GeoKeyEntry
All Implemented Interfaces:
Comparable<GeoKeyEntry>

public final class GeoKeyEntry extends Object implements Comparable<GeoKeyEntry>
This class is a holder for a GeoKey record containing four short values as specified in the GeoTiff spec. The values are a GeoKey ID, the TIFFTag number of the location of this data, the count of values for this GeoKey, and the offset (or value if the location is 0).

If the Tiff Tag location is 0, then the value is a Short and is contained in the offset. Otherwise, there is one or more value in the specified external Tiff tag. The number is specified by the count field, and the offset into the record is the offset field.

    • compareTo

      public int compareTo(GeoKeyEntry o)
      According to GeoTIff spec:

      In the TIFF spec it is required that TIFF tags be written out to the file in tag-ID sorted order. This is done to avoid forcing software to perform N-squared sort operations when reading and writing tags.
