Class: GeodesicResampler
Resamples projected geodesic (great-circle) paths between defined endpoints into series of straight line segments.
Constructors
constructor
• new GeodesicResampler(minDistance, dpTolerance, maxDepth): GeodesicResampler
Constructor.
Parameters
| Name | Type | Description |
|---|---|---|
minDistance | number | The minimum geodesic distance this resampler enforces between two adjacent resampled points, in great-arc radians. |
dpTolerance | number | The Douglas-Peucker tolerance this resampler uses when deciding whether to discard a resampled point during the line simplification process. |
maxDepth | number | The maximum depth of the resampling algorithm used by this resampler. The number of resampled points is bounded from above by 2^[maxDepth] - 1. |
Returns

Properties
dpTolerance
• Readonly dpTolerance: number

maxDepth
• Readonly maxDepth: number
The maximum depth of the resampling algorithm used by this resampler. The number of resampled points is bounded from above by 2^[maxDepth] - 1.

src/sdk/geo/GeodesicResampler.ts:31
minDistance
• Readonly minDistance: number

Methods
resample
▸ resample(projection, start, end, handler): void
Resamples a projected geodesic (great-circle) path.
Parameters
| Name | Type | Description |
|---|---|---|
projection | GeoProjection | The projection to use. |
start | LatLonInterface | The start of the path. |
end | LatLonInterface | The end of the path. |
handler | GeodesicResamplerHandler | A function to handle the resampled points. The function is called once for each resampled point, in order. |
Returns
void
Throws
Error when the start and end of the path are antipodal.
