Use whichever method you prefer. The further you drag, the faster it tilts. Click on one of the Base map thumbnails to select the type of map to view. Control + left-click and drag left or right over the map to rotate the view about the centre (on Windows systems you can also use Middle-click and drag). More details on using this functionality can be found under [https://map.drought.gov.au/help/charts.html] “How to work with charts” section of the help pages or by watching this video. When a data set is added to the map via the Data Catalogue, a legend for that data set will appear at the top of your Data Workbench (pictured above). Move your mouse pointer over the map and use the scroll wheel to zoom in or out. Data sets displayed in the Data Catalogue are directly referenced from a server provided by the relevant department or agency. The splitter would section the screen to allow comparison between views on the “left” and “right”.The calendar in the workbench allows users to select the year and month. A wealth of spatial data has been made available through National Drought Map, all of which can be accessed via the Data Catalogue. Here we present a range of drought indicators. The maps or images are draped over a smooth globe. From the Data Workbench you can: The splitter and date picker can be used to visualise data for a location at different times or different datasets for the same time. When you are in Perspective View, Control + left-click and drag left or right over the map to “orbit” around the centre of the view. None of these methods are "the best" indicator of drought, because it very much depends upon the application of the information (i.e. The calibration period for the SPEI is January 1950 to December 2010. The National Drought Map does not store any of the data it serves. Hint: In Australia, Cradle Mountain and Katoomba are good places to use for experimenting with Perspective View. Close the dialog by clicking the X at the top right or clicking again on the Base Maps button. This drought was monitored closely and is discussed more fully below. for water supply calculations, for irrigation potential, for pasture production estimates, etc.). The Standardised Precipitation Index (SPI) is a simple measure of drought (and also of very wet conditions) and is based solely on the accumulated precipitation for a given time period. There are several ways of defining drought and several methods for identifying whether a drought has started. For each drought indicator, we have identified the threshold values which can be used to indicate whether drought conditions are "imminent" and/or "likely evident". Hint: Mouse over the Compass Control (pictured below) to see help on its use. NASA Black Marble, and Natural Earth II may show as completely one colour if you are zoomed in too far. Select 3D Terrain to show a Perspective View which shows the elevation changes in the terrain. These are maps of the soil moisture deficit (SMD) and the standardised precipitation index (SPI) - both updated daily, as well as maps of rainfall deciles (RD) - updated monthly. This agreement continues to build on drought policy reform including moving away from Exceptional Circumstances arrangements and associated lines on maps to qualify for drought support. None of these methods are "the best" indicator of drought, because it very much depends upon the application of the information (i.e. Copyright, NIWA. Move your mouse pointer over the map and use the scroll wheel to zoom in or out. To do this, simply click on the title of a data set and drag it to a new position in your Workbench. The National Drought Map is a new online tool that brings together population data and information on drought conditions.. The Department of Primary Industries and Regional Development provides data and information on seasonal weather through its network of automatic weather stations and seasonal climate forecasts through … CSIRO Data61 2014-2019. This trend is expected to continue, with dry seasons likely to become more frequent over southern Western Australia. The National Drought Map is a Central Analytics Hub (CAH) project which aims to help meaningful support reach drought affected farmers and communities. When in 3D mode, click on the “gyroscope” in the centre of the Compass Control (picture above) and drag slowly upwards to tilt the view into a Perspective View. All Rights Reserved, Share my National Drought Map view with others and/or print, Work with the Satellite Imagery and the splitter functionality. Activate the tool (pictured above), click on one point on the map and then another. It also makes drought data easy to access by the public. Release the mouse button when you reach the desired rotation. Zooming. Control + mouse left-click and drag upwards or downwards over the map to enter or adjust the perspective view. Splits the screen in “left” and “right” sections to allow comparisons between views of the same data at different points in time or different datasets. However, we stress here that this information should be used for guidance only and is not the sole source of information used in the official declaration of droughts. Toggle the visibility of added data sets. Double-click the “gyroscope” in the centre of the Compass Control to return the view quickly to a vertical view with North to the top at the current location and scale. Australia is a vast country and governments, the private and non-profit sectors are all generating a wealth of data about the drought. In the future, we will also produce maps based on the potential evapotranspiration deficit (PED), which was used as an indicator in the NIWA 2012-2013 drought report. Example soil moisture deficit anomaly map showing, for the particular time of year, drier than normal soils over much of the North Island and wetter than normal soils around Christchurch. (Note that pressing the F5 key on Windows or Command + R on Mac OS will reload the entire National Drought Map web page. Note: 3D Terrain view may give the same result as 3D Smooth or may not work at all on some computers with older graphic cards or older web browser versions. Mouse over the thumbnails to see a hint on what they are. Select 2D to show a vertical map view with north to the top. 3D Smooth and 3D Terrain will look almost the same unless you are using Perspective View. Dragging to Pan and using the Mouse Wheel to zoom still work while showing a Perspective View. Through an online interactive map of Australia, users have easy access to spatial information on drought conditions and support measures to assist with analysis, decision making, planning and reporting. Note: removed data sets can always be re-added via the Data Catalogue. If you list all the historic rainfall totals for a particular month and for a specific location, rank these from lowest to highest, then divide the list into ten equal parts, you have identified the ten rainfall deciles for that month and for that location. (On Windows systems you can also use Mouse middle-click + drag.). Even the topography and road maps can be viewed in perspective. Drag downwards to tilt the view back to vertical. For example, You can see details of the department or agency that provides the spatial data by clicking on the title of your preferred data set in the Data Catalogue. Click on the Maps button to show the Base Map Dialog (pictured below) for changing the base map. Long-term records show that our climate is becoming warmer and drier. Remove data sets from the map. Click on the North Point or outer ring of the Compass Control (pictured above) and drag it around to set the desired rotation directly. Droughts of a lesser degree of severity categorised by Foley (1957) are given in Table 2. The 3-panel Soil Moisture Deficit (SMD) map shows the historical soil moisture deficit at the date shown (left), the soil moisture deficit at the same time last year (middle) and the current soil moisture deficit (right). Australian farming businesses and farming communities are adopting increasingly sophisticated and effective strategies to deal with drought and respond to climate change and variability. The location at the centre of the map display is the centre of the zooming. You can’t simulate looking from under the ground because the system always keeps the “camera position” above the earth’s surface, but you can create a view which is looking only at the sky. Click on the zoom control (pictured above) to zoom in or out quickly by a set amount. (Other very high relief areas like the Grand Canyon or Mount Everest - not the ones in NSW - are also really cool!). This will result in a reset which will show the whole of Australia, but it also results in the total loss of all your context information from the current session, which includes display information and selected Data Sets.
