Package org.apache.tika.parser.gdal

Class GDALParser

java.lang.Object

org.apache.tika.parser.gdal.GDALParser

All Implemented Interfaces:

Serializable, org.apache.tika.parser.Parser

public class GDALParser
extends Object
implements org.apache.tika.parser.Parser

Wraps execution of the Geospatial Data Abstraction Library (GDAL) gdalinfo tool used to extract geospatial information out of hundreds of geo file formats.

The parser requires the installation of GDAL and for gdalinfo to be located on the path.

Basic information (Size, Coordinate System, Bounding Box, Driver, and resource info) are extracted as metadata, and the remaining metadata patterns are extracted and added.

The output of the command is available from the provided ContentHandler in the parse(InputStream, ContentHandler, Metadata, ParseContext) method.
