Google Maps Geocoding

This is the N4V FOR WEBI Wiki page for the Google Maps Geocoding map widget.

Since Need4Viz 2025.1.9

• Google Map allowing to georeference and geolocate data (by an address) and display a tooltip.
• The definition of a measure also makes it possible to display a circle of variable size around the pin.
• The color of the circle can be given in the optional 4th parameter in RGB format.
• A clickable legend can be defined by the optional fifth parameter (only if the fourth is used).
• Possibility to use the functionality of linked elements on this graph.

• Dimension 1 : Dimension for address
• Dimension 2 : Tooltip size to display on marker/circle
• Dimension 3 : Dimension for Link / Route to reference the marker (for linked elements and the list of route values)
• Dimension 4 : [Optional] Dimension for the color of the circle (RGB value in format # 12AB78)
• Dimension 5 : [Optional] Dimension for the legend to reference the category of the circle

• Measure 1 : Measure the size of the circle

Animations and actions available in this graph :

• The map is adapted and centered to display all your data. You can move the map and enlarge it. This is a Google map, so you can view Google Street View or other forms of the map.
• Moving the mouse over the marker will display the tooltip.
• Click on the marker to display a permanent tooltip.
• If an element link is defined on the graphic, when you click on a marker, the linked graphic is filtered with the corresponding dimension value.
• If you activate the steering module, the right panel can display lists of values to select a route from / to and a mode of travel. When the source and destination are chosen from the lists, the route is plotted on the map and the details of the route are indicated in the right panel.
• If you activate the drawing module, a toolbar is inserted on the map. You can draw circles, markers, lines, polygons … on the map (the area / length are calculated and displayed on the corresponding drawing).
• With the polygon drawing module, you can assign a linked selection to filter the markers inside the drawn polygon. When the polygon is closed, all markers inside the area are selected and can be used to automatically filter other webi blocks (like a lasso selection).

Use the Webi native element link function to make this graph interact with other elements of the same report (native Webi tables / graphs and / or Need4Viz graphs). Element binding can be defined on all objects or individually on one of the dimensions of the graph.

You can find instructions for accessing settings for Need4viz graphics: Format Custom Element.

For the Google Maps Geocoding , the available parameters are :

Extended parameters

• Global → See the user guide for the “Global” section here

• Options
  • Zoom : This setting allows you to set the minimum number of points from which the automatic zoom is active. Under this min number of points, an initial zoom factor can be set. The zoom control and fullscreen buttons can be hidden here. Min and max zoom values can also be positioned.
  • Unit system : You can set the unit system for the distances (kilometers/miles)
  • Map Type : This setting allows you to define the default map type. The map type control buttons can be hidden here.
  • Google markers : You can enable or disable here display of points of interest and traffic markers on the map
  • Streetview : This setting allows you to hide the Streetview button.
  • Thousand separator : This setting allows you to define a thousand separator between space, comma or dot for all the numerical values of the graph.

• Markers
  • Clustering : This setting allows you to use or not markers clustering
  • Google Markers : This setting allows you to hide or not Google default markers

• Geocoding
  • Alerts : This setting allows you to display or not the alerts.
  • Cache : This parameter allows to use or not the cache.

• Measure
  • Measure for the circle size : This setting allows you to specify the unit to add as a measurement prefix or suffix as well as the measurement accuracy. The measurement display format (standard - e.g.: 2,345.67, compact - e.g.: 2.3K or compact long - e.g.: 2.3 thousand) can also be defined.
  • Bubbles markers : This setting allows you to define the arrangement of the circles here (the definition of the min / max radius will be used to represent all the measurement values in this range). Choose the default color (and opacity) of the circles (if the 5th dimension - color - is not used).
  • Measure in tooltip : This setting allows you to hide or not the value in the tooltip.

• Itinary
  • Direction module : This setting allows you to use the direction module (Google route calculation). Define the size and layout of the direction panel.

• Drawing
  • Drawings module : This setting allows you to use or not drawing module
  • Marker : This setting allows you to define if markers can be added by drawing
  • Circle : This setting allows you to define if circles can be added by drawing, and their color
  • Polygons : This setting allows you to define if polygons can be added by drawing, and their color. Polygons can be used to make a multi selection of markers (inside the polygon). You can define here if this functionality is wanted and the name of the input control affected by this selection (a multi value input control has to be set before using this feature).
  • Polylines : This setting allows you to define if polylines can be added by drawing, and their color
  • Rectangles : This setting allows you to define if rectangles can be added by drawing, and their color

• Link element
  • Lasso : Polygons can be used to make a multiple selection of markers (inside the polygon). Here you can define whether this functionality is desired and the name of the input control affected by this selection (a multivalue input control must be defined before using this function).
  • Click on the marker : This setting allows you to activate the dimension 'Link/Itin' as an hyperlink. A click on the marker will open a new windows on this URL.

• Legends
  • General display : This setting allows you to view or not legend (legend is drawn only if 5th & 6th dimension are provided)
  • Colors legend : This setting allows you to set the head legend label. The legend is constructed by colors supplied in 5th dimension. If there are many values in the 6th dimension for the same color, a group label is created, you can change this label here.
  • Sizes legend : This setting allows you to set the size legend label. Also indicate the number of bubbles desired and the precision of the measurement in the legend.
  • Function for color legends : By default, when you click on a legend label, all markers are disabled except the value clicked. You can change this behavior here. With the second function, when a label is clicked, all markers with this value are disabled. Click the label again to activate the markers.
