pkascii2ogr

program to create vector points or polygons from text file

SYNOPSIS

Usage: pkascii2ogr -i input.txt -o output

Options: [-f OGRformat] [-x col] [-y col] [–line] [-n fieldname -ot type]* [-fs separator]

Description

Poor man's utility to create a vector dataset (points or single polygon) from an ASCII textfile. A better alternative is to use virtual vector datasets. Specify the position of the vertices (x and y) in the columns defined by the options (-x -y), starting from 0. The default is to use the first (-dx 0) and second (-dx 1) columns for x and y respectvely. Specify the names and types of the remaining columns in your input file via the option pairs -n and -ot respectively. The default field separator is space.

Options

• use either -short or --long options (both --long=value and --long value are supported)
• short option -h shows basic options only, long option --help shows all options

  short	long	type	default	description
  i	input	std::string		Input ASCII file
  o	output	std::string		Output file
  f	f	std::string	ESRI Shapefile	Output sample file format
  x	x	short	0	column number of x (0)
  y	y	short	1	column number of y (1)
  l	line	bool	false	create OGRPolygon as geometry instead of points. Fields are taken from first point and polygon is automatically closed (no need to repeat first point at last line). (false: use OGRPoint)
  n	name	std::string		Field names for the columns in the input ascii file
  ot	ot	std::string	Real	Field type (Real, Integer, String) for each of the fields as defined by name
  a_srs	a_srs	std::string	epsg:4326	Override the projection for the output file, use epsg: or Wkt string
  fs	fs	char		field separator.

  Usage: pkascii2ogr -i input.txt -o output
