Portal

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.

Basic elements

After logging in:

  1. Log in or out and manage your account

  2. Make and access favourites

  3. Switch to graph view

  4. Open export screen

  5. Links to partner platforms and applications

  6. Zoom in and out on map

  7. Search for addresses, dates, names or codes/tags

  8. Open and close data menu

  9. Selection tools to query data on the map

Data menu and layers

The topmost entry in the data menu toggles between the following base layers:

  • Neutral

  • Topography

  • Satellite

Click a data layer to activate it.

Note

Data layers need to be active to retrieve information from them in the map.

Tip

You can rescale the colour scale of the elevation layer (DEM) >> Double click the layer in the menu.

Adjust the opacity by clicking the green bar below the activated data layer.

Upon activating a raster layer a crosshair appears. By clicking it the application zooms to the full data extent, both in space and time.

Add more data

Want to see more or other data layers? Just add data that is available to your organisation.

Hit the button in the bottom of the data menu: Add data. Clicking the cross (x) in the layer bar removes it from the menu instantaneously.

Below is the ‘Add data interface’. Use the search bar (1) to navigate through the data layers that you or your organisation are authorized to see.

Close the Add data interface (2) and go back to the data menu.

One of the available data layer types is 3Di scenarios. A scenario is a combination of layers and products that belong to a 3Di model run. Click a scenario layer to expand it and activate data layers or download products.

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)

Graph view

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.

Note

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.

Tip

Adjust the colour of a line by choosing from the scale that opens by clicking the coloured bar.

Tip

Drag multiple time series items into one graph to combine them.

Tip

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.

Apps

In order to examine your data in further detail open one of our partner platforms through the Apps screen.

Note

Apps are not available by default in every Lizard portal.

Share

Lizard enables sharing asset, time series and raster data between organisations to provide (water) managers with a better overview of systems and processes.

Favourites

You can save a Lizard state with data of one or more assets, maps or time series as a favourite and share it with others.

_images/e_portal_08.jpg

Open the Favourites dropdown and enter a name/short description. You can save a specific period or one that is relative to ‘now’. In that case, the favourite is always up to date.

Click a favourite to load the Lizard state that was saved in it. A link to the favourite can be retrieved by clicking the blue symbol next to the delete button.
