What we have:Specimens with Textual Localities
“Davis, Yolo County, California”
“point method”
Coordinates: 38.5463 -121.7425Horizontal Geodetic Datum: NAD27
What is an acceptable georeference?
A numerical description of a place that can be mapped
and that describes the spatial extent of a locality
and its associated uncertainties.
“Davis, Yolo County, California”
“bounding-box method”
Coordinates: 38.5486 -121.754238.545 -121.7394
Horizontal Geodetic Datum: NAD27
“Davis, Yolo County, California”
“point-radius method”
Coordinates: 38.5468 -121.7469Horizontal Geodetic Datum: NAD27Maximum Uncertainty: 8325 m
What is an ideal georeference?
A numerical description of a place that can be mapped
and that describes the spatial extent of a locality
and its associated uncertaintiesas well as possible.
point easy to produce no data quality
bounding-box simple spatial queriesdifficult quality assessment
point-radius easy quality assessmentdifficult spatial queries
shape complete representationcomplex
Method Comparison
MaNIS Localities Georeferenced
n = 326k localities (1.4M specimens)r = 14 localities/hr (point-radius method)
t = 3 yrs (~40 georeferencers)
Scope of the Problem for Natural History Collections
~2.5 Giga-records
~6 records per locality*
~14 localities per hour*
* based on the MaNIS Project

Beyond 1 September 2006
Seek Industry Support for Data Layers
Develop Workbench into Collaboratories
Develop Locality Interpretation in Additional Languages
Why do all of this?
So that those who generate and care for the data
can realize and share its potential.
