aspace (version 0.1)

makeshapes: Builder of ESRI Shapefiles

Description

This function is a basic ESRI Shapefile builder. The SDD, SDE, and MCP functions included in this library produce ASCII output files that represent the input required for this function. However, any similarly formatted file will also work. This function provides capabilities for converting the centrographic and geometric summary measures of geographical extent and dispersion into GIS databases for further cartographic rendering and analysis.

Usage

makeshapes(asciiname = "SDD_Output.txt", headerskip = 0, outname = "Test", verbose = TRUE)

Arguments

asciiname

The name of the ASCII file containing coordinate info. input to the shape building procedure

headerskip

An integer to indicate how many lines of the ASCII file to skip at the top if a header has been added

outname

The name of the output Shapefile. Do not use spaces or illegal filename characters.

verbose

Boolean: Set to TRUE if extended feedback to the standard output is required

Value

• The result is an ESRI format Shapefile containing 3 files (.shp, .dbf, .shx). The base filename will be that specified by the parameter outname.

Details

The level of detail recorded in the Shapefile will be determined by the weed tolerance of points defining the shapes in the input ASCII file.
