Business model Rockestate
● Open geospatial data is often needed in data science use cases
● Gathering, cleaning, standardizing this open geo data is hard work
● Data scientists are too scarce to do this internally

4.
Business model Rockestate
By doing lots of use cases
● We improve our curated data lake
● We gather background knowledge about Machine Learning, spatial
statistics and building products in general

Feature extraction from GIS applications
Open geo data?

i.e. addresses
● Old school: sell your own address database
● New school: work and contribute to an address database that is
shared by all stakeholders

Do we give back?
Everything open source
It is not because you open
source something, that it helps
the community
We do have some secret
sauces that we can’t just open
today
Everything closed source
Doesn’t work, clients love
transparency
Is not attractive to attract
talent

14.
Do we give back?
● We blog in great detail
● We give trainings to non-profits
● We tried to organise a hackathon for a good cause
● We contribute to open source geo software
● We speak at meetups and open source events

15.
Why Open Knowledge?
● Measuring my weight daily allows me
to monitor my behaviour
● We believe these transparent
dashboards are needed to evaluate
policy
● i.e. dashboard about traffic accidents
● i.e. remuneration of notaries
