Offline navigation - GraphHopper - preparation

perfect, this is what I hoped to hear. I've tested new version of GH just on couch, but hope that improvements made mainly by @karussell will be useful in the field!

I wonder: might it be possible when you have time that you create a generator for the 0.2.0 add-on as you did for addon_0.1.7? I found it useful recently for creating an up-to-date england.osm-gh routing file, for example, and I imagine it might be useful, too, for those who desire an area not contained in 2015.09.19 - v0.5.

Thank you.. new version work perfectly! Use it 10 times a week. Dont like the geeky BRouter..

Each product has its customers, none is intended to serve all , whatever product domain is considered.

For off-line car navigation, GH is definitely a good choice.

For bicycle and foot navigation, one can have with GH any ice cream flavour whatever one wants, if it is vanilla. Nothing bad with vanilla. For other flavours, there is the Brouter.

Hi guys,

new version of add-on GraphHopper - 0.1.7

Requirements: Locus Map 3.9.3.3+

Download from HERE data/GH addon 'version' - based Y.apk and install.

Download from HERE 'date' - Y/your country/*-gh.zip routing file

It seems the names and the contents of Google drive subfolders is switched. The apk is in data folder, while data are in apk folder.

I visited your Wiki... You certainly got me curious! Bookmarked..
I just don't think Brouter is very well integrated in Locus, but that's a personal experience. Gave GH a go when I found this thread and got stuck in old habbits.
I don't do alps or off-piste skiing, mainly hiking on known trails towards next geocache container..

Would it make sense to ask menion to allow Locus to choose different routing engines according to travel mode?
I would like to choose GraphHopper for car travel and BRouter for travel by foot.

It was already explicitly asked as the idea in Help desk.

Is this the suggestion that you refer to: http://help.locusmap.eu/topic/independent-configuration-of-navigation-services-for-carbikefoot ?
I found the suggestion hard to track down on the help desk!

Menion · November 12, 2015, 17:08:10

creating own routing data - pack with generator added. Anyway suggest to read "how to" on pages of graphhopper

separating profiles - don't talk me about this. I think on it for last few years always when I wants to use Locus on bike, when it was previously used in car

.

Each red traffic light should give some minutes to fix this and expand Locus feature :-)

The help looks like a candy, Yes., that one,. Also closely related
http://help.locusmap.eu/topic/short-fast-pedestrian-navigation-modes-fro-brouter-navigation
http://help.locusmap.eu/topic/global-settings-profiles-for-navigationguidance-settings

Personally, I quite like the OSMand approach. Anytime aOSMAnd user enters the part of configuration related to navigation, he is asked for the context ( car / bike / foot ).

Interesting is this note on GraphHopper Github page,
what means similar limitations for proper car navigation, as Brouter admits:

"Please note that currently none of the vehicles accounts for turn restrictions."

https://github.com/graphhopper/directions-api/blob/master/supported-vehicle-profiles.md

john_percy · November 13, 2015, 08:32:15

That refers to the GraphHopper Maps web engine which runs in speed-up mode.
GraphHopper itself includes the possibility of turn costs and turn restrictions but requires turn costs to be turned on:

QuoteThe turn restriction (also turn cost) feature is currently not implemented for the speed-up-mode, and this speed-up-mode is used in GraphHopper Maps. But you can enable the flexibility mode in the config.properties and it will work

In the graphs I use which I prepare using Atlas, turn costs are on for car routes and off for bike or foot. As far as I can tell, the same is true for the graphs menion has prepared and made available (though I only checked Gibraltar).
