# Murmurations Map
When a Node posts a Profile to the Index and has geolocation coordinates (i.e., latitude and longitude) included in its profile, it wil be plotted on the map. The synchronization between the map and index take place every minute.
Use the search options and URL parameters explained below to create custom map views of geolocated data in Murmurations.
# Search Options
# Schema
Select a schema if you want to narrow down the results to nodes whose profiles are based on a specific schema. The default is to show all nodes in Murmurations ("all schemas").
# Tags
Search for nodes who have one or more tags associated to their profiles. For example: bio, demeter will return a list of nodes with either of these tags in the profile. Searching for demeter will only return nodes with that tag.
The tag search uses fuzzy matching, which means spelling differences/mistakes and partial word matches are possible.
# Primary URL
The primary_url is usually the unique web address for an entity. For example, murmurations.network is the primary_url of the Murmurations project. Read this entry in the Schemas FAQ for more information about it.
Unlike with tags, the primary_url search is an exact match search. Typos and spelling mistakes will not be matched.
# Last Update Time
Use the date/time picker to specify the moment after which the nodes were last updated in the index. This is a good way to find new nodes that have been added to the index, or who made recent updates to their profiles.
# URL Parameters
# Search Parameters
All of the above search options have corresponding URL parameters. For example:
There are two additional parameters that can be specified with the tags parameter:
tags_exact(trueorfalse, default isfalse)tags_filter(andoror, default isor)
When tags_exact is true, only exact tag matches will be returned (fuzzy matching is disabled).
When tags_filter is and, only results that contain all of the listed tags are returned.
Compare:
https://map.murmurations.network/?tags=bio,demeter (opens new window)
To:
https://map.murmurations.network/?tags=bio,demeter&tags_filter=and (opens new window)
The latter returns significantly fewer results than the former.
# Localization Parameters
You can set tbe center point and zoom level of the map with the following parameters:
latlonzoom
For example, centering London:
https://map.murmurations.network/?lat=51.513853&lon=0.098354&zoom=10 (opens new window)
And Berlin:
https://map.murmurations.network/?lat=52.517038&lon=13.377040&zoom=11 (opens new window)
# Controlling data size with the range parameter
With over 30,000 nodes in the index, it can take some time to load and then render them all on a map in a browser. See this discussion post (opens new window) for more details.
To narrow down the amount of data that loads and thus render the map faster, set a center point on the map using the localization parameters described above, but add an additional range parameter (e.g., 10km or 6mi).
Here is an example loading all index data in the Paris area:
https://map.murmurations.network/?lat=48.85&lon=2.35&range=10km&zoom=12 (opens new window)
And the Berlin example from above with the range parameter set to 5 kilometers:
https://map.murmurations.network/?lat=52.517038&lon=13.377040&zoom=11&range=5km (opens new window)
And 20 kilometers:
https://map.murmurations.network/?lat=52.517038&lon=13.377040&zoom=11&range=20km (opens new window)
Depending on the range you set, you will need to adjust the zoom level accordingly to show all of the data within that range.
# Hiding search parameter inputs
For a more compact view when you are embedding the map on your website or for mobile viewing, use the hide_search URL parameter.
