Getting real time ships locations between two different time periods

[Pradip Neupane]

Hi,

I  am using your API vessel-location-controller to get the real time data of the ships locations.

I want to extract all the ships location for 1 hr period between June 20, 2018 10:00:00 AM - June 20, 2018 11:00:00 . And these are milliseconds timestamp for those periods

1529478000000

1529481600000

I use the link as suggested in https://meri.digitraffic.fi/api/v1/metadata/documentation/swagger-ui.html#!/vessel45location45controller/vesselLocationsByTimestampUsingGET

And this is my link to extract data of those time periods

https://meri.digitraffic.fi/api/v1/locations/latest?from=1529478000000&to=1529481600000

When I do that, I get results but only of very few ships location on those period of time.

Arent there supposed to many ships during those time.

For example I  should also get multiple information of same ships travel location in that given time. But That API links gives very few information and if it gives, there is no multiple locations of the individual ships in that period time.

Can you please help me, what I am doing wrong and what else I need to make it work ?

Hi

Thanks for your message.  Currently we don't save the history of the locations and the API only returns the latest location per vessel.  

To list all the latest locations per ship, use this:

https://meri.digitraffic.fi/api/v1/locations/latest

Adding from and to parameters, it will get the same list but return only the latest locations with timestamps between from and to:

https://meri.digitraffic.fi/api/v1/locations/latest?from=1529478000000&to=1529481600000

So, this will not give you history between from and to, or the latest location between from and to.  It will give you the vessel's location only if it did happen between from and to.

I hope this answered your question, please do not hesitate to contact us.
