Elevation API

Seamless, accurate elevation & bathymetry data at your fingertips

Access high-quality, global elevation and bathymetry data through one API, from mountain peaks to the ocean floor.

A direct replacement for the Google Elevation API, with a free trial to get started.

Why choose the Elevation API?

Google API compatible

Drop-in replacement for the Google Elevation API: same request structure, easy migration.

Comprehensive coverage

Global elevation and bathymetry data from reliable, openly published sources.

Seamless integration

Simple REST endpoints and an API key: minimal setup, maximum efficiency.

High precision & accuracy

30 m digital elevation models on land, read directly from the source data.

Global reach

From peaks to ocean floors, all through a single API endpoint.

Cost-effective

Lower pricing than the big providers, with a free trial. See pricing.

Lightning fast

Rapid response times for all your elevation queries.

High capacity

Up to 600 points per request, more than the Google Elevation API allows.

Data sources

Every point is answered from the best available source for its location, drawing on established global datasets such as those below. We're continually improving coverage and accuracy by adding new elevation and bathymetry sources.

Each result's resolution field tells you which source it came from.
