I am in the process of trying to use a latitude and longitude value (of an image) to estimate it’s height via a global digital elevation model.
The use-case; I want to create elevation profiles of my Mapillary sequences (I don’t want to use the sensor reported elevation – it is corrupt).
I can’t afford Google Maps money (1,000 lookups = $5 USD). I have close to 1 million images. I don’t have $5k.
Does anyone know of any free services (or ones with a generous free tier) that expose their data via an API and could be used for this purpose?
