EMD-API - Global Atlas Services

Introduction

The Global Atlas Services is available from the EMD-API: It is a service created in order to provide an interface (REST/OpenAPI standard) to atlas-data on wind-resources, siting-data (such as site flow characteristics), geospatial-predictors and elevations. The service delviers a unitified interface to a wide range of atlas data, and has the following key features:

• Instant data delivery: All datasets within the EMDAPI are ready processed and requests are served within seconds or minutes
• Hundreds of atlas parameters for renewable energy: EMDAPI provides access to hundreds of parameters on winds, siting, elevations and other geospatial parameters used within renewable energy
• Unified interface: The unified interface which allows for integration to internal processes and tools
• Trusted datasets: EMDAPI builds upon the trusted data-bases and data-sources is also used through the online-data services in windPRO, some for more than a decade.
• Built on open standards: EMDAPI is a REST based service that implements the OpenAPI standard].
• Available from any development tool: Access to the climate databases is available from your preferred development platform - C#, R, python, html, java, php, scala and swift. Just use the OpenAPI tools to generate the client software for your preferred platform.
