Improving parsing of Mercator_1SP / Mercator_2SP projection on geotiff metadata
adapters
----------------------------------------------------------------------------------------
Key: GEOT-2163
URL: http://jira.codehaus.org/browse/GEOT-2163
Project: GeoTools
Issue Type: Improvement
Components: core coverage
Affects Versions: 2.5.1
Reporter: Daniele Romagnoli
Assignee: Daniele Romagnoli
Fix For: 2.5.2
GeoTIFF only contains definition for CoordinateTransformation code 7 =
Mercator, no matter if it is referring to Mercator_1SP or Mercator_2SP.
In order to check if geotiff metadata is identifying a Mercator_2SP, we need to
look for a GeoKey ID 3078 => Latitude of Primary Standard Parallel.
Moreover, when parsing a ParameterValueGroup referring to a MapProjection, we
need to check if it contains a parameter identified by "standard_parallel_1".
CRS2GeoTiffMetadataAdapter and GeoTiffMetadata2CRSAdapter need to be adjusted
to handle both cases (1sp/2sp) by leveraging on the proper parameter.
