| GridCoverageExchange | | public class GridCoverageExchange (Code) | | Support for creation of grid coverages from persistent formats as well as exporting a grid
coverage to a persistent formats. For example, it allows for creation of grid coverages from the
GeoTIFF Well-known binary format and exporting to the GeoTIFF file format. Basic implementations
only require creation of grid coverages from a file format or resource. More sophesticated
implementations may extract the grid coverages from a database. In such case, a
GridCoverageExchange instance will hold a connection to a specific database and
the
GridCoverageExchange.dispose method will need to be invoked in order to close this connection.

| getReader | | public GridCoverageReader getReader(InputStream source, CoverageOffering description, Envelope envelope, Format format) throws IOException(Code) | | This method is a deegree specific enhancement of the GridCoverageExchange
class/interface as defined by GeoAPI. Returns a grid coverage reader that can manage the
specified source
Parameters:
source - An object that specifies somehow the data source.
Parameters:
description - an object describing the grid coverage and the access to avaiable metadata
Parameters:
envelope -
Parameters:
format - The grid coverage reader.
throws:
IOException - if an error occurs during reading. |
| getReader | | public GridCoverageReader getReader(Object resource, CoverageOffering description, Envelope envelope, Format format) throws IOException, InvalidParameterValueException(Code) | | This method is a deegree specific enhancement of the GridCoverageExchange
class/interface as defined by GeoAPI. Returns a grid coverage reader that can manage the
specified source
Parameters:
resource - a string that specifies somehow the data source (e.g. a file).
Parameters:
description - an object describing the grid coverage and the access to avaiable metadata
Parameters:
envelope -
Parameters:
format - The grid coverage reader.
throws:
IOException - if an error occurs during reading. |
| getReader | | public GridCoverageReader getReader(Object[] resources, CoverageOffering description, Envelope envelope, Format format) throws IOException, InvalidParameterValueException(Code) | | This method is a deegree specific enhancement of the GridCoverageExchange
class/interface as defined by GeoAPI. Returns a grid coverage reader that can manage the
specified source
Parameters:
resources - an array strings that specifies somehow the data sources (e.g. some files).
Parameters:
description - an object describing the grid coverage and the access to avaiable metadata
Parameters:
envelope - The grid coverage reader.
throws:
IOException - if an error occurs during reading. |
| getWriter | | public GridCoverageWriter getWriter(Object destination, Format format) throws IOException(Code) | | Returns a GridCoverageWriter that can write the specified format. The file format name is
determined from the
Format interface. Sample file formats include:
| "GeoTIFF" |
- GeoTIFF |
| "PIX" |
- PCI Geomatics PIX |
| "HDF-EOS" |
- NASA HDF-EOS |
| "NITF" |
- National Image Transfer Format |
| "STDS-DEM" |
- Standard Transfer Data Standard |
Parameters:
destination - An object that specifies somehow the data destination. Can be ajava.lang.String, an java.io.OutputStream, ajava.nio.channels.FileChannel, whatever. It's up to the associated gridcoverage writer to make meaningful use of it.
Parameters:
format - the output format. The grid coverage writer.
throws:
IOException - if an error occurs during reading. |
