FUSIONtools: FUSION tools

In AndyPL22/rFUSION: Tools for calling FUSION commands in R

Description

Functions for calling FUSION tools. Consult the FUSION manual for more details on these tools, their inputs and their outputs. FUSION must be installed and the rFUSION.path global option must direct to the FUSION folder in which all tool executable files are stored. The FUSIONfolder function can be used to define this path.

Arguments

xyunits	character. "m" for meters, "f" for feet.
zunits	character. "m" for meters, "f" for feet.
coordsys	numeric. Geographic coordinat system. 0 for unknown, 1 for UTM, 2 for state plane.
zone	numeric. Coordinate system zone. 0 for unknown.
horizdatum	numeric. Horizontal datum. 0 for unknown, 1 for NAD27, 2 for NAD83
vertdatum	numeric. Vertical datum. 0 for unknown, 1 for 1 for NGVD29, 2 for NAVD88,3 for GRS80.
cellsize	numeric. Cell size of an output raster file.
class	numeric. Used to restrict a function to certain classified points.
ground	A PLANS format DTM file representing a digital elevation model (DEM). Generally used to normalize a point cloud to height above ground.
gridxy	numeric. Vector of four numbers: X1, Y1, X2, Y2. Force the origin of an output raster (lower left corner) to be (X1,Y1) instead of computing an origin from the data extents and force the upper right corner to be (X2, Y2). WARNING: the rFUSION.grixyAdjust global option can influence the behaviour of this argument. See GridXY for more details.
align	A PLANS format DTM file to which an output raster will be aligned. Same behavior as gridxy, except parameters are read from the DTM file.
extent	A PLANS format DTM file. Force the origin and extent of the output grid to match the lower left corner and extent of the specified DTM file but adjust the origin to be an even multiple of the cell size and the width and height to be multiples of the cell size.
