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.
OPTIONS
-i filename, --input filename Input image file -bb, --bbox Shows bounding box -te, --te Shows bounding box in GDAL format: xmin ymin xmax ymax -c, --center Image center in projected X,Y coordinates -ct, --colortable Shows colour table -ns, --nsample Number of samples in image -nl, --nline Number of lines in image -nb, --nband Show number of bands in image -b band, --band band Band specific information -dx, --dx Gets resolution in x (in m) -dy, --dy Gets resolution in y (in m) -mm, --minmax Shows min and max value of the image -min, --minimum Shows min value of the image -max, --maximum Shows max value of the image -stats, --statistics Shows statistics (min,max, mean and stdDev of the image) -a_srs, --a_srs Shows projection of the image -geo, --geo Gets geotransform -il, --interleave -f, --filename Shows image filename -cover, --cover Print filename to STDOUT if current image covers the provided coordinates via bounding box, (x y) coordinates or extent of vector file -x value, --xpos value x pos -y value, --ypos value y pos -r, --read Reads row y (in projected coordinates if geo option is set, otherwise in image coordinates, 0 based) -ref, --reference Gets reference pixel (lower left corner of center of gravity pixel) -of, --oformat Gets driver description -e filename, --extent filename Gets boundary from vector file -ulx ULX, --ulx ULX Upper left x value bounding box -uly ULY, --uly ULY Upper left y value bounding box -lrx LRX, --lrx LRX Lower right x value bounding box -lry LRY, --lry LRY Lower right y value bounding box -ot, --otype -d, --description Returns image description -meta, --meta Shows meta data -nodata value, --nodata value Sets no data value(s) for calculations (nodata values in input image)
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
