• Click a field shape to select a catchment.
• Selected catchments are highlighted on the map.
• Selecting one field in a multi-field catchment will select the entire catchment.
• The colours indicate the farmlet that the catchment belongs to.
• Striped fields indicate fields that have changed or are no longer used, but for which data is still available before a certain date.

• Drag horizontally to zoom in on the x-axis.
• Drag vertically to zoom in on the y-axis.
• The date window underneath the chart shows the sum of all line heights in the plot. This helps to identify the position of data.
• Adjust the date window under the chart to zoom on the x-axis.
• Drag the date window, or the main plot area to change the visible data.
• Double click on the plot area to reset the zoom.

• Due to download-time limitations, a maximum of 1 year of data can be downloaded at a time.
• For previewing the data, select variables from the accordion from Water Flow and Properties; Soil Moisture and Precipitation; and MET Station categories only. Note that data from Livestock, Field Event and Field Survey categories cannot be previewed this way.
• Variables can be mixed from the different categories above.
• For all data categories except MET Station, at least one variable and one catchment (from the map) must be selected in order to preview and/or download the data. For the MET Station data, it is not necessary to select a catchment from the map as it is not catchment-specific.

Some downloads may take a number of minutes to retrieve the requested data. Downloads will be slow if requesting a large amount of time-series data and/or several different types of data, particularly livestock data. With livestock data, the querying of data for given selection criteria can be complex, so that even if only a small amount of data, or none at all, is returned, it may take some time for the preparation of the download to complete.

Please be aware that when opening exported data in a spreadsheet, the spreadsheet might interpret certain columns incorrectly. E.g. in the Field Events data-file, some fertiliser application names contain dashes (e.g. 21-8-11), which can be misinterpreted as dates by certain spreadsheet software.
