[GraphHopper] Suggestions for an OSM solution

[Markware Software Services]

Hi Vincent, Sounds to me that the best apporach, if your maps are static is
a simple tile server running on your plug computer and use that, or another
one to run graphhopper to do the routing. That will be determined by the
size of your map and routing area and what memory you have available on the
server. By the looks of it they are quite cheap so I would probably use
two, then you have some server redundancy. Set up he tiles and graphhopper
on both, but use one on each, switch to one unit if the other goes down or
needs to be sent for updatng, etc.

Serving premade tiles from a small linux computer is quite feasible, make
the tiles on another system and dump them on the plug computer. I use
GeoWebCache like this, but there are several others proxy style Tile
Servers.

Have a read of https://wiki.openstreetmap.org/wiki/Creating_your_own_tiles

I use OpenLayers for the Client side work, again there are a couple of
other options like Leaflet, which Peter uses so your Client solution might
be quick to deploy if you just use his demos and drop your own graph in.

You can build your Graphhopper graphs off line and then download them to
the plug computer and route on your local lan over the tiles served form
the tile Server.

All quite feasible

Cheers
Mark
