Hi
I would like some opinions please from those that make maps.
If you have a style that say sets the name of every path to 'Path'
eg: highway=path | highway=footway | highway=track {name 'Path' }
or anything similar that results in thousands of roads with the same
name, then mkgmap appears to freeze.
The code that is slow is creating a list of roads that will be used
when you search for an address in MapSource or on the device.
I can fix this in various ways, but I want to ask how useful it is to
have thousands of roads with the same name appear as a result of a
search?
For a start in mapsource, you only see a few of the results anyway.
Should I drop the name completely from the index when there are more
than say 500 roads with the same name in the same city?
There is a branch called simplify-sorted-roads where I am trying out
different approaches to the problem, if anyone else wants to try it out
or look at it.
I think it would be better to control it via style-file. Eg. you should
add a tagg like mkgmap:nomerge=yes for such ways.
