Spatial Data Infrastructure (SDI)
Spatial Data Infrastructure (SDI)
“…the sources, systems, network linkages, standards, and
institutional issues involved in delivering spatially-related
data from many different sources to the widest possible group
of potential users at affordable costs.”
– Groot & McLaughlin 2000
The theory of SDI
developed before
we learned what was
possible with the Internet
Imagine...
...what an ideal SDI would be like
Imagine...
...an SDI that makes
uploading, sharing, and working
with data
as easy as blogging
Publishing data
Anthony has some spatial data and wants to
display it as part of a blog post.
Publishing data
Anthony uploads it to a public SDI, styles it,
provides a background, and then a map widget
on his blog.
Publishing data
Meanwhile, the data, style, and map remain
available on the public SDI
for others to use.
Metadata and reputation
The World Organization tells Cameron, their
consultant, to put data she has gathered on their
SDI.
Metadata and reputation
Other users notice mistakes in the metadata.
They notify Cameron and give it a low rating.
Metadata and reputation
Cameron fixes the mistakes, and the other users
rate the data more highly. Her reputation on the
SDI improves.
Federated search
A regional Health agency and a regional Transit
agency have separate SDI systems.
Federated search
Phillip, a GIS analyst doing research, seeks out
correlations between health and bicycle routes
Federated search
Phillip searches for data in a single federated
index and downloads the data as a batch.
How do you make an SDI
that's as compelling
as modern, widely-used web services?
Make an SDI using the best practices of these
web services and projects
General Principles




Build Bottom Up
Align Incentives
Be Open
Non expert use
“Bottom-up SDI”
Start with data.
Let users work with it.
Generate metadata as needed.

“Bottom-up SDI”
Reduce barriers to participation as much as
possible.
04/26/10
Align Incentives
Align incentives
for contribution and use
so that it
develops naturally
Be Open
•
•
•
Give users a reason to participate in the
system
Reward collaboration with recognition and
harvest the results
Make as much information transparent for
others to use as possible.
Non-expert User
You shouldn't have to be a GIS expert
to use your SDI
There's so much more
These principles just scratch the surface of the
qualities the next generation of SDI should have.
But can it be?
These are nice dreams. But will they ever be a
reality?
is a new software project
to build this SDI
It's open source. Of course.
Founders
Founders are interested in GeoNode primarily for
disaster risk management
 Global Facility for Disaster Reduction and
Recovery (GFDRR) and World Bank
 UN International Strategy for Disaster
Reduction (UNISDR)
That's the vision and the context.
What have we actually built?
Which
best practices?
How does GeoNode
implement them?
Give a reason to participate
A major problem with SDI
is that too few people have
an incentive to use it
Problems with Portals




No benefit to registering
Few real users
No recognition or reward for the effort
Uses stick, not carrot

Embed SDI
in the real work of
GIS practitioners,
it will have more impact.



Provides styling and cartography tools
Users can use the tools on data they upload
GeoNode provides a reason to participate



Map composer makes Maps
Maps are an important content type
They bind together ecosystem of geospatial
content
Maps, Data and Users form
an ecosystem to be browsed
Users Have Identity


People like to fill user profiles to establish
identity on the web
Profiles then become useful data
Metadata pain
Good metadata for geospatial data is important
but hard to produce.


GeoNode has user profiles and features them
prominently
Those profiles have ISO metadata fields
within them
Metadata Made Easy
Metadata Published
Metadata is published
with open standard
CSW
using GeoNetwork
Open standards and API's


Data published by GeoServer in OGC Services:
WMS, WFS, WCS
Metadata published by GeoNetwork in CSW
KML for Google
We use open standards for data access.
GeoNode also has open APIs
HTTP
HTTP
HTTP



GeoNode's components interact through
clean API's
Others can build apps around GeoNode
Or swap out components (Drupal...?)
Make Content Portable
Let Users Control Content


Content owners control access with easy user
interface
Data security extends to OGC services
All these features are included in
the current 1.0-beta release.
DEMO
They only scratch the surface.
GeoNode has a much more ambitious roadmap.
Use the Social Network
The Social for Search




Record statistics on usage
Let users comment on and rate content
Use that information to improve search
results
The Social for Quality


Ratings affect user reputation
Will encourage quality content on SDI
Groups Matter
04/26/10
04/26/10
Organizations will have a presence
Allows organizational
endorsement of data
Big Plans
These features,
based on the best practices of the web,
will likely be developed within a year
Even Bigger Plans
There are also features specific to
Spatial Data Infrastructure
on our roadmap

What about INSPIRE?


GeoServer needs WMS 1.3 and WFS 2.0 for
GeoNode to meet INSPIRE standards
OpenGeo is looking for partners to fund this
development
Open Data Skepticism
Isn't GeoNode an open data platform?
Doesn't open data raise concerns about
data quality and data security?
Open Data Optimism
Yes, GeoNode is designed to promote open data.
Open Data Optimism
Features like
User reputation
Organizational endorsement
Flexible security
address data quality concerns
Open Data Optimism
GeoNode supports
the continuum
of openness with a common platform
for institutional GIS and neogeography
What about Features X,Y, Z?
