Sharing Data & Data Models
NVS Data Models
[Edit]NVS data reside in a modern relational database that was developed to meet the varied needs of plot based vegetation data. This conceptual data model has evolved from simple beginnings to one that now caters for a wide range of data types and collection methods. The data model draws from an earlier NVS database design and a similar effort in the USA called VegBank. Note the NVS database implementation may differ from this conceptual model in places for practicality. Component diagrams and defintions were created in 2007-08.
Data Exchange - VegX
[Edit]VegX is an exchange standard for plot-based vegetation data developed by the NVS team in conjunction with an international group interested in a consistent approach for sharing plot-based vegetation data between various data sources. The aim of VegX is to reduce the time consuming task of restructuring data into consistent forms, resolving species names and taxonomy and communicating the methods, data units and levels of precision when aggregating vegetation data. VegX is currently being used by NVS and the BIEN group in the USA. See Wiser et al. 2011. Veg-X - an exchange standard for plot-based vegetation data. Journal of Vegetation Science 22:598-609
