Filtering
MapWeave can handle up to 1 million data points while retaining real-time performance. However, in order to extract specific narratives it can be helpful to filter the data, by time, location and more.
Filtering by Time
MapWeave provides a simple timeFilterRange API to only display items within a specific time period for both the network and observations layers.
Useful APIs
- NetworkLayerOptions
timeFilterRange - ObservationsLayerOptions
timeFilterRange
Here you can see the path of Hurricane Rafael in November 2024. A simple html
input is used with MapWeave to control the timeFilterRange in the observations layer, use the slider to filter the observations to the dates shown.
Open the example in the playground and see the code.
MapWeave can also be integrated with the Keylines Time Bar or KronoGraph for more complex filtering.
