## INTRO

SLIDE 1
OpenStreetMap: it only works in practice. In theory, it can never work.

An extremely open project, where in theory one person could destroy a huge amount of things. But data does not degrade, quite the contrary! It seems we're doing something right!

## Key data scope

SLIDE 2
Most spatial data is created for a specific purpose, and only for that purpose. > this limits re-use, even if it's open data
SLIDE 3
OSM is many people with many purposes, forced to work together.
> why map new things that nobody is using yet? Because it's fun!
Chicken & egg problem: usually solved by spending money, with a solution fit for just the purpose. Solved by OSM by "slow roll", ever widening scope.

Sudden game-changes as the data matures:
- suddenly we're the best for cycling
- suddenly we're the best for a basemap
-> better to jump on the train a little early, rather than a little late >> that's why Facebook or TomTom are investing significantly in OSM

Use
- Since the data is freely avalaible, you can use it for any usecase
- Since many of the tools are open source, it can be significantly cheaper to use

## Examples

SLIDE 3 - anyways

* road planning impacts, to human measure ("twinned routing" > current / post route plan change)
http://gent-circulatieplan-new.anyways.eu/?view=3.7050971,51.0487434,13.38&o=3.6957050,51.0473600&d=3.7249270,51.0518000
Examples:
- routing to guide people to more "community friendly" routes (example www.slimnaarantwerpen.be)

And further:
- OSM is in many cases the best routable network
- especially when it comes to pedestrian or cycling routing
- it's easy to extend the data with details for -for example- emergency vehicles

SLIDE
* landuse map from heidelgis
Turning OSM data into an analytical tool, filling in the blanks with inference or external data
https://osmlanduse.org/#13/8.68532/49.40363/0/

SLIDE
National institions are beginning to take interest
* statcan: building experience with OSM through mapping projects > building metadata
* Kosovo census might make extensive use of OpenStreetMap
* National mapping agencies & crowdsourcing: http://www.cs.nuim.ie/~pmooney/eurosdr2017/

SLIDE
* Example of mutual benefit coordination: Road Completion > using official data to improve OSM
- building trust in the OSM data: guaranteed minimum quality
- feedback look back to the official data source

Other topics:
SLIDE: watermap
* specific types of POIs can now be mapped without general mapping knowledge > tools like MapComplete and MapContrib make it really painless to make an editor
* https://water-map.org/
* topical mapping tools:

## Closing

Hi, I'm Joost, I'm with the OpenStreetMap Foundation - and with the Belgian organization - and working on the practice at least as much as the theory :)
The OSMF does not decide what happens in and with OSM! Therefor we cannot be a fully fledged project partner, but rather a facilitator. We can help bring the right people together

When evaluating possible data sources, don't forget to take our exponential growth in account
