Flow Matrix Analysis

The Flow Matrix API calculates a statistics of origin and destination between all defined regions. It also provides all via waypoints for all origin and destination pairs.
Each region in the input is treated as origin, destination and a "Via" region at the same time.
This is simplify result you get for 3 regions A, B and C defined.

This API is asynchronous. There are some important notes about using this API:

  • The latitude and longitude coordinates are in EPSG4326 / WGS84 format for both input and output. Other coordinate systems are not supported.

  • The maximum supported region area sum in total is 3000 km^2 Requests with bigger region area sum will be rejected.

  • The maximum number of regions is 200.

  • The maximum number of date ranges is 4.

  • The maximum number of time ranges is 4.

  • As the service is asynchronous it can take a while before results are available, depending on how busy the service is. Do not repost your request multiple times if you do not get feedback within seconds, we will ensure that the results are delivered.
