I "played" a little bit with overpass-turbo and extracted all french departments (still a draft) to display "low_emission_zones" I found a similar discussion here, dealing with BRouter NoGo areas. But finally it's not the same. The "No go" areas deal with what the name says, defined zone where the BRouter algorithm should plan a bypass. Coming to Cruiser: Cruiser offers the possibility to import own pois and tracks. Can we have the same solution for polygon area overlays? And then to select the color and transparency? - that would be great. For a first test, I attached the data from the map above as gpx file (zipped) and as original Overpass-Turbo query content for copy/paste to reproduce request if needed. |

@DIrgi thanks for the suggestion. Overpass can export in GeoJSON format? Cruiser can display GeoJSON content, it's just not public yet, unless we need it. 🙂 |

Displaying polygon overlays is one thing. Store them like favorites / routes / tracks with adjustable properties, |

Next Cruiser will also import GeoJSON files:
We can rename "My collection | Tracks" to "Tracks / Areas" and store 2 overlay types:

I have a (slightly modified) Polyfile creator (using Leaflet) here for creating custom map areas, turns out that GeoJSON is also offered so I can conjure-up all sorts of fancy areas/zones where a simple radius may not be sufficient. For starters, the London Congestion Charge Zone: GeoJSON content: |

The fact that Android tightens the security restrictions from release to release is understandable on the one hand, but annoying on the other. The restrictions for external files may also become critical, but Import/Export will still have to exist. So external file handling has to be there anyway. But nevertheless to minimize the use of external files, the nogo areas in "My collection" - okay! All "My collection" items are handled globally, thus all nogo-areas would then be applied in all profiles. That's sub optimal. I accept the objection that this idea increases the complexity of Cruiser. But the topic of nogo areas has already been placed in the "Advanced" section. And we can see what leveling down to mediocrity feels like at K3 ... |

Please do not set many and complex polygons as no-go areas. This can significantly slow down the route calculation. |

Import GeoJSON points, lines, polygons in favorites is available in #641
"Closed" GPX tracks / routes can also be imported as polygons
Polygons can be used as no-go areas in route planning
