*What isVGI? VGI is short forVolunteered Geographic Information – a term coined by Michael Good-
child  to describe the creation of geographic data outside of professional routines. Examples for VGI
projects are OpenStreetMap or Google Map Maker. In our study, we concentrate on OpenStreetMap (OSM).
They found OSM interesting
enough to register.
Why did they not contribute?
To find out about barriers for contributing we
conducted an online survey in February 2013.
Here is who participated according to experience
level and gender:
I don‘t know
I know OSM,
but I never
I have an OSM
account, but I
I used to be
active, but I am
I am currently
active in OSM
These are the groups we asked about
barriers for not

Unfriendly or hostile communication.
Edits are not visible on the map.
I lost interest in the aims of OSM.
Help and support are insufficient/confusing.
Lack of communication/interaction with community members.
I am afraid to do something wrong.
In my work/project I don't need OSM anymore.
Editing is too complex.
I forgot about it.
Map seems complete in my area.
Contributing is too time consuming.
No significant differences between the three experience-groups were found.
The results also indicate no gender-related differences.
Many thanks to the OpenStreetMap
community and all participants of our

This study was kindly supported by the Austrian Ministry for Transport, Innovation
and Technology (BMVIT) within the research program FEMtech fFORTE.
Here are the weighted answers to what might
motivate them to contribute (again)
Improved help and support options
Positive feedback / rewards for editing
Mapping with other people, indoors
Mapping with other people, outdoors
A more user-friendly interface
Dedicated tutorial for beginners
Mapping for a
dedicated purpose(e.g. crisis mapping)
