How does the download process work for requested maps?

The download process now requires the use of an e-mail account for delivery of the map information summary and a link for downloading the requested map. This process has been adopted because very few mine maps are actually available on the FTP server at any given time. Most map downloads are packaged at the time of the actual request and any map package that hasn't been requested in over seven days is automatically deleted from the FTP server. This approach allows us to serve up several hundred gigabytes of map data while using less than 25 gigabytes of FTP data storage.

Each time a map is requested the web service checks to see if a pre-packaged version of the request is currently available on the FTP server. If the map package is available then the map summary and download link is immediately sent to the specified e-mail address and a 'Download Now' link is provided on the web page announcing that the map request is being processed. You can click on the download link on the web page to initiate the download process at that time (you will still get an e-mail).

If the map package is not available then the web service queues up the automated packaging process and the map notification e-mail is sent out when the package is ready on the FTP server. Most map packages are processed within a few minutes of the request. If you do not want to wait for the e-mail notification to make it through the internet then you can click on the 'Check Download Availability' button and the web page will check for download availability every two seconds until the requested map has been packaged. Once the map download is ready you will be presented with the 'Download Now' link.
