🗻 Open Topo Data Elevation Scraper

🚀 Look up ground elevation for any list of coordinates in seconds. Pull terrain altitude in meters from 11 global elevation datasets including SRTM 30m, NED 10m, EU-DEM 25m, ASTER 30m, ETOPO1, GEBCO 2020 bathymetry, Mapzen Terrarium, and more. Send a batch of lat/lng pairs, get back elevation, dataset name, and grid resolution per point.

The Open Topo Data Elevation Scraper turns a list of {lat, lng} points into a clean dataset of elevations sampled from world-class open Digital Elevation Models (DEMs). It pulls from Open Topo Data, a self-hosted open service that wraps NASA SRTM, USGS NED, ESA Copernicus, NIWA, GEBCO, ETOPO, and other public DEMs into a single uniform interface. The Actor returns 7 clean fields per point: latitude, longitude, elevation in meters, dataset name, grid resolution in meters, interpolation method, and a timestamp.

Coverage is global. Pick SRTM 30m for worldwide land coverage, NED 10m for the United States, EU-DEM 25m for Europe, NZDEM 8m for New Zealand, GEBCO 2020 for ocean bathymetry, or ETOPO1 for a coarse but worldwide land + sea model. Each batch is delivered with the dataset attribution and the underlying grid resolution so downstream pipelines know exactly which model produced each number.

🎯 Target Audience	💡 Primary Use Cases
GIS developers, drone planners, hiking & outdoor apps, flood-risk analysts, civil engineers, route planners, weather modellers, environmental scientists	Drone mission elevation profiles, hiking trail gain charts, flood-risk overlays, line-of-sight calculations, watershed analysis, bathymetric route planning

📋 What the Open Topo Data Elevation Scraper does

One precise workflow with eleven dataset choices:

• 📍 Batch elevation lookup. Send up to many thousands of coordinates per run, get back elevation per point.
• 🌐 Eleven open elevation models. SRTM 30m, SRTM 90m, ASTER 30m, NED 10m, NZDEM 8m, EU-DEM 25m, Mapzen Terrarium, EMODnet 2018 bathymetry, GEBCO 2020 bathymetry, ETOPO1, BKG 200m.
• 🧮 Three interpolation modes. Bilinear (default), nearest-neighbour, or cubic for smoother results at off-grid coordinates.
• 🪪 Dataset attribution. Every record records the dataset that produced the elevation, plus the grid resolution.
• 🚦 Polite rate-limit handling. The Actor respects the public service's published rate limit and backs off automatically on 429s.

💡 Why it matters: elevation is the single most-requested attribute for outdoor routing, drone path planning, and flood modelling, but stitching together the right DEM for each part of the world is a project in itself. This Actor gives you eleven trusted public models behind one consistent record shape.

📊 Data fields

Each record includes: dataset, elevationMeters, interpolation, latitude, longitude, resolutionMeters, scrapedAt. These field names come straight from the actor's dataset schema, so what you see here is what lands in your dataset.
