EMD Electrical Grid Map
Introduction to the EMD Electrical Grid Map
The EMD Electrical Grid Map is built upon the OpenStreetMap (OSM) project, with a specific focus on electrical grid data, which are typically hidden in standard map renderings. The data include many different types of data, e.g.: grid-lines, substations, wind-turbines, power-plants. To highlight this data, we mute the usual map colors and overlay the electrical grid elements. Where available, voltage levels are also displayed alongside the cable lines. The source data for this map comes from the OpenStreetMap (OSM) project, an open and editable map with global coverage, created and maintained by a dedicated community. For more information or to contribute to the project, please visit the OpenStreetMap homepage. Samples of two selected places in Denmark and Australia are shown in the figure below.
Legend
Power lines are split into 5 categories, shown at different zoom levels:
- Up to 1kV: Shown from zoom level 11 in dark grey
- Up to 35kV: Show from zoom level 11 in light green
- Up to 230kV: Shown from zoom level 5 in light purple
- Up to 500kW: Shown from zoom level 5 in dark purple
- High voltage DC: Shown from zoom level 5 in dark blue
Power cables under ground/water is drawn dashed.
- Substations are shown from zoom level 8 as a lightning symbol
- Wind Turbine parks are shown from zoom level 8 as a light grey polygon
- Individual turbines are shown a dots from zoom level 8 and as a turbine symbol from zoom level 12

Usage Notes
- Issue with mapping of disputed territories around the world (1):
EMD policies on the OSM dynamic map in windPRO is aligned with official OSM policies. Citation from OSM-website: "Currently, we record one set that, in OpenStreetMap contributor opinion, is most widely internationally recognised and best meets realities on the ground, generally meaning physical control. In areas without clearly defined borders, the line is approximate." Learn more at the OSM wiki: https://wiki.openstreetmap.org/wiki/Disputed_territories. - Issue with mapping of disputed territories around the world (2):
If it is not feasable for you to use the OSM-map based on actual in-situ conditons, such as if you need to use a map with your official national (claimed) borders or the interntional recognized borders: In this situation, we recommend to procure an official map from your national ordnance-survey or preferred map-provider. Then attach this map as a background map to windPRO. In windPRO it is very easy to add georefernced images and map-servers: see how in the BASIS manual (section 2.4, this is available from the windPRO knowledgebase).
