Terrain elevation sources and attribution

Scribble Maps uses elevation data to display terrain shading, elevation tint and contour lines. The source detail varies by location. A contour interval is the distance in elevation between lines. It does not describe the accuracy or grid spacing of the original elevation data.

Processing and modifications

Scribble Maps hosts elevation tiles built from a combination of public elevation sources. Scribble Maps selects available tiles, resamples elevation values when needed, and generates contour lines and labels for display. These outputs are modified or derived products. They are not the original elevation files.

Source credits and licences

The credits below identify the original information providers. Each link leads to the provider or source information. The licence links lead to copies of the source notices hosted by Scribble Maps. Credits are grouped by provider and licence rather than by elevation dataset.

The source references and licence documents on this page were checked on 5 October 2026.

Required source notices

Terrain and contours produced using Copernicus WorldDEM-30 © DLR e.V. 2010-2014 and © Airbus Defence and Space GmbH 2014-2018 provided under COPERNICUS by the European Union and ESA; all rights reserved.

Outputs using Japanese elevation data are created by editing elevation information from the Geospatial Information Authority of Japan. The source records include GSI use approval R 8JHs 131 for that material. This reference identifies the upstream approval and does not represent a separate approval issued to Scribble Maps. See the GSI terms of use.

Reusing source data

The sources have separate licences. This page does not replace those licences or grant additional permission. If you reuse elevation data or distribute derived products, check the terms for the sources involved and retain the applicable credits and notices. Linking to this article does not by itself confirm that every reuse meets every source condition.
