Interactive map

In the interactive map measurement nets (called groups in the portal) can be inspected visually. The page consists of 4 components.

Buttons

In the top left corner of the page there are 6 buttons.

Select map layers

This opens the map layers menu.

Base Layers lets you choose between a regular map view or satellite images of the map.

Overlays NL/BE contains several map layers which add extra information to the map.

Select single sensor

This button, which is enabled by default, lets you select a single measurement point. The metadata of the measurement point is displayed in the sidepanel and its measurement data is loaded into the graph.

Select multiple sensors

This button lets you select multiple measurement points, whose metadata is loaded into the sidepanel in separate tabs and their measurement data is loaded into the graph. This allows comparison between the measurement points.

Select sensor area

If all measurement points in a certain area need to be selected, this button can be used. Click and hold the left mouse button and pull a rectangle around the desired measurement points. The sidepanel and graph display metadata and measurement data, just like the select multiple sensors button.

Query map layer

Use this button to click on the map and get information about the chosen location in the sidepanel.

Note: this only works for the map layers "AHN" and "KRW".

Display map in fullscreen

This displays the map in full screen.

Property selection

The property selection consists of 3 parts.

 

Well depth

The well depth selection is a filter for the map that only shows measurement points of which its water level is within the chosen depths.

 

Sensor Variable

The sensor variable selection changes the displayed information inside the measurement points on the map.

• Water level: Shows the water level in meter NAP. This is the default value.
• Dewatering: Uses color and numbers to show how much dewatering a measurement point has compared to the ones around it.
• Sensorstatus: Displays the state of the sensor. The options are:
  • OK: everything is working properly
  • Data: no data is being measured
  • Node: no node (sensor) is coupled to the measurement point
  • - : the measurement point is not being used
  • Err: some other error situation is present
• Measuring Networks: Shows the measurement points for every selected measuring network in a different color.
• Lab results: Opens a new option that allows the selection of various substances that could be measured in the measurement point (if the node supports it).
• Sensor Description: Shows the description of the measurement point.

 

Show interpolation

This checkbox can be checked for sensor variables "water level" or "dewatering". It generates a honeycomb pattern of water level/dewatering between the measurement points.

Note: these are calculated values based on the measurements of the measurement points and can deviate from reality.

 

Sidepanel

The sidepanel consists of 5 icons:

	Show/hide sidepanel: opens or closes the sidepanel.
	Measuring Networks: Allows you to choose the groups to be displayed on the map.
	Measurement point details: is opened automatically when choosing a measurement point and displays its metadata, like the tube schematic and the logbook.
	Overly details: Shows the details of the chosen point on the map. Which details are shown depends on the chosen map layer(s).
	Legend: Show information about the selected map layer(s). This is independent from any chosen measurement point.

Graph

The graph displays the measurement data of the chosen measurement point(s). By default the past year of data is displayed; this can be changed by selecting a specific period in the data selector to the left or by using one of the presets of 1 month, 1 year or 3 years.

It is possible to step in increments of 1 day/week/month through the graph. In doing so, the displayed measurement points change with it to display the change in water level over time. Move the vertical red line to the place where playback should start and press the "Play"-button.

Using the arrow up/down the graph can be enlarged; the button next to it hides the entire graph panel.
