TerrainTap Fast Elevation API delivers high-resolution global terrain data with exceptional speed and reliability. Designed as a drop-in replacement for the Google Elevation API, it provides seamless compatibility while offering significantly faster performance and lower operational cost.
Our data backbone is the Copernicus GLO-30 dataset, offering 30-meter resolution for nearly all terrestrial regions on Earth. In the rare cases where GLO-30 is unavailable, the system automatically falls back to the GLO-90 dataset to maintain complete, gap-free coverage of all land surfaces.
Built from the ground up for performance, this service runs on a custom backend optimized for modern hardware. The architecture minimizes overhead and maximizes throughput by running close to the metal. A spatially-aware caching layer intelligently manages a multi-terabyte dataset, prioritizing high-demand geographic regions and keeping relevant data in RAM for lightning-fast response times—even under heavy load.
Whether you're building a GIS system, powering a mapping application, or delivering location-based services, Fast Elevation API provides the performance, reliability, and precision you need—globally.

No long-term commitment. Upgrade, downgrade, or cancel anytime. Free Trial includes up to 50 requests.
The elevation endpoint returns elevation data for specified GPS coordinates. Each response includes the elevation value, the geographic location (latitude and longitude), and the resolution of the data in meters.
The key fields in the response data include "elevation" (the height above sea level), "location" (with latitude and longitude), and "resolution_meters" (indicating the data's precision).
The response data is organized in a JSON format. It contains a "results" array with individual elevation data points, and a "status" field indicating the success of the request.
The elevation data covers nearly all terrestrial regions on Earth, utilizing the Copernicus GLO-30 dataset for high-resolution data, with fallback to GLO-90 in areas where GLO-30 is unavailable.
The elevation endpoint accepts GPS coordinates as parameters. Users can specify one or multiple sets of coordinates to retrieve corresponding elevation data for each location.
Data accuracy is maintained through the use of high-resolution datasets like GLO-30 and GLO-90, along with a custom backend optimized for performance, ensuring reliable and precise elevation data.
Typical use cases for the elevation data include GIS applications, mapping services, outdoor navigation tools, and any location-based services requiring accurate terrain information.
Users can utilize the returned data by extracting elevation values for analysis, integrating them into mapping applications, or using them to enhance location-based services, ensuring they account for the resolution and geographic context.
To obtain your API key, you first need to sign in to your account and subscribe to the API you want to use. Once subscribed, go to your Profile, open the Subscription section, and select the specific API. Your API key will be available there and can be used to authenticate your requests.
You can’t switch APIs during the free trial. If you subscribe to a different API, your trial will end and the new subscription will start as a paid plan.
If you don’t cancel before the 7th day, your free trial will end automatically and your subscription will switch to a paid plan under the same plan you originally subscribed to, meaning you will be charged and gain access to the API calls included in that plan.
The free trial ends when you reach 50 API requests or after 7 days, whichever comes first.
No, the free trial is available only once, so we recommend using it on the API that interests you the most. Most of our APIs offer a free trial, but some may not include this option.
Yes, we offer a 7-day free trial that allows you to make up to 50 API calls at no cost, so you can test our APIs without any commitment.
Zyla API Hub is like a big store for APIs, where you can find thousands of them all in one place. We also offer dedicated support and real-time monitoring of all APIs. Once you sign up, you can pick and choose which APIs you want to use. Just remember, each API needs its own subscription. But if you subscribe to multiple ones, you'll use the same key for all of them, making things easier for you.
