wbt_dem_void_filling

This tool can be used to fill the void areas of a DEM using another fill DEM data set.

GeomorphometricAnalysis

An R frontend for the 'WhiteboxTools' library, which is an advanced geospatial data analysis platform developed by Prof. John Lindsay at the University of Guelph's Geomorphometry and Hydrogeomatics Research Group. 'WhiteboxTools' can be used to perform common geographical information systems (GIS) analysis operations, such as cost-distance analysis, distance buffering, and raster reclassification. Remote sensing and image processing tasks include image enhancement (e.g. panchromatic sharpening, contrast adjustments), image mosaicing, numerous filtering operations, simple classification (k-means), and common image transformations. 'WhiteboxTools' also contains advanced tooling for spatial hydrological analysis (e.g. flow-accumulation, watershed delineation, stream network analysis, sink removal), terrain analysis (e.g. common terrain indices such as slope, curvatures, wetness index, hillshading; hypsometric analysis; multi-scale topographic position analysis), and LiDAR data processing.

wbt_dem_void_filling function

<dl><dt>dem</dt>
<dd>Name of the input raster DEM file, containing the void areas.</dd>
<dt>fill</dt>
<dd>Name of the input fill DEM file, containing the values used to fill the void areas in the other DEM.</dd>
<dt>output</dt>
<dd>Name of the output void-filled DEM file.</dd>
<dt>mean_plane_dist</dt>
<dd>Distance to void edge at which the mean-plane value is used as an offset, measured in grid cells.</dd>
<dt>edge_treatment</dt>
<dd>How should void-edge cells be treated? Options include 'use DEM' (default), 'use Fill', 'average'.</dd>
<dt>weight_value</dt>
<dd>Weight value used for IDW interpolation (default is 2.0).</dd>
<dt>wd</dt>
<dd>Changes the working directory.</dd>
<dt>verbose_mode</dt>
<dd>Sets verbose mode. If verbose mode is <code>FALSE</code>, tools will not print output messages.</dd>
