Before using these data sources, users must review the terms and conditions on the websites of the respective organisations and contact them directly for any clarifications or questions.

It is the sole responsibility of the user to review the terms and conditions for all the above sources prior to using the data. TransitionZero makes no claims or warranties regarding the accuracy, completeness or licensing terms for these datasets.

4. Data Accuracy

The models based on earth observation and machine learning are continually evolving, and are expected to be updated over time and TransitionZero is not responsible for any reliance thereon.

TransitionZero endeavours to ensure that the TZ-SAM dataset is accurate. However, such TZ-SAM data has been (1) modelled using data from third-party sources that are publicly available, or (2) collected from publicly available sources. TransitionZero has no control over any aspects of such data, including its accuracy, timeliness, completeness or consistency.

Users of the TZ-SAM data are advised to exercise caution and evaluate the methodology, data sources, and limitations of the TZ-SAM data. Users are encouraged to contact TransitionZero through info@transitionzero.org in case of any questions or if any errors are identified.

The information made available via TransitionZero is on an “as is” and “as available” basis without any warranty of any kind.

TransitionZero did not select and does not endorse the geographic boundaries, names, and regions shown on maps and in lists, tables, documents, and databases on TZ-SAM. All such information was made using Natural Earth: https://www.naturalearthdata.com/

5. Indemnity

You agree to indemnify, defend and hold harmless TransitionZero Ltd, its officers, directors, employees, consultants, agents, suppliers from any and all third party claims, liability, damages and/or costs including, but not limited to any problems arising from your use of TZ-SAM or your violation of this Agreement.
