Contracted objective:

“To make data available to the public”


Contracted objective:

“To make data available to the public”

Open to interpretation:

What is “data”?

Who is the “public”?

How should it be made available?

National & global trends in data provision



What is “data”?

Maps spreadsheets reports

raw binary files samples photographs

GIS layers videos

etc...



Who is the “public”?

Interested & expert parties - local/national govt, NGO, iwi, ...

general public- tourists, recreational users, anyone, ...


How should it be made available?

Internet & direct contact(volume/complexity/format)

Online catalogue(metadata system describing content)

Web site(web mapping)

Simple web services(OGC WMS/WFS)


Trends:

USA: www.data.gov

EU: INSPIRE

NZ: data.govt.nzeGIF

public access to government data increasingly available via common standards & protocols

http://www.data.gov/


Web site architectural goals:

Reuseable (components & tools built for thisapplication can be used elsewhere)

Interoperable (use common standards/protocols)

Expandable (new surveys can be added & new datasets & map layers for a survey)

Redeployable (portal can be moved & runas an appliance)


Fundamental approach:

ABSTRACTION

data managed in scattered/remote databases(by appropriate experts)

data accessed & supplied centrally (few points of access)

simple web portal kept separate from data sources

data sources reuseable



ABSTRACTION

Software:

OpenLayers (embedded client)Spatial DBMS:Postgis/ArcServerPhoto DB: AtlasMetadata: Bluenet MEST (Geonetwork)

These are mostly free & Open Source applications(Note: Atlas & ArcServer are proprietary)

All software developed to integrate these in the portalare also free & Open Source


Metadata:

“data about data”

provides a searchable list of records describing datasets

provides information on fitness for use, contacts,descriptions, etc

provides access to actual data (eg: URL)


Metadata:

Geonetwork-

Open Source metadata catalogue from FAOGlobal & growing useStandards based

(ISO profiles/OGC protocols)

Bluenet MEST

ANZLIC fork of Geonetwork from AustraliaANZLIC & MCP profile support


Metadata:

Bluenet MEST

Customised by NIWA to meet OS20/20 BoI needs

Searchable access to datasets (maps/reports/etc)(contact details for off line datasets)

Access directly:

http://www.


Portal:

Standalone gateway to all content

Silverstripe CMS with custom web mapping module

Information on the survey & methods

Web mapping engine by survey method

OGC based data delivery - reuseable


Photos:

Public access via Atlas (digital asset management, used by NIWA)

11,000+ high resolution seabed and specimen photographs

Videos:

From fixed and towed cameras

Volume issue – available but offline


Quick demonstrations:

Main portal:General information & web mapping

Metadata portal:Search/find/download datasets

Photo database:Search/find/download photographs
