AI-generated Key Takeaways
-
The
intersects()
method determines if two geometries share any points in common, returning true if they do and false otherwise. -
It can be applied to LineString geometries and accepts a second geometry as input for comparison.
-
Optional parameters include
maxError
for reprojection tolerance andproj
to specify the projection for the operation. -
The provided examples demonstrate the usage of
intersects()
with JavaScript and Python APIs in Earth Engine.
Usage | Returns |
---|---|
LineString.intersects(right, maxError, proj) | Boolean |
Argument | Type | Details |
---|---|---|
this: left | Geometry | The geometry used as the left operand of the operation. |
right | Geometry | The geometry used as the right operand of the operation. |
maxError | ErrorMargin, default: null | The maximum amount of error tolerated when performing any necessary reprojection. |
proj | Projection, default: null | The projection in which to perform the operation. If not specified, the operation will be performed in a spherical coordinate system, and linear distances will be in meters on the sphere. |
