What is the difference between the Laminar Data Hub and the Laminar Data Private Platform?

The Laminar Data Hub is available to all of our approved subscribers whereas the Laminar Data Private Platform is dedicated to just you and your partners.

How do I get my data onto Laminar Data?

If your data is in a standard form such as AIXM, WXXM or FIXM we can use one of our standard Data Connectors. If your data is bespoke, we have off-the-shelf Data On-Ramping packages where we will build you a custom Data Connector, Data Validator and API. Contact us at for more details.

How long does it take to get my data onto Laminar Data?

If our team of engineers have worked with similar data before, then it’s simply a matter of days. If you have unique proprietary data, Contact us at to discuss.

How much does it cost to get my data onto Laminar Data?

If your data is being hosted on the Laminar Data Hub there could be no charge and the Data On-Ramping will be included in your subscription cost. However, if your data is being hosted on the Laminar Data Private Platform, we will work with you on the Data On-Ramping cost depending on the complexity of your data.

How is data managed in Laminar Data?

Data managed in Laminar Data flows through numerous stages: first it’s loaded through a Data Connector, then QA’d with Data Validators, then processed (conflated, fused, aggregated) with numerous Data Processors, then stored in the Persistence Layer. Finally, data is shared either via the Hub API or a Private API depending on which platform your data is on. The same flow applies to any data updates coming into Laminar Data.

How secure is my data?

Laminar Data is independently penetration tested, and we are actively working towards a number of accreditations, including ISO 27001 Information Security Management.

How do I access my data?

As part of our Data On-Ramping package you have the option of using an existing API or working with our engineers to design a custom API for your data. APIs can either be RESTful or based on SWIM standards.

How can I monetize my data on Laminar Data?

If we host your data on the Laminar Data Hub we do all of the heavy lifting, loading, geometry checking and API building. Through our API Management Layer we know how many times a subscriber has accessed your data, meaning we can pass a royalty back to you based on its use.

How are existing copyright / data licensing rights maintained?

Every piece of data in the Laminar Data platform has an owner, a source and a known quality. We always respect data ownership and copyright, and have strict rules for complex derived works and acceptable uses for certain data feeds.

What data is available on the Laminar Data Hub through the Hub API?

Currently we have global coverage of the following data: Flight Positions, Flight Plans, NOTAMs, METARs, TAFs, and Aerodromes, plus harmonized and value-added European coverage of Sectors, Routes, NAVAIDs and Designated Points. If there is something you need that we don’t have, please do contact us by sending an email to

How will I know when a new data source is made available?

We’re constantly adding new data sets and whenever we add a new one you’ll see it on the Snowflake Software website.

How have other people developed apps for this?

There are Laminar Data early adopters building some amazing apps, ranging from mobile apps to thick clients.

How reliable is the data? What is the data quality?

We make every reasonable commercial effort to assure the quality of the data coming into the Laminar Data platform. Our Data Validator checks both data in through the Data Connector and data out through the API. Unfortunately we are unable to make any formal assurance on the quality of the data, beyond what is declared by our Data Providers, because it is out of our direct control.

What guarantee do you supply that the data is up-to-date?

We make every reasonable commercial effort to ensure that the data is up-to-date, but unfortunately we cannot provide any guarantees as we are reliant on our Data Providers feeding us the updated data. All data is time stamped and the refresh cycles are published along with the APIs.

Is the data guaranteed? Is it endorsed by any authority?

There are no guarantees with the data and it is not endorsed by any authority. Our Terms of Service and End User Licence Agreement (EULA) includes the respective terms and conditions for each Data Provider.

Is there a Dev kit, how do I use it?

We love using javascript frameworks like Leaflet and Openlayers for browser-based apps. Client systems can use standard software development frameworks or tools such as GO Loader Aviation.

How long do you offer evaluation periods for?

We offer a 14 day trial of the Laminar Data Hub Service to new users. Trial limited to 5,000 hits per day for the duration of the trial period. In order to keep using the service beyond the trial period, and find out our pricing bands, please contact us via email

Are there any demonstration apps to get me started?

We’re working hard on building some, and our early adopters have some amazing things in the pipeline. They will be available shortly; watch this space.

Where is the best place for me to start developing?

Head over to and log in, then you can use our ActiveDocs to try out the API and review the responses.
