Skytap Subscription

Skytap Service

Marta Systems’ SKYTAP(sm) Weather Data Service is a multi-tiered subscription service which delivers all types of weather data to your Yosemite system over the Internet using a secure, proprietary data transfer protocol.

Service Overview:

SKYTAP(sm) is one of the many weather data sources that is compatible with our Yosemite meteorological software suite. SKYTAP’s unaltered raw data can also be used with your own application.

You select which data you need, and how often to retrieve it, and your system stays automatically updated with the latest available weather data without any further intervention. Data transfer occurs at high speed using lossless data compression.

SKYTAP(sm) reliability is assured through our implementation of redundant servers, data sources, multiple separate high-speed internet connections, 24-hour monitoring and alerting systems, and redundant backup power systems.
