When geographic data is available, performing data analysis using maps is very visual as the data is displayed in a specific geopositioned context.
In Biuwer, map cards accept multiple queries, which means that maps can be created with one or more layers, with data from different Data Models, or in other words, from one or different data sources.
Configuration of a Map Card in Biuwer
In this case, the initial configuration includes:
- Show a base map and which base map, among the available options
- Location of the centre of the map (can be specified by manual input of latitude and longitude, or by using the map itself)
- Map zoom level (can be specified by manual input or by using the map itself)
- Other controls on the map (zoom, layer selector, allow zoom with the mouse)
To configure a layer, click on the "Add" button at the top right of the "Layers" block and in the create/edit layer dialog, indicate a name for the layer, the type of map layer to include and the query from which to obtain the data fields.
Editing a layer on a Map card
Each data layer you want to include in the map requires its own configuration. For example, to configure a symbol layer you can set the following:
- How to locate each symbol (e.g. using two data fields indicating the latitude and longitude of the symbol).
- What is the size of the symbol, whether it is fixed or dynamic depending on the value of a data field.
- What is the colour and icon of the symbol, if it is fixed or dynamic according to the value of a data field.
- What is the border of the symbol.
- Whether tooltips (pop-up data layers) will be displayed when the mouse is moved over symbols and/or when they are clicked on, and what information will be displayed.
Setting up a layer of symbols on a map card
As with chart cards, possibilities offered by the map card are very extensive and can be adapted to a multitude of needs and the imagination of the user.
