pkstatprofile(1)

💖 pkstatprofile — the manual, but make it make sense 💖

okay so bestie, welcome to pkstatprofile, a lil program from the pkstatprofile(1) manual that calculates statistics for you. no cap, it's giving "I do math on your rasters while you sip your iced coffee" energy. ✨

---

🌸 SYNOPSIS 🌸

pkstatprofile -i input -o output [-f function] [options]

that's the whole vibe. -i in, -o out, and then you sprinkle your stats on top like glitter. 🦋

---

✨ DESCRIPTION ✨

pkstatprofile calculates statistics for a temporal (time series) or spectral profile. literally what it says on the tin. 💅

here's the whole menu of function values, fr fr:

• 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

heads up bestie: a couple of these need extra info from you — mode wants classes, proportion wants classes, and percentile wants a percentage value. iykyk. 🎀

🌈 example: min and max NDVI in a time series

pkstatprofile -i modis_ndvi_2010.tif -o modis_stats_2010.tif -f min -f max

see? two -f flags, two stats, one iconic output file. periodt. 👑

💅 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 omit 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

gentle reminder: -ct has an unclosed paren situation in the original and we're keeping it exactly as-is, because the facts don't change, only the vibes do. 🙈

🫶 the cute lil sign-off 🫶

and that's the whole page, bestie!! this was the pkstatprofile(1) manual, dated 01 January 2025, and the footer says the same thing twice because that's just how manpages are. slay. 💖✨🎀🦋
