TINSurfaceCreateR Documentation

FUSION R command line interface – Creates a DTM surface model using points in LIDAR data files (uses TIN then grids to final cell size).

Description

TINSurfaceCreate creates command lines for the FUSION TINSurfaceCreate program and optionally executes them.

Usage

TINSurfaceCreate(
  surfacefile = NULL,
  cellsize = NULL,
  xyunits = NULL,
  zunits = NULL,
  coordsys = NULL,
  zone = NULL,
  horizdatum = NULL,
  vertdatum = NULL,
  datafile = NULL,
  quiet = FALSE,
  verbose = FALSE,
  version = FALSE,
  newlog = FALSE,
  log = NULL,
  locale = FALSE,
  nolaszipdll = FALSE,
  skipfilecheck = FALSE,
  return = NULL,
  class = NULL,
  ignoreoverlap = FALSE,
  runCmd = TRUE,
  saveCmd = TRUE,
  cmdFile = NULL,
  cmdClear = FALSE,
  echoCmd = FALSE,
  comment = NULL
)

Arguments

surfacefile

character (required): Name for output surface file (stored in PLANS DTM format with .dtm extension). If the folder for the output file does not exist, it will be created when the function is called even when saving commands to a batch file.

cellsize

numeric (required): Desired grid cell size in the same units as LIDAR data.

xyunits

character (required): Units for LIDAR data XY (M for meters, F for feet, O for other or unknown).

zunits

character (required): Units for LIDAR data elevations (M for meters, F for feet, O for other or unknown).

coordsys

numeric (required): Coordinate system for LIDAR data: 0 for unknown 1 for UTM 2 for state plane)

zone

numeric (required): Coordinate system zone for LIDAR data (0 for unknown).

horizdatum

numeric (required): Horizontal datum: 0 for unknown 1 for NAD27 2 for NAD83

vertdatum

numeric (required): Vertical datum: 0 for unknown 1 for NGVD29 2 for NAVD88 3 for GRS80

datafile

character (required): Name(s) of lidar data files.

quiet

boolean: Suppress all output during the run.

verbose

boolean: Display all status information during the run.

version

boolean: Report version information and exit with no processing.

newlog

boolean: Erase the existing log file and start a new log

log

character: Use the name specified for the log file.

locale

boolean: Adjust program logic to input and output locale-specific numeric formats (e.g. use a comma for the decimal separator).

nolaszipdll

boolean: Suppress the use of the LASzip dll (c) Martin Isenburg... removes support for compressed LAS (LAZ) files. This option is only useful for programs that read or write point files.

skipfilecheck

boolean: Skip logic that checks for valid point files and removes those that are invalid prior to the start of point processing. This option is designed to overcome some limitations with windows and wildcard processing. This option is only useful for programs that read point data.

return

character: "ccc...": Specifies the returns to be included in the sample (can include A,1,2,3,4,5,6,7,8,9,F,L,O). Options are specified without commas (e.g. return="123"). For LAS files only: F indicates first and only returns, L indicates last of many returns.

class

character: "#,#,#,...": LAS files only: Specifies that only points with classification values listed are to be included in the subsample. Classification values should be separated by a comma. e.g. (2,3,4,5) and can range from 0 to 31. If the first character in string is ~, the list is interpreted as the classes you DO NOT want included in the subsample. e.g. /class:~2,3 would include all class values EXCEPT 2 and 3.

ignoreoverlap

boolean: Ignore points with the overlap flag set (LAS V1.4+ format).

runCmd

boolean: indicates command line should be executed.

saveCmd

boolean: indicates command line should be written to a file.

cmdFile

character: contains the name of the file to which commands should be written.

cmdClear

boolean: indicates file for commands should be deleted (cleared) before the command line is written.

echoCmd

boolean: indicates command line should be displayed.

comment

character string containing comment to be written to command file before writing the actual command. Only used when runCmd = FALSE and saveCmd = TRUE. When written, there is always a blank line before the comment line in the command file.

Value

Return value depends on runCmd. if runCmd = TRUE, return value is the (invisible) integer value return from the operating system after running the command. if runCmd = FALSE, return value is the (invisible) command line.

Multiple Commands

LTKFunctions generate a separate command for each item when the required parameters are lists. This is useful when you want to use the same command and options but different input data and output files. However, this works only when the switches and options are the same for all commands (not lists). If you try to use a list of switches and/or options and a list of input files, you will produce commands using all sets of switches and/or options for every input file.
