped depth=0-1 <br>
<br>
I would not map those. But it does raise the problem of using'-' for
'between' if there is any negative number to be used. <br>
<br>
Is using 'to' an acceptable method to represent 'between'? <br>
<br>
This comes out of the river navigation problem when I looked at what
people were doing for variable depths.<br>
--------------<br>
For tidal or seasonal etc I would only tag the expected range ..
thus <br>
<br>
<div>Average_low-tide=0.8</div>
<div>Average_high-tide=1.9 <br>
<br>
would become <br>
<br>
depth=0.8-1.9 (or 0.8to1.9)<br>
