[mkgmap-dev] Need help with string handling in mkgmap

Thu Feb 15 17:40:54 GMT 2018

If you look at my screenshot, you will see the left power turbines will 
be shown as "Senvion (153 Mm)" whilst the right power turbines will be 
shown as "Senvion (143m)". So it seems to me, that there is no really 
guide line how to put in the value of height or elevation in the osm 
map. And i simply want to get rid of the letter "M", to have shown all 
values in the same way. And i thought as it was suggested in the style 
manual on page 15, use the substitution filter "subst" to delete the 
letter "m", which is a part of the value for height or elevation. From 
the manual i was not sure of the correct syntax ...

I will use your other hint with the conv filter and see, what will be 
the result from this.
