dshm_split_transects: Splitting transect lines into segments

In FilippoFranchini/dshm: Density surface modelling unsing Hurdle approach for zero inflation

Description

Splits transect lines into segments, adds buffer, and attaches data.

Usage

dshm_split_transects(transect.data, inter.dist = 0.01, lwr,
  search.time = 15, w, parallel = FALSE, ncores = NULL, cap = TRUE)

Arguments

transect.data	Transect lines as SpatialLinesDataFrame.
inter.dist	Distance between each segment in meters. Default is 10 cm.
lwr	Lower limit in meters for segments.
search.time	Time in seconds the routine has to search for the solution. Default is 15s. Note this is not the time required to finish calculations. See the split_transects.pdf tutorial for more information.
w	Segment buffer in meters.
parallel	If TRUE calculations are carried out on multiple cores. Default is FALSE.
ncores	Number of cores.
cap	If TRUE a cap is added to the ends of each splitted transect.

Details

For more information about splitting transects into segments as well as checking and correcting segments you can download the split_transects.pdf tutorial.

Value

Segments as SpatialPolygonsDataFrame with attached data:

• Transect.Label: ID for split transect.

• Sample.Label: ID for segment.

• lenght: segment length.

• area: segment area.
