A small example of a network with OpenStreetMap in the background. OpenStreetMap maps are available under an open licence, so WaterSums can display these maps without any extra licence fees or complexity. We satisfy the compliance requirements by including in the background map an acknowledgement of the OpenStreetMap contributors and their valuable work. CloudMade maps are also supported, but these have different licensing and you will require a CloudMade API key. Depending on your usage, this may involve an additional cost.
Please note that WaterSums does not provide any bundled mapping licence or map data in the licence fee – if you wish to display background maps, you or your employer will need to satisfy the licensing requirements of the map providers.
