Re: [mkgmap-dev] Idea: map layers (multiple output tiles per input tile)

2011/4/9 Marko Mäkelä marko.mak...@iki.fi: Maybe I was being unclear. The use case that I have in mind is the generation of a map set that comprises several layers (families in Garmin terminology). These layers can be enabled or disabled in the map settings menu on the GPS receiver.

Same here. My only issue with QLandkarteGT is the inability to plan routes. Again, the old way of doing things would not be going away. This multi-layer stuff would remain compatible with existing styles and scripts. To take advantage of it, you would have to edit the styles and scripts.

[mkgmap-dev] Can Extra Resolutions be Implemented

2011-04-10 Thread Bill Lancashire
It is clear when zooming in on my GPSMAP 62s that Garmin can make use of resolutions greater than 24 with regard to 'styling': I have a map in which I go with the default 'styling' for 'Residential Roads (0x06)' by not specifying this in my TYP file. I zoom-in to the point where I know that

Moin, since my GPS-maps rely heavily on multiple layers, there would be some benefit, if producing of these layer could happen within a single mkgmap run, so that the common proccesing steps would be executed only once. Whether this can be achieved, depends on the time of the processing step. I

Marko, I like the idea to use the same tile data in one mkgmap run to create multiple img files. At least it is worth to discuss it, if it makes mkgmap faster. Before starting to implement it some things have to be considered: * The advantage to create multiple img files in one mkgmap run is

[mkgmap-dev] [PATCH v1] Avoid needless multipolygon handling

2011-04-10 Thread WanMil
The patch (based on an idea of Marko) checks if a multipolygon and its potential outer members has tags that are defined in the style. If not the multipolygon processing is not performed. This reduces processing time for small styles with a limited set of tags. The effect is not as big as
