Conversion explorer Choose a source geometry, a resolution, a containment rule, an execution target, and platform constraints. The explorer recommends a documented conversion method, classifies its approximation, flags expected risks, and computes a live H3 example in your browser (h3-js). Recommendations are defaults for the stated intent — not universal truths.

Circle radius 550 m is below Generic point-radius DSP's minimum radius (1000 m) — coarsen the resolution or merge cells. Intersect mode overreaches at boundaries and overlaps neighbouring polygons. Recommendations are defaults for the stated intent, not universal truths. Always confirm against the platform's current API.
