Implications and caveats

Severity: Warning

FootprintSRS is used to supply a Well-Known Text (WKT) representation of the Spatial Reference System (SRS) for the footprintWKT of the Location. Do not use this term to describe the SRS of the decimalLatitude and decimalLongitude, even if it is the same as for the footprintWKT - use the geodeticDatum instead.

A spatial reference system (SRS) or coordinate reference system (CRS) is a coordinate-based local, regional or global system used to locate geographical entities. A SRS commonly defines a specific map projection, as well as transformations between different SRS.

Well-known text representation of coordinate reference systems (WKT or WKT-CRS) is a text markup language for representing spatial reference systems and transformations between spatial reference systems. The formats were originally defined by the Open Geospatial Consortium (OGC) and described in their Simple Feature Access and Well-known text representation of coordinate reference systems specifications. The current standard definition is ISO 19162:2019 (https://www.iso.org/standard/76496.html).

Without this information the ALA is unable to confirm how the location footprint supplied should be interpreted.

Data custodian recommendations

Review spatial system used to define location information supplied.
