NAME
pkfilterdem - Filter digital elevation model raster datasets
SYNOPSIS
pkfilterdem -i input -o output [ options ] [ advanced options ]
DESCRIPTION
pkfilterdem can be used to filter digital elevation models. It is typically used after the utility pklas2img (1) to create a digital terrain model. The default filter operation is the progressive morphological filter ⟨ http://ieeexplore.ieee.org/xpl/login.jsp?tp=&arnumber=1202973&url=http%3A%2F%2Fieeexplore.ieee.org%2Fxpls%2Fabs_all.jsp%3Farnumber%3D1202973⟩ .
OPTIONS
-i filename , --input filename
input image
-o filename , --output filename
output classification image
-f filter , --filter filter
post processing filter: vito, etew_min, promorph (progressive morphological filter), open, close).
-dim maxsize , --dim maxsize
maximum filter kernel size
-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 colortable , --ct colortable
color table (file with 5 columns: id R G B ALFA (0: transparent, 255: solid)). Use none to omit color table
-nodata value , --nodata value
nodata value
-v level , --verbose level
verbose mode if > 0
Advanced options
-circ
,
--circular
circular disc kernel for dilation and erosion
-st threshold , --st threshold
slope threshold used for morphological filtering. Use a low values to remove more height objects in flat terrains
-ht threshold , --ht threshold
initial height threshold for progressive morphological filtering. Use low values to remove more height objects. Optionally, a maximum height threshold can be set via a second argument (e.g., -ht 0.2 -ht 2.5 sets an initial threshold at 0.2 m and caps the threshold at 2.5 m).
-minchange number , --minchange number
Stop iterations when no more pixels are changed than this threshold.
