Updating Cycle data

To update the cycle path data in the applicaiton

1. Download british_isles.osm.pbf from Geofabrik. ~400MB

2. Get Osmosis - a tool for parsing open map data.

3. Run the script 'ExtracBikes.sh' To cut down the large pbf binary file into XML files containg just cycle data. Takes aprox 1 hour.

4. Set TEST_COREDATA to true in the config.h file:

    #define TEST_COREDATA               TRUE
   

5. Run the app in the simulator. Takes aprox 1 hour.

6. Copy the generated LBCoreData.sqlite file from the Simulator's documents folder to the bundle and change TEST_COREDATA back to false.

TODO

• Find a faster method of fatching paths from core data, try...

  • Use better hashing.
  • Split request into many subrequests. Update on the fly
  • Split up database.
  • Find a better way to store the data.

• Remore theb magnifinign glass icon or replace with text, e.g. "Zoom in to see more paths". Some users thought it was a button.

• Implement a system to update cycle path databse from S3.
