PROGRAM:
NAME
pkstatprofile - program to calculate statistics in temporal or spectral profile
SYNOPSIS
pkstatprofile -i input -o output [-f function] [options]
DESCRIPTION
pkstatprofile calculates statistics for a temporal (time series) or spectral profile.
Function Description
mean calculate mean in window
median perform a median filter in
spatial (dx, dy) or
spectral/temporal (dz) domain
var calculate variance in window
stdev calculate standard deviation in
window
min calculate minimum in window
max calculate maximum in window
sum calculate sum in window
mode calculate mode of all values
ismin 1 if value is minimum, else 0
ismax 1 if value is maximum, else 0
per calculate percentile in time
series (provide percentage value
as argument)
prop calculate proportion
nvalid report number of valid
observations
Calculate min and max NDVI in time series
pkstatprofile -i modis_ndvi_2010.tif -o modis_stats_2010.tif -f min -f max
OPTIONS
-i filename, --input filename
Input image file.
-o filename, --output filename
Output image file
-f function, --function function
Statistics function (mean, median, var, stdev, min, max, sum, mode (provide
classes), ismin, ismax, proportion (provide classes), percentile, nvalid
-perc percentile, --perc percentile
Percentile value(s) used for rule percentile
-class class, --class class
class value(s) to use for mode, proportion
-nodata value, --nodata value
Set nodata value(s)
-ot type, --otype type
Data type for output image ({Byte / Int16 / UInt16 / UInt32 / Int32 / Float32 /
Float64 / CInt16 / CInt32 / CFloat32 / CFloat64}). Empty string: inherit type from
input image.
-of format, --oformat format
Output image format (see also gdal_translate(1)).
-ct filename, --ct filename
Color table (file with 5 columns: id R G B ALFA (0: transparent, 255: solid). Use
none to ommit color table.
-co NAME=VALUE, --co NAME=VALUE
Creation option for output file. Multiple options can be specified.
-d value, --down value
Down sampling factor. Use value 1 for no downsampling. Use value n>1 for
downsampling (aggregation).
-v level, --verbose level
Verbose mode if > 0
