[mkgmap-dev] Is height: filter working as described?

Sat Feb 4 12:03:15 GMT 2017

Hi Carlos,

to answer your question: my understanding is that you should  not use the height filter.
I did not try but I think something like conv:m=>ft|conv:ft=>m should extract the raw
value in m, so maybe something like this:
ele=* {set ele_in_m='(${ele|conv:m=>ft|conv:ft=>m})'
natural=peak {name '${name|def:}${ele_in_m}' } [0x6616 resolution 24]

Hi Carlos,

it seems that the Garmin software is interpreting a value with the prefix "\u001f"
to format it as something lije ", " + convertFeetToWantedUnit(value).

BTW: I found some routines im mkgmap which treat these prefixes special, e.g.
Label.stripGarminCodes(String s), but those are called for lines, not for POI, .
Maybe that is an error?

Gerd

Current rule for peaks using height: filter results in peaks named in
the form "name, ele m" (of ft according to your settings). I would like
show peaks formated as "name (ele m)". I've been playing with line "s =
"\u001f" + s;" in HeightFilter.java adding parenthesis in different
ways, but nothing worked as desired. Is there a way to get what I want?

But maybe an option to configure the output format of the height and conv functions (w.r.t. decimal separator, thousands separator, number of digits etc) might be useful? Perhaps the program could take (some of) the settings from the user's current locale.
