Queensland Museum provider for OZCAM

Description :

 Queensland Museum provider for OZCAM
Queensland Museum collections date back to the 1860s. Many early specimen records contained incomplete or inaccurate spatial information and in such cases, no interpretation of accuracy has been applied herein. When the museum commenced databasing in the mid-1980s, terms were introduced to represent assumed accuracies of collecting information. The terms below are a refinement of disparate lists and have been used for mapping to the Darwin Core field 'coordinateUncertaintyInMeters'. The table below shows how the terms are represented in metres of accuracy and the assumptions made in assigning these values.

Term    coordinateUncertainty
InMeters    Assumptions
Surveyed (ground control)	1	International Terrestrial Reference Frame is used for ground survey mapping
Google Earth	20	Latitude and longitude taken from Google Earth by positioning cursor over land feature
GPS reading	50	In-field GPS reading, but correct datum is not assumed
Collector's data	500	Generalised - usually legacy data, pre-GPS
Centrepoint of geographic unit	1000	Centroid values used when no other, more accurate method has been recorded, (e.g. "Fraser Island").
Gazetteer	1000	Gazeteer values used when no other, more accurate method has been recorded,(e.g. "Bundaberg, Queensland").
Geographic location given	1000	Gazeteer values used when no other, more accurate method has been recorded, (e.g. "Blue Lake").
Point in Polygon method	10000	Centroid values used when no other, more accurate method has been recorded, (e.g. "Springbrook National Park").
Regional Approximation	10000	Centroid values used when no other, more accurate method has been recorded, (e.g. "Torres Strait").

Le jeu de données diffusé est issu d'un traitement automatique appliqué sur les données issues du GBIF. Les règles de l'INPN et plus globalement du SINP (en termes de périmètre et de contrôle sur les données) peuvent impliquer que l'ensemble des données du jeu source ne soit pas restitué dans le SINP.
 The disseminated dataset stems from an automatic treatment applied to data coming from GBIF. INPN rules, and more generally SINP rules (in terms of perimeter and data quality controls) may imply that the whole of the source dataset might not be provided on the SINP platform.
