Cut segment into sub-segment with a specific length

Source: R/TNETshape_cutSegments.R
TNETshape_cutSegments.Rd

This function will cut segment into sub-segments with a length betweem length_min and 2*length_min meter. Each segments and nodes created will have a unique ID.

Usage

TNETshape_cutSegments(path_segments,path_node,export_segments,export_node, length_min)

Arguments

path_segments

Path to the shapefile with segments to merge.

path_node

Path to the shapefile with all segments nodes.

export_segments

filename for the exported shapefile with segments created.

export_node

filename for the exported shapefile with nodes created.

length_min

minimum length of segments (m). Final segment length will be between length_min and 2*length_min.

Value

list of both created segment and node shapefiles.

Details

This function will cut all segments exceding \(2\times\text{length_min}\) meter into smaller segments with unique IDs. The ID of the most downstream created segments is kept identical to the Id of the original segment.

Here a figure resuming the computation done in this function:

The computation of cutting the segments is made by sf::st_line_sample(), where we removed the first and last node to have not to small segments.

Examples

## Run directly the function providing all info
TNETshape_cutSegments(path_segments = "path/to/segments.shp",
                      path_node = "path/to/nodes.shp",
                      path_export = "path/to/exportFolder")
#> Error in TNETshape_cutSegments(path_segments = "path/to/segments.shp",     path_node = "path/to/nodes.shp", path_export = "path/to/exportFolder"): unused argument (path_export = "path/to/exportFolder")
