Self-hosted elevation service that works with the terrain data provided by Mapzen and Amazon AWS S3. You can either pre-download the entire data on your server (ca. 200 GB) or access directly on S3 (for minimal latency from us-east-1
region).
Try it out with our hosted service: https://elevation.racemap.com/api
Inspired by:
The service has a very simple API. Just post your latitude-longitude pairs as a JSON array to the service and receive an array of elevations as response. Maximum post payload is by default 700 KB (which fits roughly 10,000 points).
# > [[lat, lng], ...]
curl -d '[[51.3, 13.4], [51.4, 13.3]]' -XPOST -H 'Content-Type: application/json' http://localhost:3000
# < [ele, ...]
For one-off queries. You can also issue GET requests with latitude and longitude as query parameters.
curl 'http://localhost:3000/?lat=51.3&lng=13.4'
# < ele
Download data (ca. 200 GB):
