FTP Access to UQ AusCover Server

Last modified by Matt Paget on 2016/11/25 10:37

This is a brief introduction to accessing the AusCover data sets, hosted on the UQ server, via anonymous FTP.

Note for experienced FTP users:

        Host: tern-auscover.science.uq.edu.au.

        This server no longer holds the latest data. See ftp://qld.auscover.org.au and http://qld.auscover.org.au.

        Username: anonymous

Introduction

The UQ AusCover server is the host for many AusCover data sets, including the field and airborne data sets. For most of these data sets, you will be directed to the AusCover THREDDS server for download via http. However, due to the size and complexity of many of the data sets, an anonymous FTP sever has also been established.Once connected to the server via FTP, you will be able to navigate around the data sets and download those of interest.  See the individual data sets' metadata records for details on their location within the server's file structure. 

In addition, because of the consistent filenaming within the server (see AusCover filenaming convention) it is possible to recall multiple records using wget commands.

FTP Clients

There are three main ways to access the data using FTP:

  • Graphical FTP clients
  • Command line FTP
  • Web browser

Graphical FTP client

Graphical FTP clients simplify file transfers by allowing you to drag and drop file icons between a window on the server and a local window. There are many graphical FTP clients available for download. Two free one are:

Below is an example of how to use the FileZilla client to connect to the server. The method for other clients will be slightly different but require similar details. Check your client's documentation for specifics.Two ways to connect are outlined. Firstly using the 'Site Manager' and secondly using the QuickConnect toolbar. Once you connect the server window will appear, showing the data sets.

Using the FileZilla Site Manager

  1. Under the file menu select 'Site Manager'
  2. The Site Manager window will appear (Figure 1)
  3. Select 'New Site' and name the connection appropriately (named FTP in this example)
  4. Enter the following connection parameters in the window, under the 'General' tab:
  • Host: tern-auscover.science.uq.edu.au
  • Protocol: FTP - File Transfer Protocol
  • Encryption: Use plain FTP
  • Logon Type: Anonymous

      5. Press 'Connect'

Using the QuickConnect Toolbar

The QuickConnect toolbar (Figure 2) allows for access to the server with only the following two parameters:

  • Host: tern-auscover.science.uq.edu.au
  • Username: anonymous

Enter the details and click on 'Quickconnect'

Command line FTP

Windows, Mac OS X, and Linux have built-in command line clients. For example, to start FTP in linux, at the command line prompt, enter:

       ftp tern-auscover.science.uq.edu.au

You will then be prompted for a username and password. Use anonymous as your username and email address as your password.  Once connected, you can get some information on basic commands by typing 'help' at the FTP prompt. 

Web browser

You can use a web browser to connect to FTP addresses exactly as you would to connect to HTTP addresses. Click on this address (ftp://tern-auscover.science.uq.edu.au) to connect to the AusCover Server via a web browser. The web browser option offers no benefits over the AusCover THREDDS server and is not recommended.

WGET Commands

Below are listed some example wget commands to recall various field datasets.  These datasets rely on the AusCover filenaming convention:

To recall all site data for site at longitude 140.57526 and latitude -34.00289 on the date of 2012-12-18

wget   -r  -nd --no-parent -A "*14057526e03400289s_20121218*" ftp://tern-auscover.science.uq.edu.au/field_and_airborne_datasets/field/--

To recall any gp (ground pulse) scan located at longitude 133.10:

wget   -r  --nd --no-parent -A "gp*13310*.zip" ftp://tern-auscover.science.uq.edu.au/field_and_airborne_datasets/field/--

To recall all hemispherical photos for longitude 14057526:

wget   -r  --nd --no-parent -A "*hm*14057526*" ftp://tern-auscover.science.uq.edu.au/field_and_airborne_datasets/field/--
