Vietnam - Electricity Transmission Network

This data has been prepared for a World Bank project and represents the existing transmission lines, substations and power stations as of 2016.
This data was obtained in a 2 phase process:
1. geo-reference of PDF map
2. digitization of transmission network
Due to the quality of the PDF map, the geo-referencing process resulted in isolated horizontal and vertical displacements of 2 to 10 km; the final product contains only the rough location of the network elements and it is not suitable for applications requiring high accuracy data.
