Open-source attributions

Last updated: 2026-10-04

Software dependencies

Mantle Place stands on a deep stack of open-source software. The list below covers the top-level production dependencies whose licenses require attribution. Transitive dependencies inherit attribution through their parents. Source code for each project lives at the linked repository.

Data sources

See the Licensing page for the full Produced Works architecture and per-order attribution that ships in every bundle. The sources below seed every order. The record holders behind public-record layers are named by layer, state and jurisdiction on the System Status page:

  • Protomaps planet basemap · ODbL (rendered output qualifies as Produced Work). Sovereign navigational basemap + per-order rasterized basemap tiles.
  • OpenStreetMap · ODbL. Upstream feature source for Protomaps and Overture. © OpenStreetMap contributors.
  • Overture Maps Foundation · ODbL (OSM-derived themes). Building footprints and structured vector layers (buildings, roads, water, land use, land cover). © Overture Maps Foundation, © OpenStreetMap contributors.
  • NAIP (USDA aerial imagery) · US public domain. US aerial imagery at 1 m or finer, served via Microsoft Planetary Computer.
  • Sentinel-2 L2A (ESA Copernicus) · ESA Free & Open Data (Copernicus Sentinel data). Global 10 m satellite imagery for areas outside NAIP coverage, served via Microsoft Planetary Computer. Contains modified Copernicus Sentinel data.
  • Mapterhorn Terrarium-RGB · CC-BY (Copernicus DEM + regional DEMs). Global terrain tile distribution wrapping Copernicus GLO-30.
  • USGS 3D Elevation Program (3DEP) · US public domain. Elevation for orders in the continental US, fetched directly from USGS: the 1 m lidar DEM where it covers the site, otherwise the 1/9 or 1/3 arc-second DEM. Credit: U.S. Geological Survey, 3D Elevation Program.
  • ESA WorldCover 2021 v200 · CC BY 4.0. Land cover classes on every order. © ESA WorldCover project. Contains modified Copernicus Sentinel data (2021).
  • Meta and WRI global canopy height · CC BY 4.0. Tree canopy height and tree points on every order. Tolan et al., "Very high resolution canopy height maps from RGB imagery".
  • FEMA National Flood Hazard Layer · US public domain. Flood zones on US orders, passed through as FEMA publishes them. The effective FIRM panel named in the bundle manifest is the authority.
  • Esri World Imagery (ArcGIS Location Platform) · Esri ArcGIS Location Platform Agreement (proprietary; view only). The curator globe’s optional Satellite view only: streamed to your browser, never part of a bundle. Powered by Esri; the imagery’s contributors are credited live under the globe.
  • Photon (komoot) · Apache-2.0 (software); search data ODbL via OpenStreetMap. The curator’s place search only: turns a typed place name into a point on the globe, and is never part of a bundle. © OpenStreetMap contributors.
  • GeoNames · CC BY 4.0. The curator’s place search only: corrects a misspelt place name against GeoNames populated places (cities5000), and is never part of a bundle. Data from GeoNames.org, licensed under CC BY 4.0.
  • Copernicus DEM GLO-30 · Copernicus WorldDEM-30 licence. Underlying global elevation source; elevation delivered through Mapterhorn is adapted from it.
