Remove points near endpoints of a linestring

This function removes points from a set of points that are within a specified tolerance distance of the start or end point of a linestring.

Usage

remove_points_near_endpoints(points, linestring, tolerance = 0.01)

Arguments

points

A sfc object containing points to filter.

linestring

A linestring object.

tolerance

A numeric value representing the maximum distance from the line's ends to consider points for filtering. Points within this distance will be excluded.

Value

A sfc object containing the filtered points.

Examples

# Create a points
points <- create_points(
  0.000, 1.000, 0.500, 0.600, 1.000, 0.010, 1.500, 0.501, 2.000, 0.990
)

# Create a linestring
linestring <- create_linestring(0, 1, 1, 0, 2, 1)

# Plot the points
plot(linestring, col = "gray")
plot(points, add = TRUE)


# Filter points within a tolerance distance (default: 0.01)
filtered_points <- remove_points_near_endpoints(points, linestring)

# Plot the filtered points
plot(linestring, col = "gray")
plot(filtered_points, add = TRUE)
