description varchar 255 √ null

A textual representation of the location, if this is the original georeference. Optional if the original georeference is available in lat/long coordinates.
latitude float4 8,8 √ null

The decimal latitude coordinate of the georeference, using positive and negative sign to indicate N and S, respectively.
longitude float4 8,8 √ null

The decimal longitude coordinate of the georeference, using positive and negative sign to indicate E and W, respectively.
geodetic_datum varchar 32 √ null

The geodetic system on which the geo-reference coordinates are based. For geo-references measured between 1984 and 2010, this will typically be WGS84.
altitude float4 8,8 √ null

The altitude (elevation) of the location in meters. If the altitude is only known as a range, this is the average, and altitude_dev will hold half of the width of the range.
