public class NcxCrawler

extends java.lang.Object

Java standalone application to crawl recursively a local directory tree and extract the metadata from all netcdf files. Metadata files may be stored in a parallel directory tree rooted at the specified location, or all in the same directory. NcxCrawler calls repeteadly the processing method of Ncx to do the actual processing. Note: because of security restrictions, application will work on local netcdf files only Note: existing metadata files will be overwritten
