Maps on IPFS - IPFS Mapping Notes from 2016-07-03

[jbenet]

(cc @davidar - super relevant. i want to introduce you two to each other, and help out in shared efforts)

• @mikolalysenko and i met up to discuss mapping on IPFS and some efforts.
• We went over some of the stuff done so far (like @davidar's tile mapping)
• OpenStreetMap ipfs-inactive/archives#11
• OpenStreetMap Viewer apps#25
• @mikolalysenko will be working on this stuff in the coming weeks.
  • @davidar it's highly relevant to your interests, maybe work on stuff together?
  • we could setup a sync discussion later this week if relevant
• @davidar @nicola @mildred relevant for IPLD:
  • example constructions on IPLD
  • possibly some example cases for transformations
  • possibly IPLD selector stuff (to pull out the subgraphs fast!)
• @diasdavid @dignifiedquire -- all this is relevant to js-ipfs too

Notes from a discussion on 2016-07-03

Efforts

Map basics (much of this @davidar has done)

• basic importing of tiles
• having of all tiles at all zoom levels
• combining tile sets?
• layering of POIs and objects
• viewers in js able to explore maps

Datastructures

• make sure it's a proper persistent datastructure
• transform input files into an IPLD hypercube? (or whatever is used)
• versioning model (commits?) and tooling
• all sorts of routing things
• encoding some tiles as computation? rendering client side?

Features:

• routing queries
  • directions to/from
    • walking
    • driving
    • pub/trans (real time?)
  • solving problems (eg traveling salesman)
• geocoding (forward and reverse)
  • better geocoding (ask questions like "is this in the ocean?")
• REPL (geojs)
• tile rendering

DEMOS \o/

• 0. showing rendered tiles on a viewer on ipfs
  • https://ipfs.io/ipfs/QmNfwFPQqJARCQz87i1V3uAEF2t6WxAffTfA678Ad1JZiv/?/ipfs/QmUefFZttPf9xq4KTkk94rBbZEVrBsTreDi4JA8KYhQFX6
• 1. tuning this and making it perform well.
     target: world map with smooth zoom out and in
     (get closer to perf in OSM or gmaps, some fraction)
• 2. viewer with version history on map (slider timeline?)
• 3. geocoding:
  • enter address, see a point on the map
  • click a point, get nearest address
    (doesn't have to be perfect, we can import some known dataset)
• 4. map interactions (like get arc measurements, etc)
• 5. Routing 1! \o/
  • get routing directions from one point to another
• 6. Routing 2! solve routing probles
  • traveling salesman type problems
• 7. REPL for map? (GeoLISP! GeoJS! \o/)
• 8. write a tile renderer (store computation on graph itself, etc)
• 9. Pub/trans real time visualization
• 10. 3D map rendering

[davidar]

1. tuning this and making it perform well. target: world map with smooth zoom out and in (get closer to perf in OSM or gmaps, some fraction)

This should be resolved by upgrading to a recent version of mapbox-gl-js, currently blocked on osm2vectortiles/osm2vectortiles#326

3. geocoding

cf ipfs-inactive/archives#8

encoding some tiles as computation? rendering client side?
8) write a tile renderer (store computation on graph itself, etc)

Not sure what you mean by this? Rendering is already performed client side, only vector tiles are stored on ipfs

10. 3D map rendering

There appears to be an error in that version of the map. Here's a working version:

http://ipfs.io/ipfs/QmSszskauNW84RVSjuKwKhi1uv8xkgDG2dUiaWEZaMM21S/?/ipfs/QmUefFZttPf9xq4KTkk94rBbZEVrBsTreDi4JA8KYhQFX6

It makes me a little giddy that I can see an error in a web page, correct it, and republish it.

@Ghoughpteighbteau Fixed, thanks :)

[ryan-foamspace]

Really exciting stuff! Has there been any development on this recently?

[lidel]

seems to be continued in https://github.com/ipfs/ipfs/issues/233 :)

@Ghoughpteighbteau Hi,
Can you share the source of the map you have shared? I am curious how you have searched data based on location on IPFS.
