[mkgmap-dev] Malformed piers and other issues

Hi Mira,

These piers are like 3m wide, it is at the limits of resolution for 
Garmin maps. There is no easy solution for this problems.

You can for example add piers as a polyline, this could show the missing 
ones.

Preserving shape could be improved a bit by preprocessing data, like for 
example simplification before rounding to Garmin resolution. Mkgmap 
probably doesn't make this kind of simplification.

These are proposed ways? They aren't routable. I think mkgmap doesn't 
preserve connection for non-routable polylines, which IMHO is a flow.

 > Same road are interupted in certain zoom level
This could be a problem with very short legs of a road or with 
non-continous type of the road. Difficult to guess.
