Software - ProprietaryExamples•Erdas Imagine•ENVI•ArcGIS

Software - ProprietaryPros•Well supported in universities•Expected by employers•Tight integration with sensors (ENVI in particular)•Generic•Robust?

Software - ProprietaryCons•Requires dedicated machines (normally a lab)•Expensive•Black-box

Software - FOSSExamples•GRASS – The daddy of them all•Opticks•Q-GIS•U-DIG•Whitebox•SAGA•ILWIS•MapWindow•Etc.

Software - FOSSPros•Well supported by the community•Allows development on any machine• You can develop a portfolio of work that stays with you• Generally cross platform•Transparent processing• White box (VERY important)•Open processes are more in-line with CLOUD processing• Workflow orchestration•Robust•Extendable by individuals

Software - ProprietaryCons•Some interface issues•There is a perception that FOSS is not as good as proprietary•Bleeding edge 3d does not always compete with thecommercial

Software – Open Source Geospatial foundationOSGeo: http://www.osgeo.org/• To provide resources for foundation projects -• To promote freely available geodata• To promote the use of open source software in the geospatial industry (not just foundation software) - eg. PR, training, outreach.• To encourage the implementation of open standards and standards- based interoperability in foundation projects.• To provide support for the use of OSGeo software in education via curriculum development, outreach, and support.• To support use and contribution to foundation projects from the worldwide community through internationalization of software and community outreach.• To operate an annual OSGeo Conference,

Software – Open Source Geospatial foundationOSGeo: http://www.osgeo.org/• Live DVD: http://live.osgeo.org/ • A pre-configured XUBUNTU O/S with a range of applications installed and pre-configured (this is excellent  )• OSGeo4W: https://trac.osgeo.org/osgeo4w/ • A pre-compiled binary install of different OSGeo approved packages for windows.• Both the above deal with some of the more complex bindings between applications.

The Future – collaborative computing

Licences - Why are they an issue?Data is rarely in the „public domain‟• It is normally available under a licence.Licences dictate:• Who owns the data• How you can use data• How you reference the data• How you can share/redistribute the data (and any derivatives)LICENCES ARE REALLY IMPORTANT

Licences – examples: Commercial high resolutionsatelliteUnder a strict license that dictates:• Who can use the data (normally a single organisation)• Sometimes for how long• What happens with the derivativesThe license protects their data which protects their incomestreamA user does not „own‟ this data• They use it under licence

Licences – examples: GovernmentResearch satellitedataThe licences vary:• Military• Research grade• ArchiveMuch of this data is released to the academic community• Community science (?) initiatives • The collecting body does not have the resources to analyse the data • The collecting body captures data on behalf of a broad community• The data is no longer sensitive or relevantExamples: Landsat, ASTER, Corona

Licences – examples Landsat 8Australia will publish images captured by soon-to-launchsatellite Landsat 8 online, in close to real time, for free underthe Creative Commons Attribution 3.0 Australia licence.“We want to make as much data freely available as possible,”says Jeff Kingwell, the Section Leader of GA‟s National EarthObservation Group. “We will move towards a system wherewe are taking Landsat data in, in near real time.” Data will becorrected to make it usable, then published, all in as close toreal time as is practical.How COOL is that 

Licences – examples: Data you OWNIt‟s yours! What do you want to do with it?

Licences – Take Home PointsPrior to using data find out the licensing constraints• Licence holders ARE litigious – they have every right to sue you if you infringe their licenceIf you buy data – ensure you licence this for as broad a re-usebase as possible (NEVER licence to an individual)If you own data – always provide it to others with a CLEAR re-use licence• If you want credit include an attribution clauseDO NOT derive maps etc. from Google Earth data – it is illegal

Licences – DART (www.dartproject.info)DART does the following:• For data under licences: • Ensures broad access • Opens data where possible (NERC ARSF) • Encourages re-use• For data it owns: gives it away • Data: Open Data Commons By Attribution licences (http://opendefinition.org/licenses/odc-by/) • Everything else: Creative Commons By Attribution licences (CC-By: http://opendefinition.org/licenses/cc-by/)• Why • Open Science

Open Data: Server (in the near future)The full project archive will be available from the server Raw Data Processed Data Web ServicesWill also include TDR data Weather data Subsurface temperature data Soil analyses spectro-radiometry transects Crop analyses Excavation data In-situ photos ETC.

Why are we doing this – spreading the love

Why are we doing this – it‟s the right thing to doDART is a publically funded projectPublically funded data should provide benefit to the public

Why are we doing this – IMPACT/unlocking potentialMore people use the data then there is improved impactBetter financial and intellectual return for the investors

Why are we doing this – innovationReducing barriers to data and knowledge can improveinnovation

Why are we doing this – educationTo provide baseline exemplar data for teaching and learning

Why are we doing this – building our networkFind new ways to exploit our dataDevelop contactsWrite more grant applications
