HALOWERK Central Land – Austria Surface Elevation

Choose this endpoint when you need a precise, bilinearly interpolated surface elevation value for a specific point coordinate within Austria using the Copernicus DEM GLO-30 dataset. It is ideal for applications requiring sub-pixel accuracy in terrain height lookups (e.g. route planning, flood modeling, construction feasibility) specifically within Austrian boundaries. The built-in coordinate validation against the Natural Earth Austria boundary ensures you are not charged for out-of-scope queries. Prefer alternatives if you need elevation data outside Austria, elevation profiles along paths, or other terrain derivatives (slope, aspect, roughness) — sibling endpoints on the same host cover those needs.

• Coordinate outside Austria boundary — request rejected before payment with an error indicating the point is outside the supported region
• Latitude or longitude outside the published European coverage range (lat 34–72.5, lon -31.5–40.5) — validation error
• Malformed request body or missing required fields — 400-level error
• Payment failure or insufficient USDC balance — transaction rejected
• Temporary service unavailability — 5xx error
