pkascii2img

program to create raster image based on ascii file

SYNOPSIS

Usage: pkascii2img -i input.txt -o output

Options: [-ot type] [-of GDALformat] [-co NAME=VALUE]* [-dx value] [-dy value] [-ulx value] [-uly value] [-ct filename] [-a_srs EPSG:number] [-d description]

Description

The utility pkascii2img creates a raster dataset from an ASCII textfile. The textfile is in matrix format (rows and columns). The dimensions in x and y are defined by the number of columns and rows respectively. The georeferencing can be defined by providing the options for cell size (-dx -dy), upper left position (-ulx -uly) and the projection (-a_srs). Some dataset formats can also store a description (-d) and a color table (-ct).

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 image file
  ot	otype	std::string	Byte	Data type for output image ({Byte/Int16/UInt16/UInt32/Int32/Float32/Float64/CInt16/CInt32/CFloat32/CFloat64}). Empty string: inherit type from input image
  of	oformat	std::string	GTiff	image type string (see also gdal_translate)
  co	co	std::string		Creation option for output file. Multiple options can be specified.
  ulx	ulx	double	0	Upper left x value bounding box (in geocoordinates if georef is true)
  uly	uly	double	0	Upper left y value bounding box (in geocoordinates if georef is true)
  dx	dx	double		Output resolution in x (in meter)
  dy	dy	double		Output resolution in y (in meter)
  ct	ct	std::string		color table (file with 5 columns: id R G B ALFA (0: transparent, 255: solid)
  a_srs	a_srs	std::string		Override the projection for the output file
  d	description	std::string		Set image description

  Usage: pkascii2img -i input.txt -o output
