Terms of use

Documentation and evaluation

The landing page, API documentation and Playground support product discovery and evaluation. The public demo key is for evaluation within the service’s access scope and limits.

Production integration

APIs, deployment area, traffic, access rights, support terms and production key provisioning are agreed according to application requirements.

Specialist datasets, delivery methods, copying or redistribution rights and commercial conditions are defined in the relevant agreement. Product information does not replace a service agreement.

Data scope and interpretation

Parcel and planning data support lookup, investigation and comparison. For a specific decision, check the dataset version and relevant documents from the responsible authority.

Routing and reachable-area results depend on inputs, configuration and source data. Coordinate conversion requires the appropriate reference systems, projection parameters and coordinate order.

Sources and attribution

Use of each map layer and dataset follows the rights provided and its applicable attribution requirements.

The Da Nang scene includes GMap and Microsoft Global ML Building Footprints. Most building heights are illustrative.
