NAME

       pkinfo - Report basic information from raster datasets

SYNOPSIS

       pkinfo -i input [options]

DESCRIPTION

       pkinfo  retrieves  basic information about a raster data set (similar to gdalinfo(1)).  An
       important difference with gdalinfo is that pkinfo only reports  the  information  that  is
       requested  via  the corresponding command line option, whereas gdalinfo provides all basic
       information at once.  The reported information is in a format that can be  used  as  input
       for  other pktools utilities.  This mechanism facilitates command substitution in the bash
       scripting language.

EXAMPLE

       show number of bands in raster image.tif

       pkinfo -i image.tif -nb

       show maximum value of band 1 (starting from 0) of raster image.tif

       pkinfo -i image.tif -max -b 1

       read (dump) upper left pixel value for bands 3,2,1

       pkinfo -i image.tif -x 0 -y 0 -r -b 3 -b 2 -b 1

       read (dump) pixel value at this geographic location (x,y) for bands 3,2,1

       pkinfo -i image.tif -x 3528120 -y 4329681 -geo -r -b 3 -b 2 -b 1

       show bounding box (-ulx -uly -lrx -lry) in geo coordinates for image1.tif

       pkinfo -i image1.tif -b

       show bounding box (-ulx -uly -lrx -lry) in geo coordinates for each image (and  union  and
       intersect)

       pkinfo -i image1.tif -i image2.tif -i image3.tif -b

       show  the  reference  pixel  (centre  of gravity) for image1.tif, treating 0 and 255 as NO
       VALUE

       pkinfo -i image1.tif --mask 0 --mask 255 -ref

       read (dump) pixel value at image centre for band 0

       pkinfo -i image.tif $(pkinfo -i image.tif -c) -geo -r

       read (dump) pixel value in band 0 (default) for all images in current directory that cover
       this geographic location

       pkinfo $(for IMAGE in modis_2010*.tif; do pkinfo -i $IMAGE --cover -x 4215500 -y 2534000; done) -x 4215500 -y 253400
