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 SDI developed before we learned what was possible with the Internet

...what an ideal SDI would be like Imagine...

uploading, sharing, and working with spatial data as easily 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

An easy, collaborative web environment for geospatial content

Theory

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 Grow Bottom Up Align Incentives through Openness Build it for Casual Users Features, not Policies

04/26/10 Grow Bottom-Up Start with data. Let users work with it. Generate metadata as needed.

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 Reading documentation is too much work. The burden is on the system developers to make it intuitive to use.

Features, not Policies If SDI technology requires No overhead or compromises there will be No organizational resistance

Features, not Policies Look for and implement smart technical solutions to legitimate organizational concerns.

is a new software project to build this SDI

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. Users can be independent of any vendor.

Partners Australia-Indonesia Facility for Disaster Reduction (AIFDR) Global Earthquake Model (GEM) Secretariat of the Pacific Community (SPC)...and others

We will soon release GeoNode 1.1-beta

Vision Theory Context

What does GeoNode actually do ?

GIS SDI

GIS SDI

Embed SDI in the real work of GIS 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 form an 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 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

GeoNode's components interact through clean API's Others can build apps around GeoNode Or swap out components (Drupal...?)

Let Users Control Content

Content owners control access with easy user interface Deep data security extends to OGC services

We are building GeoNode to accommodate any institution's access policy

All these features are included in the current 1.0 release.

Extensions

Vision Theory Context Reality

Future

We have even more ambitious plans for GeoNode moving forward

Use the Social Network

The Social for Search

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

04/26/10 Groups Matter

04/26/10

Organizations will have a presence Allows organizational endorsement of data

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
