[mkgmap-dev] Questions related to practical usage of MKGMAPFrom Garvan g.okeeffe at online.com.kh on Wed Jul 1 13:40:09 BST 2009
Hi. I have a few questions related to MKGMAP that I could not find answers to in the archives. My data source is mostly OpenStreetmap, but I used gpsmapedit for editing and adding my own traces, so I am using mp format files with the compiler. I am open to other suggestions on managing data, but I need strong editing capabilities. Q1. I have about sixty roads where I get the severe warning: SEVERE (RouteArc): Way ~212 contains an arc whose length is too big to be encoded so the road will not be routable As the warning gives no line number, I am at a loss to find the problem. Does anybody know how I might locate these 60 roads? I tried sorting the roads by number of points, but did not seem to find a match. Perhaps if I calculated the length of each road segment, and sorted by length? Q2. In encoding sea polygons, I must split the polygons up so that they have less than 256 points (I did this in gpsmapedit). When zooming in and out, sometimes polygons show white lines in between, where the shape has been optimized. It there a way to avoid this, or a better way to split up large polygons? Is there a utility to help with this problem? I would only need to do it once, so it does not matter if it is a convoluted route to what I want. Q3. I would like to use road numbers as labels. In gpsmapedit you use the a code like this ~[0X06]117 in the label for the road, but this did not work in MKGMAP. Is there some other way to display road numbers? Thanks for any help and suggestions.
