Spatial Data Infrastructure (SDI)
“[Spatial Data Infrastructure] provides a basis for spatial data discovery, evaluation, and application for users and providers
within all levels of government, the commercial sector, the non-profit sector, academia and by citizens in general.”
– SDI Cookbook
Spatial Data Infrastructure (SDI)
The theory of SDIdeveloped before
we learned what waspossible with the Internet
...what an ideal SDI would be like
Imagine...
...an SDI that makesuploading, sharing, and working
with dataas easy as blogging
Imagine...
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 puts 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
Tom, a GIS analyst doing research, seeks out correlations between health and bicycle routes
Federated search
Tom searches for data in a single federated index and downloads the data as a batch.
Vision
Theory
How do you make an SDIthat's as compelling
as modern, widely-used web services?
Make an SDI using the best practices of these web services and projects
General Principles
Grow Bottom Up Align Incentives through Openness Build it for Casual Users Features, not Policies
04/26/10
Grow Bottom-Up
Reduce barriers to participation as much as possible.
Be useful (if imperfect)as fast as possible.
04/26/10
Grow Bottom-Up
Start with data.Let users work with it.
Generate metadata as needed.
Align Incentives...
Align incentivesfor contribution and use
so growth is natural.
Align Incentives...
Reward data providers for good contributions
Encourage users to contribute back Make value of service transparent to system
providers
... through Openness
Provide a reason to participate Reward collaboration Make it as transparent as possible
Build it for Casual Users
UsingSpatial Data Infrastructure
should not require expertise
Build it for Casual Users
Reading documentationis too much work.
The burden is on the system developersto make it intuitive to use.
Features, not Policies
If SDI technology requiresNo
overhead or compromisesthere will be
Noorganizational resistance
Features, not Policies
Look for and implementsmart technical solutions
tolegitimate organizational concerns.

Founders
Want GeoNode fordisaster reduction
Global Facility for Disaster Reduction and Recovery (GFDRR) and World Bank
UN International Strategy for Disaster Reduction (UNISDR)
Builders
Not-for-profit social enterprise Builds and supports open source geospatial software Aims to build the Open Geospatial Web
GeoNode is open source.
Install it for free.
Contact the developers directly.
Collaborate with us and each other.
Build local capacity and be independent of any vendor.
We will soon release
GeoNode 1.0

What doesGeoNode
actually do
?
Give a reason to participate
A major problem with SDIis that people
lack incentives to use it
Problems with Portals
No benefit to registering Few real users No recognition or reward for the effort Uses stick, not carrot

SDI
Embed SDIin the real work ofGIS practitioners,
and 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 forman web to be browsed
Generic search engines(like Google, Bing)
can crawl and rank these pages.
Users Have Identity
People fill out user profiles to establish identity on the web
Profiles are also useful data
Meanwhile, 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 publishedwith open standard
CSWusing 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
Deep data security extends to OGC services
We are building GeoNodeto accommodate
any institution's access policy
All these features are included inthe current 1.0 release candidate.

We haveeven more ambitiousplans for GeoNode
moving forward
The partnership investing in GeoNode is growing
The roadmap expandswith the vision and needs
of its partners
Use the Social Network
The Social for Search
04/26/10
04/26/10
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

Organizations will have a presence

What about INSPIRE?
GeoServer needs WMS 1.3 to meet INSPIRE standards
OpenGeo has found partners to fund this development
It is coming soon
Open Data Skepticism
Isn't GeoNode an open data platform?
Doesn't open data raise concerns aboutdata quality and data security?
Open Data Optimism
Yes, GeoNode is designed to promote open data.
Open Data Optimism
Features likeUser reputation
Organizational endorsementFlexible security
address data quality concerns
Open Data Optimism
GeoNode supports
the continuum
of openness with a common platformfor institutional GIS and neogeography
What about Features X,Y,Z?
We welcome yourinvestment
in new GeoNode featuresand
involvementin the developer community.
