Foursquare Studio Panel

The Foursquare Studio Panel Plugin enables you to add Unfolded Studio Maps to your Grafana dashboard.

Features

• Visualize your geospatial data in your Grafana dashboard as:

  • Points on the map
  • A line (LineString) that connects the points based on the passed timestamp
  • TripLayer that allows you to animate the received data based on the passed timestamp
  • A GeoJSON layer

• Save your map configuration in the Grafana instance so you don't lose your map settings when the data refreshes.

• Save your map in the Foursquare Cloud at any time with the data from the Grafana queries

Installation

See https://grafana.com/docs/grafana/latest/administration/plugin-management/#install-a-plugin for help with the installation process.

Supported version of Grafana is 7.0+

Usage

Displaying data as Points on the map

Visualizing the data as Points on the map doesn't require any time field only the location. You need to provide the values for the latitude and longitude values and you need to name these values exactly like that in the query. The order of the properties isn't important.

An example of a query for getting the latitude and longitude against a PostgreSQL (with PostGIS) database:

SELECT long AS longitude,
    lat AS latitude
FROM table_name

For example it would be a similar query if you are using the geometry data type in PostGIS:

SELECT ST_X (ST_Transform (geom, 4326)) AS longitude,
   ST_Y (ST_Transform (geom, 4326)) AS latitude
FROM table_name

If you want to visualize more properties in the tooltip of the created points, you just need to add that data to the query:

SELECT ST_X (ST_Transform (geom, 4326)) AS longitude,
       ST_Y (ST_Transform (geom, 4326)) AS latitude,
       name,
       borough,
       date_created as time
FROM nyc_subway_stations

Display a line that connects the points based on the passed timestamp

Similar to the creation of Points, to create a line that connects the points you need to provide the time value (as Unix timestamp) in the ascending order for the respective row. Keep in mind to name the properties in the query as latitude, longitude and time.

To show the line you need to toggle the Create line path from points to true in the panel options.

SELECT ST_X (ST_Transform (geom, 4326)) AS longitude,
       ST_Y (ST_Transform (geom, 4326)) AS latitude,
       date_created as time
FROM nyc_subway_stations
ORDER BY time

Animate the data using the TripLayer

If you want to leverage more advanced features of Unfolded Studio you can animate the time-based data by toggling the Enable animation to true in the panel options. To enable this option, Create line path from points must be set to true in the panel options. Same query as in the line creation should be provided.

This will create a TripLayer on the map and add a timeline animation control on the map. To customize this control see our official documentation.

SELECT long AS longitude,
   lat AS latitude,
   date_created as time
FROM nyc_subway_stations
ORDER BY table_name

Display a GeoJSON object

If you are able to leverage your database to get a single GeoJSON object, you can provide it to the plugin to be displayed on the map. Keep in mind to name the value as geojson_layer.

An example of a query for getting the GeoJSON LineString object against a PostgreSQL (with PostGIS) database:

SELECT ST_AsGeoJSON(ST_MakeLine(ST_Transform(geom, 4326) ORDER BY date_created)) AS geojson_layer
FROM table_name

An example of a query for getting the custom GeoJSON feature object with selected properties against a PostgreSQL (with PostGIS) database. This query will include all properties except for gid, geom values. Keep in mind to name the value as geojson_layer.

SELECT jsonb_build_object(
 'type',     'FeatureCollection',
 'features', jsonb_agg(features.feature)
) as geojson_layer
FROM (
SELECT jsonb_build_object(
 'type',       'Feature',
 'id',         gid,
 'geometry',   ST_AsGeoJSON(ST_Transform(geom, 4326))::jsonb,
 'properties', to_jsonb(inputs) - 'gid' - 'geom'
) AS feature
FROM (SELECT * FROM nyc_subway_stations) inputs) features;

In case you have a GeoJSON object for each individual Point in the row, you can just create a simple query as when you are creating a regular point, just provide the geojson instead of the latitude and longitude values. In this case name the property value as geojson and not as geojson_layer.

SELECT ST_AsGeoJSON(ST_Transform(geom, 4326)) AS geojson
FROM nyc_subway_stations

Save your Map Configuration

Any changes made in Unfolded Studio (layers, filters, interactions, base map settings) can be saved in your Grafana instance, and they will be applied when the plugin is initialized. For example if you changed the Base Map Style from Dark to Light and you want to save that setting you need to:

1. Click the Save button under the Save map configuration section

2. Apply that change with clicking Save in the top right corner of your Grafana panel settings to confirm your changes

Save Grafana Maps to your Foursquare Cloud Account

In case you want to save and share maps visible in your Grafana Panel, you have the ability to save a map (along with any data from the panel's queries) to your Unfolded account.

Required steps to save your map:

1. Log in to your account in Unfolded Studio
2. Copy your Access Token

3. Go to your Foursquare Studio Panel Plugin settings
4. Click on Save map to Foursquare Cloud button
5. Paste the token in the Add Access Token field
6. Optionally you can also add map name and description values

If the request is successful you will get the saved map URL at the bottom of the section.

Keep in mind that the created map is still private and you would have to publish it in Unfolded Studio to be able to share it publicly.

Add multiple queries

Plugin allows you to add multiple queries where the result of each query will be added as a separate dataset and layer in the Foursquare Studio Panel.
