Well-Known Text (WKT) provides a representation of the geoemtry of a location and can be provided in footprintWKT
. This is particularly useful for tracks, transects, tows, trawls, habitat extents, or when an exact location is not known. You can use the OBIS Maptool (Figure 2.1) to generate WKT, calculate midpoints of lines and polygons, and determine the radius of a polygon or line. Midpoints can used to populate decimalLongitude
and decimalLatitude
, while the radius can be used to populate coordinateUncertaintyInMeters
. Additionally, an obistools R function can calculate centroids and radii. To visualize and share WKT strings, try wktmap.com.
