Spatial Data Infrastructure Best Practices with GeoNodePresentation Transcript
Spatial Data Infrastructure Best Practices With Sebastian Benthall + Galen Evans OpenGeo World Bank
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 Spatial Data Infrastructure (SDI)
The theory of SDI developed before we learned what was possible with the Internet
...what an ideal SDI would be like Imagine...
...an SDI that makes uploading, sharing, and working with data as 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 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
Build Bottom Up
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.
Align Incentives Align incentives for contribution and use so that it develops naturally
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 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.
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
Organizations will have a presence Allows organizational endorsement of data
These features, based on the best practices of the web, will likely be developed within a year Big Plans
There are also features specific to Spatial Data Infrastructure on our roadmap Even Bigger Plans

Today, Sept 9 14:00, right after lunch Room 4 “ GeoNode Architecture” David Winslow
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
