Geomap

Geomaps allow 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.

We would love your feedback on geomaps. Please check out the open Github issues and submit a new feature request as needed.

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 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

Geomaps support showing multiple layers. Each layer determines how you visualize geospatial data on top of the base map.

Types

There are seven map layer types to choose from in a geomap.

• Markers renders a marker at each data point.
• Heatmap visualizes a heatmap of the data.
• GeoJSON renders static data from a GeoJSON file.
• Night / Day renders a night / day region.
• Route (Beta) render data points as a route.
• Photos (Beta) renders a photo at each data point.
• Network (Beta) visualizes a network graph from the data.

There are also two experimental (or alpha) layer types.

• Icon at last point (alpha) renders an icon at the last data point.
• Dynamic GeoJSON (alpha) styles a GeoJSON file based on query results.

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. 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 visualization.
  • 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 visualization 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 in order to create rich, detailed visualizations.

Location

Geomaps need 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.

Basemap layer

A basemap layer provides the visual foundation for a mapping application. It typically contains data with global coverage. Several base layer options are available each with specific configuration options to style the base map.

Types

There are four basemap layer types to choose from in a geomap.

• Open Street Map adds a map from a collaborative free geographic world database.
• CARTO adds a layer from CARTO Raster basemaps.
• ArcGIS adds a layer from an ESRI ArcGIS MapServer.
• XYZ adds a map from a generic tile layer.

Default

The default base layer uses the CARTO map. You can define custom default base layers in the .ini configuration file.

Configure the default base layer with provisioning

You can configure the default base map using config files with Grafana’s provisioning system. For more information on all the settings, refer to the provisioning docs page.

Use the JSON configuration option default_baselayer_config to define the default base map. There are currently four base map options to choose from: carto, esri-xyz, osm-standard, xyz. Here are some provisioning examples for each base map option.

• carto loads the CartoDB tile server. You can choose from auto, dark, and light theme for the base map and can be set as shown below. The showLabels tag determines whether or not Grafana shows the Country details on top of the map. Here is an example:

ini Copy

geomap_default_baselayer = `{
  "type": "carto",
  "config": {
    "theme": "auto",
    "showLabels": true
  }
}`

• esri-xyz loads the ESRI tile server. There are already multiple server instances implemented to show the various map styles: world-imagery, world-physical, topo, usa-topo, and ocean. The custom server option allows you to configure your own ArcGIS map server. Here are some examples:

ini Copy

geomap_default_baselayer = `{
  "type": "esri-xyz",
  "config": {
    "server": "world-imagery"
  }
}`

ini Copy

geomap_default_baselayer = `{
  "type": "esri-xyz",
  "config": {
    "server": "custom",
    "url": "[tile server url]",
    "attribution": "[tile server attribution]"
  }
}`

• osm-standard loads the OpenStreetMap tile server. There are no additional configurations needed and the config fields can be left blank. Here is an example:

ini Copy

default_baselayer_config = `{
  "type": "osm-standard",
  "config": {}
}`

• xyz loads a custom tile server defined by the user. Set a valid tile server url, with {z}/{x}/{y} for this option in order to properly load a default base map. Here is an example:

ini Copy

default_baselayer_config = `{
  "type": "xyz",
  "config": {
    "attribution": "Open street map",
    "url": "https://tile.openstreetmap.org/{z}/{x}/{y}.png"
  }
}`

enable_custom_baselayers allows you to enable or disable custom open source base maps that are already implemented. The default is true.

Markers layer

The markers layer allows you to display data points as different marker shapes such as circles, squares, triangles, stars, and more.

• Size configures the size of the markers. The default is Fixed size, which makes all marker sizes the same regardless of the data; however, there is also an option to size the markers based on data corresponding to a selected field. Min and Max marker sizes have to be set such that the markers can scale within this range.
• Symbol allows you to choose the symbol, icon, or graphic to aid in providing additional visual context to your data. Choose from assets that are included with Grafana such as simple symbols or the Unicon library. You can also specify a URL containing an image asset. The image must be a scalable vector graphic (SVG).
• Color configures the color of the markers. The default Fixed color sets all markers to a specific color. There is also an option to have conditional colors depending on the selected field data point values and the color scheme set in the Standard options section.
• Fill opacity configures the transparency of each marker.
• Rotation angle configures the rotation angle of each marker. The default is Fixed value, which makes all markers rotate to the same angle regardless of the data; however, there is also an option to set the rotation of the markers based on data corresponding to a selected field.
• Text label configures a text label for each marker.
• Show legend allows you to toggle the legend for the layer.
• Display tooltip allows you to toggle tooltips for the layer.

Heatmap layer

The heatmap layer clusters various data points to visualize locations with different densities. To add a heatmap layer:

Click on the drop-down menu under Data Layer and choose Heatmap.

Similar to Markers, you are prompted with various 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 drop-down 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.
• Opacity configures the opacity of each cluster.
• Display tooltip allows you to toggle tooltips for the layer.

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.
• Display tooltip allows you to toggle tooltips for the layer.

Night / Day layer
