thoughts on roadmap - start with Delaware

Improve Delaware OSM

Let’s get Delaware OSM improver running first, because:

• it’s useful
• focuses dev efforts on product/launch
• tees up further work

  Launch Requirements

• front-end
  • two react views, fed by Django
  • list view of potential OSM errors
  • click in list view to show details for an error (a map view and a button to goto OSM to edit)
• analysis - quick and dirty (use what we got)
  • train a brain with the current tech
  • more or less already done
  • run it on AWS and save the results (all of Delaware, all 4 bands, run the conv net option)
  • output predictions from brain for all test data, put in Postgres/django
  • UI shows these in order of confidence
  • database props:
    • ne_lat
    • ne_lon
    • sw_lat
    • sw_lon
    • grid_x (redundant with the lat/long but meh, data exists in tiles so stick in PG for now)
    • grid_y (ditto)
    • source_naip
    • percent_on
    • state (always delaware now)
  • attach lat/long to each prediction (using existing code)
  • this data drives the UI for deeposm.org/state/delaware
• django back-end
  • login/signup user tables
  • thumbsdown votes on edits we suggest v1? maybe punt this too?

    Punt for now?

• need the following for scale, but not Delaware, punt?
  • naips in Postgres
  • OSM data via Overpass
• better neural net
  • could do a relu + conv to be slightly better, or even deeper
  • see how good our current brain works, ~86%, in the delaware scenario
  • deeper it is, the longer the training and slower the iteration
  • need to look at paper to see how much computation another ~4% costs us

    Other Doable Product Ideas

• other states
  • might as well scope to one state for now
• produce a geojson overlay to send over when they edit on iD
  • improvement on the tools for editing OSM
  • idea is to keep iterating on the tools unti it’s automated
• other features like tennis courts
  • this might be a cool next move
  • might be easier and quickly useful to generate the “best tennis court search”
• provide training data as a service
  • also: provide hosted jupyter + training data as a service
  • unclear how people want this packaged?
  • serve ourselves first?
• let people upload and classify drone imagery
  • would need production style data pipeline
  • would need more work on analysis
  • one of the harder product ideas

@zain @silberman Here are some thoughts on how to roadmap this... roadmap runs through Delaware and onwards?
