open()

bool ossimQuickbirdMetaData::open

(

const ossimFilename &

imageFile

)

Open method that takes the image file, derives the metadata, header and rpc files, then calls parse methods parseMetaData, parseHdrData, and parseRpcData.

Parameters

imageFile

Usually in the form of "po_2619900_pan_0000000.tif".

Returns

true on success, false on error.
