Help with offline geocoding/navigation with geojson

[GoogleCodeExporter]

Hi,

This is not an issue.
I need a help/hints for working with offline maps.

The application is using offline map from mbtiles created using MOBAC for a 
small area.I have the geojson files with POIs and waypoints. which is rendered 
nicely using osmbonuspack in the app.
Now i need some kind of ability provide navigation within the area.

any help is much appreciated.

Thanks,
Safeer

Could you explain a little bit more what you want?

basically I'm working with an offline map application.
I'm looking for a solution to do offline navigation from a geojson data.

Could you explain clearly what you mean with: 
"Now i need some kind of ability provide navigation within the area."

Hi,

Sorry for that.
Let me try explain,

Im working on an android application with offline maps for a small area like 
private resort/golf course. The details of the area is not available in OSM(not 
public).
So i have created the data using JOSM(but didn't upload to OSM) and saved it as 
geojson format.

For the tiles i have captured using MOBAC as mbtiles.

The map is rendering well using the mbtiles and geojson details.

I need to implement features search for POI, navigate to POI in this 
application.
But osmbonuspack is using external online apis for those things.

I need a api to search the geojson data for POIs and Navigation.

Hope you understand what i meant.

Thanks

OK, I understand. 

For POI search: I imagine that you have a very small amount of POI (if small 
area): is POI search really relevant? Anyway, implementing POI search yourself 
should be quite simple. 

For navigation: tricky. Maybe using GraphHopper? Not the online service, but 
the Android offline version. Look at GraphHopper site.

For the POI search, which of the following is good?
1. parse and search the geojson
2. convert the data(osm/geojson) into SQLite database and query.

or do you have any other suggestions?

Both will work. 

For 1) => geojson parsing to KML structure is already available with 
OSMBonusPack. You just have to search in a "KmlFolder" object. 

Both approaches are basic Java programming: if you feel this is complex, I'm 
afraid that the next step (navigation) may be unreacheable to you.
