The o2a.GeoTiff Format is a specification of the metadata tags nomenclature inside a GeoTiff used in the o2a dataflow. It extends the GeoTiff Format with defined metadata tags which are needed for the o2a dataflow.
Definition for Format version 1 is in progress and is not yet proofed.
An GeoTiff with defined metadata tags. The advantage is to store the SensorURN and/or DOI and/or additional metadata tags in the file.

GeoTiff with well formed WKT description of the coordinate system and additional defeined metadata tags holding dateset specific informations.
Coordinate System | The Coordinate System (SRS,CRS) must be in written in the WKT format and must be valid against it. If not, it won't be accepted. e.g. WKT of EPSG:4326: https://epsg.io/4326.wkt |
PARAMETER_URN | The sensor or parameter urn of the dataset as defined in sensor.awi.de. It will be used for decisions in the o2a dataflow. e.g. 'satelite:gcomw1:amsr2:l2:sic' |
PARAMETER_UNIT | The unit of the given parameter e.g. '%' |
DOI | If the dataset is coming from PANGAEA, the DOI is used for identification. e.g. 'PANGAEA.123456' |
The metadata tags must be tested in the processing workflow.
