Both use polygon center smallestOuterCircleRadius() - calculate the smallest outer circle (simple version) largestInnerCircleRadius() - calculate the smallest inner circle (simple version) // Each method creates a clone. Polygon is immutable expand(10) - create an expanded (inflated) polygon by x meters (negative values will deflate the polygon) movedClone($distance,$bearing) - create a moved copy of the polygon simplify($distance,$highQuality)- create a simplified polygon by removing coordinates but keeping shape makeCombined(Polygon $add) - add a polygon, create a connection between both (for converting multipolygons) makeWgsFromRd() - convert polygon to Wgs84 ``` ### Health Score 36 — LowBetter than 82% of packages Maintenance42 Moderate activity, may be stable Popularity18 Limited adoption so far Community7 Small or concentrated contributor base Maturity64 Established project with proven stability Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
