Dataset description

Caution: this version has been removed due to the license issue of FABDEM. Please do not use. You can access EDTM v1.1 or GEDTM from: EDTM v1.1: doi.org/10.5281/zenodo.7676373 GEDTM30: doi.org/10.5281/zenodo.14900180 Layers include: Ensemble Digital Terrain Model (EDTM) in 250-m resolution. Unit is in metre(m) and precision is in decimetre (dm). Maps are downscaled from 30-m resolution to 250-m in order to fit the size limit. We provide 30-m EDTM and its standard deviation as links: 30-m EDTM https://s3.eu-central-1.wasabisys.com/openlandmap/dtm/dtm.bareearth_ensemble_p10_30m_s_2018_go_epsg4326_v20230210.tif  Standard deviation https://s3.eu-central-1.wasabisys.com/openlandmap/dtm/dtm.bareearth_ensemble_std_30m_s_2018_go_epsg4326_v20230210.tif Derived using ALOS AW3D, GLO-30, MERITDEM, and national DTMs. We derived a  lower 10% quantile from all maps. In order to create bare earth data, we used canopy height (canopy height > 2m) and standard deviation (sd > 6m) to mask building and forest in AW3D and GLO-30. Practical processing is written here in Python. To access and visualize maps use:  OpenLandMap.org If you discover a bug, artifact or inconsistency, or if you have a question please use some of the following channels: Technical issues and questions about the code: https://gitlab.com/openlandmap/global-layers/-/issues  General questions and comments: https://disqus.com/home/forums/landgis/ All files internally compressed using "COMPRESS=DEFLATE" creation option in GDAL in Cloud Optimised GeoTiff (COG). File naming convention: dtm.bareearth = variable: digital terrain model (m), bare earth ensemble = determination method: ensemble of mutli-source dsm and dtm p10/std = aggregation/statistics method: 10th percentile / standard deviation 250m = spatial resolution / block support: 250 m, s = vertical reference: at surface, go = bounding box: global land without Antarctica epsg.4326 = ESPG code: epsg.4326 v20230210 = version code: creation date 20230210

Questions before production use

Practical answers on evaluation, licensing, freshness, versioning and support.

api.store is built and operated by Apitalks s.r.o. Company details and a direct contact path are linked in the footer for vendor checks and procurement review.
Yes. Selected APIs include a free API quota, so your team can validate coverage, freshness, response shape and workflow fit before asking for a production plan.
Often yes, but usage rights depend on the source license and dataset. We surface source, license and update metadata where available, and can help review terms before a production integration.
Maintained APIs include update metadata where available. For production integrations, we can add history, monitoring and push updates so changes are easier to detect and act on.
Production APIs can add SLA, stable identifiers, versioning support, history, push updates and direct support around the data your product or AI workflow depends on.
