  2. What is an ideal georeference? A numerical description of a place that can be mappedand that describes the spatial extent of a locality and its associated uncertaintiesas well as possible.

  3. Sharing Requires Standard Terms Darwin Core Location Terms • higherGeography • waterbody, island, islandGroup • continent, country, countryCode, stateProvince, county, municipality • locality • minimumElevationInMeters, maximumElevationInMeters, minimumDepthInMeters, maximumDepthInMeters Darwin Core Event Terms • habitat Darwin Core Geological Context • group, formation, member, bed, …

  4. My field notes? Why darwin core / georeferencing standards? Your field notes? map to a standard! http://www.britishmuseum.org/images/rosettawriting384.jpg

  5. From the Label, Notebook, … field notes your database field darwin core • 41 05 54S • 121 05 34W • WGS84 • 2 mi. NE Tlh. on Ctrville Rd. • Tallahassee, 2.5 miles NE on Centerville Road. • frequent • Wakulla CO. • in moist roadside depression, … • lat or latitude • lon or long or longitude • datum or notes or … • loc or location or collectorLocality or … • abundance • county • habor habitatDescription or … • verbatimLatitude • verbatimLongitude • verbatimSRS • verbatimLocality • locality • (abundanceAsPercent) • county • habitat Note New

  7. Three Ways* to Georeference • Georeference by CSV • Georeference Me! • one-at-a-time (not recommended) Workflow Overview • Where is your locality data? Collate it. • Into a CSV file • file-naming strategy • Upload to GEOLocate • or “Call GEOLocate” using “Georeference Me!” • Use GEOLocate to visualize work before import • Use CSV-file Georeferences to populate your database • or copy-and-paste georeferences directly into database Spotlight on GEOLocate

  8. Georeference by CSV - steps • download form • http://www.museum.tulane.edu/geolocate/sampledata/EmptyGEOLocateFileUncert.csv • populate first 4 columns: Locality String, Country, State, County • in locality string, concatenate fields prn, space between • add columns to uniquely identify localities • barcode, recordid, catalognumber, localityid • add other columns prn: georeferenceProtocol, georeferenceSource, georeferenceVerificationStatus • save file (name files consistently) • go to: http://www.museum.tulane.edu/geolocate/web/WebFileGeoref.aspx • click Select File • click Load (store retrieval file identifier) • georeference in GEOLocate • download (Export) when done (click File Management, select csv) • upload to your database • formatting data as needed for upload to your database

  12. Georeference Me! - steps • download form • http://www.museum.tulane.edu/geolocate/sampledata/GEOLocateAutomation.xlsx • populate first 4 columns: Locality, Country, State, County • in locality*, concatenate fields prn, space between • add columns to uniquely identify localities • barcode, recordid, catalognumber, localityid • add other columns prn: georeferenceProtocol, georeferenceSource, georeferenceVerificationStatus • save file • file can then be divided (among students, for example) • click the Georeference Me! link • adjust the georeference in GEOLocate • copy and paste results into spreadsheet • save file • upload to your database • formatting data as needed for upload to your database *255 characters issue with Excel

  13. Georeference Me!

  14. Georeference 1-at-a-time http://www.museum.tulane.edu/geolocate/web/webgeoref.aspx?

  15. 1-by-1 and a bit more… • GEOLocate, one-by-one • http://www.museum.tulane.edu/geolocate/web/WebGeoref.aspx • Great for a few • For non Specify / non Symbiota users • can put this in your workflow • GEOLocate tool integrated in • Specify and Symbiota • all georeferencing best practices fields are present • GEOLocate - Embeddable version • GEOLocate Collaborative GeoReferencing • tracking + • management time investment -

  16. Trend Proactive Digitization • With maturity of experience (including collectors) and technology • digitization activities in the field: • electronic data gathering, • georeferencing, • field imaging, etc. • may reduce the workload for collections managers. • example: born digital labels Legacy Data Mark Sabaj, Academy of Natural Sciences
