I’ve read recently in some forum post that you couldn’t select all ways in Kosmos and render them, even if they have no tags at all. Well, this evening I implemented support for this in Maperitive:

Maperitive wireframe

The white-ish lines represent OSM ways. The green color depicts OSM areas. The rules for this are quite simple:

features
    lines
        all lines : 
    areas
        all areas : 

properties
    map-background-color : #181818

rules
    rulefor : all areas
        define
            fill-color : green
            fill-opacity : 0.1
        draw : fill

    rulefor : all lines
        define
            line-color : lightgray
            line-width : 1
        draw : line

Anyway, I’m still hoping I’ll be able to fix all the “todo” stuff from my list within few weeks, but I cannot promise. It seems that for each item I remove from the list, two new items appear. I guess I’m another victim of the Ninety-ninety rule.
