pkascii2ogr - program to create vector points or polygons from text file


pkascii2ogr
[-i input] [-o output] [-f OGRformat] [-x col] [-y col] [-line] [-n fieldname] [-ot type] [-fs separator]

pkascii2ogr creates a vector dataset (points or single polygon) from an ASCII textfile. A better alternative is to use virtual vector datasets ⟨http://www.gdal.org/drv_vrt.html⟩ . 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.

input ASCII file
Output file
Output sample file format
column number of x (0)
column number of y (1)
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)
Field names for the columns in the input ascii file
Field type (Real, Integer, String) for each of the fields as defined by name
Override the projection for the output file, use epsg: or Wkt string
field separator.

Create a vector shape file (output.shp) from input ASCII file (input.txt). The coordinates x (longitude) and y (latitude) can be found in input.txt as columns 3 and 2 respectively (columns start counting from 0). The remaining 2 columns in input.txt are used as fields (attributes) of type integer: id (column 0) and label (column 3). The projection is set to lat lon (epsg:4326).

pkascii2ogr -i input.txt -o output.shp -x 2 -x 1 -n id -ot Integer -n label -ot Integer -a_srs epsg:4326
