clgeo_Clean {cleangeo}

clgeo_Clean

Description

Function to clean a spatial data collection

Usage

clgeo_Clean(sp, errors.only = NULL, strategy = "SF", verbose = FALSE)

Arguments

sp

object extending the Spatial-class as defined in sp

errors.only

an object of class vector giving the types of errors for which the output should bounded. Default value is NULL (i.e. the output will include features for which both errors and errors were raised.).

strategy

advanced strategy to clean geometries. Default is "SF", alternate values are "POLYGONATION, "BUFFER" (old methods).

verbose

Indicates wether the clean logs have to be printed. Default value is FALSE.

Value

an object extending the Spatial-class as defined in sp, with cleaned geometries.

Note

About cleaning strategy: The polygonation method is a tentative alternate method to triangulation to clean geometries and to the classical often used 'buffer' approach. In the polygonation method, triangulation is skipped and a re-polygonation intuitive algorithm is applied to rebuild the source invalid geometry into one or more valid polygonal geometries. With the progress done on validating geometries, especially with sf, the default method in cleangeo has now been switched to the use of sf::st_make_valid

Examples

 require(sf)
 file <- system.file("extdata", "example.shp", package = "cleangeo")
 sf <- sf::st_read(file)
 sp <- as(sf, "Spatial")
 
 sp.clean <- clgeo_Clean(sp)
 report.clean <- clgeo_CollectionReport(sp.clean)
 clgeo_SummaryReport(report.clean)
