The National Vegetation Survey Databank (NVS) and LUCAS Susan Wiser Landcare Research Lincoln, New Zealand MoRST Data Sharing Workshop 25 March 2009 http://nvs.landcareresearch.co.nz/
>77 000 Relevés >19 000 permanent plots
>10,000 new plot records since June 2005 1-2 requests per week Support for standardised data collection Protocols for data use Strand 1: Anticipating and meeting enduser needs
Strand 3: Leadership in synthesis and integration: Integrated with NZ standard taxonomic names database
Geographic standards allow ready integration with spatial layers to show species distributions
Historic relationship between NVS and LUCAS • Original 1990 baseline based on forest data archived in NVS • Variance in C estimates at different grid densities guided plot network density • Plot protocols extended Forest Service 20 x 20 protocol • 16% of plots in LUCAS natural forests network predated the network; data archived in NVS • LUCAS holds copy of historic data from pre-existing plots • Paper and electronic copies of all above-ground data from LUCAS plot network archived in NVS LUCAS
Why is LUCAS data archived in NVS? • Provide a conduit for discovery and usage of LUCAS data by a wider range of endusers • One query against both databases more efficient for endusers • Continuity for remeasurement of LUCAS plots in pre-existing networks • Formats compatible with NVS-specific analytical software and other packages Endusers LUCAS
How this works: archiving data • Tables/fields mapped onto NVS tables/fields • Validation checks LUCAS 3. Recent corrections added 4. Validation queries LUCAS
How this works: data requests Request data Provide permissions Endusers Inform of permission required Provide data Obtain permission LUCAS Private Landowners
Where to from here? • Further work on versioning • Move towards using an exchange standard and distributed databases
