conv_shp_to_wkt: Convert SHP to WKT

In zoometh/iconr: Graphical and Spatial Analysis for Prehistoric Iconography

Convert SHP to WKT

Description

Convert the graphical units (GUs) geometries stored as shapefiles of POINTS, LINES, or POLYGONS into Well-Known Text (WKT) representations. Store the results in the 'nodes.csv' dataframe and return the path to this dataframe.

Usage

conv_shp_to_wkt(
  dataDir = system.file("extdata", package = "iconr"),
  complete.only = TRUE,
  out.dir = "_out"
)

Arguments

dataDir	Path of the folder storing folders of all decorations. Each of these folders as a site name (eg, Ain Ghazal) and contains at least one shapefile (.shp and .dbf and .shx) and one image (.jpg or .tif or .png, etc.). The shapefile is named conventionally with the name of the site, a dot,the name of the decoration, "nd_pl" for nodes POLYGONS (eg, Ain Ghazal.stat_2_nd_pl.shp). The image is named conventionally with the name of the site, a dot, and the name of the decoration (eg, Ain Ghazal.stat_2.tif).
complete.only	Boolean, if TRUE discard incomplete (incmplt == 1), by default = TRUE.
out.dir	Path of the output folder. By default "_out/" in the "dataDir" folder.

Value

Create the 'nodes.csv' file into the out folder, return the complete path of the 'nodes.csv' file.

Examples

dataDir <- system.file("extdata", package = "iconr")
nd.df.path <- conv_shp_to_wkt(dataDir = dataDir)
head(read.csv2(nd.df.path), 1)
