The portal of Lizard is the graphical user interface (GUI), in which measuring locations, parameters, timeseries, rasters and other layers are visible in maps and graphs.
After logging in:
Log in or out and manage your account
Make and access favourites
Switch to graph view
Open export screen
Links to partner platforms and applications
Zoom in and out on map
Search for addresses, dates, names or codes/tags
Open and close data menu
Selection tools to query data on the map
There are 4 selection tools:
Point selection Point selectionretrieves asset information, time series and map values from the active data layers. Results are displayed on the left.
Use the multipoint tool to select multiple objects and/or locations. When multiple assets are selected, time series are not displayed in the omnibox. Go to the graph view to see them.
Add a set of locations to a favourite to always have them available instantaneously.
Use the line selection tool to retrieve data along a profile, e.g. elevation from a DEM.
1st click: Start point
2nd click: End point
3rd click: Reset
Hovering along the profile on the map shows a corresponding indicator in the graph.
The region selection tool aggregates data of the selected region.
Region analysis can be performed on raster of data type nominal (quantititive) or ordinal (classes). Click the star behind the layer name and the analysis is applied on-the-fly on the active region type for the zoom level. The regions are coloured based on the most abundant class.
Hover over the classes in the diagram to see more information.
Select a class in the legend and the regions are coloured based on the relative abundancy of that class. This answers questions like: what is the general rice growth stage within my district or which municipality is most urbanized?
Graph view and data interpretation¶
There are multiple ways to interpret your data. For example, you can:
Activate multiple layers in order to get a more integral scope on situations or to see interaction between locations.
Export the data and analyse in another program (see next paragraph)
Switch between map view and graph view with the Graph/Map button.
By scrolling or dragging within the graph the domain of the Y-axis can be changed. By scrolling or dragging the datetimebar, the X-axis can be changed.
If multiple locations with time series are selected initially there are no time series displayed. Click time series in the menu to show/hide them.
Adjust the colour of a line by choosing from the scale that opens by clicking the coloured bar.
Drag multiple time series items into one graph to combine them.
Water level time series can be recalculated relative to the surface level. This is done by clicking the button ‘relative’. This enables analysis of drainage depth or freeboard. The option also applies to the export of these time series.
Next to the relative button you can zoom to the standard periods and full extent of the active timeseries.
In order to examine your data in further detail open one of our partner platforms through the Apps screen.
Apps are not available by default in every Lizard portal.
No results shown? Check your selection of space and time and whether you activated the right data layers.
By adding an annotation to an object or location you can make notes or share remarks with others.
Select an object or location on the map while the annotation layer is activated: 1. Write a message 2. Upload a file (max. 15 Mb) to support the message 3. Select the organisation to share the annotation with 4. Save the annotation (or delete one)
