Polyline/polygon splitter tools for R. These functions will allow a user to pass SpatialLines or SpatialPolygons and split the line or polygon edge by a specific distance returning either points or line segments depending on which functions are used.

Usage can be see in the test.r file. These tools were designed for tasks were precise measurements along lines or polygon perimeters are required. This might include tasks like defining river miles along river lines, defining sample locations along excavation sidewalls, or changing the shapes of lines or polygons based on even distances along those shapes (a form of simplification).

Here are some examples:

This graphic shows how a polyline can be split into parts that are even length plus a remainder. The resulting line segments are shown in different colors.

This graphic shows how a polygon edge can be sampled at an even distance along its perimeter.

This graphic shows how a polygon can be simplified by taking even measurements along the perimeter, then converting those points back to a polygon. This example is not ideal. A better example might be a single contour output from a spatial interpolation or a trail path line from a GPS.
