Common Datasets
The Foresight application displays datasets that are common to both Foresight Bushfire and Foresight Planned Burning versions. The Foresight products display key spatial datasets related to fire behaviour indices, fire danger ratings, fuel state, weather and incidents.
Table 2 describes the spatial data layers that are available across all Foresight products and accessed via the Indicators list within the Foresight application.

^Gridded Weather The Gridded Weather is a compilation of datasets (NetCDF files) of forecast weather variables for the present day and the week ahead. The Gridded Weather is produced by the BOM using the Graphic Forecast Editor (GFE) system. The Gridded Weather for Victoria is produced at a 3km resolution using data sourced from a range of global weather forecasting models. The Gridded Weather data files are updated twice daily. A full update of all days in the forecast period occurs in the afternoon update. The morning update (usually completed by 6am) provides updated NetCDF files where only the data for the current day has been updated.*FireMod FireMod uses the Gridded Weather, together with fuel and topography datasets, to calculate a range of forecast fire weather and fire behaviour spatial data sets. The FireMod system is maintained by TSU within Forest, Fire and Regions at DELWP. FireMod will be triggered to run when the BOM release updated Gridded Weather.Footnotes 2 Hines F.,Tolhurst K.G., Wilson A.A.G. & McCarthy G.J. 2010.

Accessing the charts/graphs
When an indicator layer is selected and displayed on the map, there are a few methods of accessing more information about a point of interest. If you select a point on your map with your cursor, then the pop-up box will appear and you can select the ‘charts/graphs’ option to access meteograms for that location, by selecting the graphic on the bottom left-hand side of the pop-up (Figure 4).
Figure 4. Pop-up box at a point location on the map display, showing the charts function selected.
A data display window will pop-up at the right side of the screen. At the top of the data window, information related to the location of the selected point will be displayed, specifically Latitude, Longitude, MGRS Coordinate System location and Phoenix Fuel Type for that location.
Figure 5. Meteogram window (Zoom for improved resolution)
Within each meteogram, the selected date and time is represented by a dashed red line (Figure 6). The solid red line shows the current date and hour (now).
Figure 6. Now and selected time steps
Scrolling over a data point in a meteogram will reveal the numerical value for that indicator at that time step (Figure 7).
Figure 7. Data will appear upon scrolled over
At the top of the meteograms, click ‘Show’ on the ‘History’ button to switch on/off the visibility of the two days prior to the present within the meteograms. Use the ‘Days’ button to switch between visibility of a two-day or seven-day forecast period within the meteograms (Figure 8).
Figure 8. The header page of pop-up meteogram and chart box, showing the history and days functions (Zoom for improved resolution)
AWS are fully automated BOM weather stations that collect a large set of weather variables according to stringent methods. Data is reported on a half hour frequency (Figure 9). Non-AWS are weather stations that generally collect fewer variables and data is usually reported less frequently (e.g. twice daily). Portable weather stations will also appear if any have been deployed in the state.
Figure 9. AWS observation data in a meteogram
If a weather station is within 10km of the selected point, then observation data for the nearest weather station is also shown on the meteogram. This allows comparison of the forecast (predicted) conditions against the observed weather (actual) at the nearby weather station. This is important for helping to assess the reliability of the forecast.
Accessing the data tables
You can also access data tables for the selected point, by selecting the ‘Tables’ option on the bottom middle of the pop-up (Figure 10).
Figure 10. Pop-up box at a point location on the map display, showing the tables function selected.
When you access the data tables, all Foresight versions will present a data table of weather variables (Figure 12). This table data can display forecast history, in the same way as the meteograms. You can also toggle between the meteograms and the data table using the ‘Graphs-Table’ toggle option at the top of the data display screen. The left side of the data table allows display functions to be activated. Background colours can be selected to add legend colours into the table cells according to values, and the wind direction information can be changed to arrows, cardinals or degrees. You can also move the time at the top of the table between ‘now’ and a selected time step.
The weather variables displayed in the data tables are consistent across all Foresight products. Users with Advanced Access to Foresight can manually edit variables that are used in any fire behaviour models. This is done by double-clicking on a data table cell of interest or on the ‘edit’ icon () for the relevant row or column. This will open a pop-up which allows all values contributing to the calculation of that data cell to be edited (Figure 11). Any data that is dependent on edited data will be highlighted in the data table and the map.
The weather variables displayed in the data table are shown in Table 4.
