Online Distance Tables Subscription

Setting up a subscription with AtoBviaC Ltd is free* and easy to do.

* A subscription can be created free of charge to "demo" the software. A demo subscription can use all of the features of the full Online Distance Tables, but is limited to calculating distances between just 6 ports: Chiba, Copenhagen, LOOP Terminal, Melbourne, Novorossiysk and Port Rashid. A demo subscription can be upgraded to a full subscription with the purchase of a block of Online Distances.

What does a subscription consist of?

•Access keys for our tools. Every subscription will have a "demo" access key. Once you have purchased a block of distance calculations you will also have a "live" key which removes all the restrictions from the software.

•The ability to purchase and top up blocks of distance calculations for use with the tools published by us or third parties.

What are the available tools?

The Online Distance Tables: an online application implemented in Microsoft Silverlight, allowing access to the Distance tables from a compatible web browser. This includes most web browsers for Windows, and Safari on Mac.

Due to the age and unsupported status of Silverlight, some web browser software vendors have recently begun cutting support for the technology. If this applies to your chosen web browser, then unfortunately you will need to access the Online Distance Tables using another browser (on Windows you can use Internet Explorer; on Mac you can use Safari). Please be assured that we are working on updating the Online Distance Tables to newer technology.

The AtoBviaC Web Service: a fully functional web service, designed to allow third parties to build applications that incorporate the distance tables. The screen shot below is of the Demo application, which is supplied on request (including the source code).

What are Distance Calculations and how to we manage these?

A Distance calculation is made and 1 distance is deducted from your subscription total when the following conditions are met:-

1.Immediately after logging in with a 'live' access key when you first calculate a distance between any of the ports in the tables using any of our tools.

2.When a subsequent calculation uses a different port pair than the previous calculation. You can vary the route between the same two ports without charge so long as the port names do not change.

The available distance count is for your subscription and is independent of the number of users that have access to the subscription. Thus you can have a number of users accessing the Silverlight version and a number of users accessing the Web Service through custom software. Any of these users may cause the count of available distances to decrease by 1 when they calculate a distance, based on the rules above.

All of the products will stop working when your number of distances available reaches zero. You can purchase more distances at any time. Distances are available in blocks of 1000, 2500, 5000, 10000, 25000 and 50000; discounts apply when buying larger blocks.

Any block of distance calculations purchased is valid for 1 year. The available distance count will be reset to zero exactly 1 year after you last made a purchase of a block of distances, unless exceptional circumstances apply.

What information is stored and accessible through a subscription?

Apart from the usual contact information the following information will be contained in your subscription:-

Live AtoBviaC Access Key	The unique access key for your Subscription, that unlocks all the functionality in the tools.
