Creating a geospatial range within metadata

[EOGrady21]

I am representing a dataset which was collected between a range of spatial points (zooplankton images captured from a towed instrument). I do not have the exact lat/lon points for each individual record, but want to capture the range within the event level metadata. Is there a standard way to extend metadata names? Such as decimalLatitudeStart decimalLatitudeEnd?

(I'm very new to dwc, thank you for your patience and advice!)

Welcome to the DwC world and I'm glad you're taking the time to ask these questions!

Here is some good advice from the OBIS manual: https://manual.obis.org/common_qc.html#uncertain-geolocation
and some similar material from the GBIF IPT manual: https://ipt.gbif.org/manual/en/ipt/latest/data-quality-checklist#where-did-the-event-take-place

In short, you probably want to use the footprintWKT term to define a line or polygon, instead of designating a point via decimalLongitude and decimalLatitude.
