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 reliable information on wind-resources, siting-data (such 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 - and also very efficient uncertainty analysis with gigabytes of data easily accessed.
• Trusted datasets: EMDAPI builds upon the trusted data-bases and data-sources that have been used through the online-data services in windPRO 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.

Data Model - Global Atlas Service

The EMD global-atlas-services is documented in a REST based API using the OpenAPI Specification. You can view the interfaces and download the interfaces as json or yaml, here. The service provides the following functionality:

• List Datasets: Full list of available datasets with their ID’s, descriptions and documentation liks (URL's).
• Locate Data-Nodes: Request locations of several nearby data nodes from a specific dataset given a latitude-longitude location.
• Place Order: Time-series data for any location whith any dataset (from latitude-longitude location). You can decide which period to download.
• Order Status: Request progress for an order - and recieve the download URL for the order.
