The Geomap panel visualization allows you to view and customize the world map using geospatial data. You can configure various overlay styles and map view settings to easily focus on the important location-based characteristics of the data.
Map View
The map view controls the initial view of the map when the dashboard loads.
Initial View
The initial view configures how the GeoMap panel renders when the panel is first loaded.
-
View sets the center for the map when the panel first loads.
-
Fit to data fits the map view based on the data extents of Map layers and updates when data changes.
-
Data option allows selection of extent based on data from “All layers”, a single “Layer”, or the “Last value” from a selected layer.
-
Layer can be selected if fitting data from a single “Layer” or the “Last value” of a layer.
-
Padding sets padding in relative percent beyond data extent (not available when looking at “Last value” only).
-
Max Zoom sets the maximum zoom level when fitting data.
-
-
Coordinates sets the map view based on:
-
Latitude
-
Longitude
-
-
Default Views are also available including:
-
(0°, 0°)
-
North America
-
South America
-
Europe
-
Africa
-
West Asia
-
South Asia
-
South-East Asia
-
East Asia
-
Australia
-
Oceania
-
-
-
Zoom sets the initial zoom level.
Map layers
The Geomap visualization supports showing multiple layers. Each layer determines how you visualize geospatial data on top of the base map.
Types
There are three map layer types to choose from in the Geomap visualization.
-
Markers layer renders a marker at each data point.
-
Heatmap layer visualizes a heatmap of the data.
-
GeoJSON layer renders static data from a GeoJSON file.
There are also five layer types that are currently in alpha.
-
Night / Day layer (Alpha) renders a night or day region.
-
Icon at last point (alpha) renders an icon at the last data point.
-
Dynamic GeoJSON (alpha) styles a GeoJSON file based on query results.
-
Route (alpha) render data points as a route.
-
Photos layer (Alpha) renders a photo at each data point.
Layer Controls
The layer controls allow you to create layers, change their name, reorder and delete layers.
-
Add layer creates an additional, configurable data layer for the Geomap visualization. When you add a layer, you are prompted to select a layer type. You can change the layer type at any point during panel configuration. See the Layer Types section above for details on each layer type.
-
The layer controls allow you to rename, delete, and reorder the layers of the panel.
-
Edit layer name (pencil icon) renames the layer.
-
Trash Bin deletes the layer.
-
Reorder (six dots/grab handle) allows you to change the layer order. Data on higher layers will appear above data on lower layers. The panel will update the layer order as you drag and drop to help simplify choosing a layer order.
-
You can add multiple layers of data to a single Geomap panel in order to create rich, detailed visualizations.
Location
The Geomap panel needs a source of geographical data. This data comes from a database query, and there are four mapping options for your data.
-
Auto automatically searches for location data. Use this option when your query is based on one of the following names for data fields.
-
geohash: “geohash”
-
latitude: “latitude”, “lat”
-
longitude: “longitude”, “lng”, “lon”
-
lookup: “lookup”
-
-
Coords specifies that your query holds coordinate data. You will get prompted to select numeric data fields for latitude and longitude from your database query.
-
Geohash specifies that your query holds geohash data. You will be prompted to select a string data field for the geohash from your database query.
-
Lookup specifies that your query holds location name data that needs to be mapped to a value. You will be prompted to select the lookup field from your database query and a gazetteer. The gazetteer is the directory that is used to map your queried data to a geographical point.
Markers layer
The markers layer allows you to display data points as different marker shapes such as circles, squares, triangles, stars, and more.
Markers have many customization options.
-
Marker Color configures the color of the marker. The default
Single color
keeps all points a single color. There is an alternate option to have multiple colors depending on the data point values and the threshold set at theThresholds
section. -
Marker Size configures the size of the marker. The default is
Fixed size
, which makes all marker sizes the same regardless of the data points. However, there is also an option to scale the circles to the corresponding data points.Min
andMax
marker size has to be set such that the Marker layer can scale within this range. -
Marker Shape allows you to choose the shape, icon, or graphic to aid in providing additional visual context to your data. Choose from assets that are included with Grafana such as simple shapes or the Unicon library. You can also specify a URL containing an image asset. The image must be a scalable vector graphic (SVG).
-
Fill opacity configures the transparency of each marker.
Heatmap layer
The heatmap layer clusters various data points to visualize locations with different densities. To add a heatmap layer:
Click on the dropdown menu under Data Layer and choose
Heatmap
.
Similar to Markers
, you are prompted with options to
determine which data points to visualize and how you want to visualize
them.
-
Weight values configure the intensity of the heatmap clusters.
Fixed value
keeps a constant weight value throughout all data points. This value should be in the range of 0~1. Similar to Markers, there is an alternate option in the dropdown to automatically scale the weight values depending on data values. -
Radius configures the size of the heatmap clusters.
-
Blur configures the amount of blur on each cluster.
GeoJSON layer
The GeoJSON layer allows you to select and load a static GeoJSON file from the filesystem.
-
GeoJSON URL provides a choice of GeoJSON files that ship with Grafana.
-
Default Style controls which styles to apply when no rules above match.
-
Color configures the color of the default style
-
Opacity configures the default opacity
-
-
Style Rules apply styles based on feature properties
-
Rule allows you to select a feature, condition, and value from the GeoJSON file in order to define a rule. The trash bin icon can be used to delete the current rule.
-
Color configures the color of the style for the current rule
-
Opacity configures the transparency level for the current rule
-
-
Add style rule creates additional style rules.
