So, OpenStreetMap

OpenStreetMap is AMAZING

OSM is a phenomenal phenomena Humanitarian Mapping efforts

But we need that basemap, and we need mappers

Communities are the entry point for Openstreetmap.

Communities get us mapping.

Communities keep us mapping.

Communities encourage better mapping.

Communities are made of individuals with Individual goals.

Most contributors belong to a category of ‘hit and run mappers.’

○ Initially curious, immediately overwhelmed

○ Initially curious, immediately overwhelmed

( mapping the world is hard )

○ Initially curious, immediately overwhelmed

○Only response mappers

○ Initially curious, immediately overwhelmed

○Only response mappers○ Communities meet infrequently

OSM Analytics can help us understand the barriers and reduce them!

How do we pull down live OSM contributions and keep their community identity?

Planet Streamhttps://github.com/developmentseed/planet-stream

The building blocks: CHANGESETS

Ingredient One: PLANET.OSM.ORG

Ingredient Two:OVERPASS API - Augmented Diff

Cook for a minute and…...

PLANET STREAM

1. Put ingredients into a basket

2. Match up items in the basket by id

3. If match, combine them to make RICH CHANGESETS

4. Take the rich changesets and push

them through worker code to derive statistics.

Rejoyce!

By using workers on the rich changesets we generate:- User & Hashtag

Statistics- Trending Hashtags- Live map data

○ Initially curious, immediately overwhelmed

○Only response mappers

○ Communities meet infrequently

○Hard to identify potential super users

Planet Stream will work with any #,

...but does require setup

Caveat:This system is dependent on Overpass, which can hiccup.
