Look at the filesizes of the routerdb's.

[xivk]

Try to decrease the storage space needed to store a routerdb. Filesize has increased in v1.1 using the new contraction method.

There is some 'low hanging fruit':

• [x] Look at the strings (roadnames, tags, etc...)
• [x] Look at geometry simplifcations.
• [ ] Look at implementing a diff encoding system for the geometry of edges. Some inspiration:
  • https://developers.google.com/maps/documentation/utilities/polylinealgorithm
  • https://github.com/bertt/PolylineEncoder.Net
• [x] Is everything being properly compressed.
• [ ] Optimize restrictions db's.
• [x] Look at vertex simplifications.
• [ ] Remove vertices that have no edges (WARNING: this will change vertex id's, do this at the right time)

Other things to look at:

• [ ] Evaluate the core Network object and storage.
• [ ] Do the same for the contracted graphs.

Closing this, working on Itinero 2.0 now, where this will be covered.
