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...

uploading, sharing, and workingwith 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 webenvironment for

geospatial content

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

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 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.

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

actually do

SDI

GISGIS

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...?)

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.

We haveeven more ambitiousplans for GeoNode

moving forward

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

04/26/10

Groups Matter

04/26/10

Organizations will have a presence

Allows organizationalendorsement of data

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
