[mkgmap-dev] RAM and mdr Europa ?

Tue Mar 28 11:40:40 BST 2017

Hi

On my device: find > "All POI" (or any of the more specific finds) only
show certain types - 0x12, 0x1c, 0x1d, 0x29 - 0x30, 0x64 - 0x66.

If the POI doesn't have a name, it shows as "Unnamed xxx" where xxx
seems to be supplied by the garmin device depending on the type/subtype

The default style has the following:

barrier=bollard | barrier=bus_trap | barrier=gate [0x660f resolution
24]
barrier=block | barrier=cycle_barrier | barrier=stile |
barrier=kissing_gate [0x660f resolution 24]

0x660f on my device is "Land Feature"/"Pillar"

So, when out walking and I want to see what is nearby, doing a
find>"All POI" can yield a long list of "Unnamed Pillar" because of all
the nearby gates and stiles.

I never want to search for a barrier, but would like to see them on the
map, so using a POI type that doesn't show on find> and setting the
name of the POI to the type of barrier solves this.

Likewise, I like to see linear barriers, so in my style/lines I have:
barrier=wall | barrier=fence | barrier=hedge | barrier=ditch
  {add name='${barrier|subst:"_=> "}'} [0x2a resolution 24]

#RWB is just an marker I use so I can tell which are my changes from
the default style when I want to merge in release changes.

It occurred to me later: is there a set of POI types that are never
searchable on any device. If so, can they be omitted from the POI
index, so saving mkgmap index processing memory and IMG size
