Abstract
A method and system for accessing geodata. Geodata input (source) files in various formats are converted to downloadable archive files. The input files are also used to derive metadata file associated with maps represented by the geodata. The archive files and associated metadata files are stored in a repository. A metadata harvester accesses the metadata in the repository and builds a database. A web server and web-enabled end user computer communicate via the Internet to provide the user with an interactive interface for searching the metadata database. The user is provided with metadata and links to the archive files.
