HALOWERK Central Land – Slovakia Drainage Tendency

Choose this endpoint when you need a terrain-derived, slope-and-ruggedness-based drainage or runoff tendency score specifically for a coordinate within Slovakia. It is pre-validated against Slovak boundaries so out-of-country calls are rejected cheaply. Prefer it over generic elevation or slope APIs when the output needed is specifically a runoff tendency index rather than raw elevation or gradient.

• Coordinate outside Slovakia boundary — rejected with a geographic validation error before payment
• Coordinate within European coverage range but outside Slovakia — validation failure
• Latitude or longitude out of published European range (34–72.5N, -31.5–40.5E) — schema validation error
• Missing latitude or longitude parameter — request error
• Ambiguous terrain at coordinate edge of coverage — possible null or low-confidence output
