outtable - computes table of statistics from several epp files.
outtable [options] [function] file [ [function] file ...]
outtable takes several epp-files counts all possible combinations of
classes in them and produces table of them.
Some files can be preceded
by function Such files wouldn't be used to define new combination. Instead,
corresponding column of table would contain value of function, computed
from this file for area, defined by combination of classes of all "function-less"
files.
All files, used to define combination, should be specified before
first file with function.
If no function defined, table would be appended
by column, containing area of each combination.
If all files have function,
table would contain only one row, containing values of the functions for
all area.
If files have different cell size and limits, limits and coordinate
systems of the first file are used, unless overriden by --base option.
By default, semantic value of classes are considered equial to values
of classes. This can be overridden by specifying parameters of linear mapping
function using
-z and -Z options. This option can be specified only once
per invocation, becouse usially outtable is used to calculate statistics
for one file in combinations, given by several other files.
By default,
all area-related values are calculated in alternative coordinate units.
It can be overriden using -c option.
- --help
- displays brief usage
information.
- --version
- displays version number
- --verbose -%
- Displays percentage
of processed lines in file.
- -u --union
- Take into account all cells, where
at least one of output files is not offsite. By default, only cells where
all input files are onsite are taken into account.
- -c --cells
- Output areas
in cells. By default map units as specified in file header are used to
compute areas.
- -dchar --delimiter=char
- sets table column separator to char.
Defaults to comma.
- -b file--base file
- Specifies epp file, used as reference
grid. Cell area and cell size of this file, as well as its coordinate limits
would be used for processing. Defaults to first file in the command line.
- -z value
- Specifies multiplier for calculating semantic value from class
value.
- -Z value
- Specifies offset of semantic values, i.e. semantic value
of class 0.
- -sum
- Sum of classes in given file for combination,
multiplied by cell area.
- -cnt
- Count of onsite cells of given file.
- -avg
- Average cell value
- -min
- Minimum cell value
- -nmin
- Area of cells with minimum
value
- -max
- Maximum cell value
- -nmax
- Area of cells with maximum value
- -mode
- Modal value (value of most cells)
- -nmode
- Area of cells with modal
value
- -fewest
- Class with fewest cells
- -nfewest
- Area of cells in fewest
class
- -range
- Range of classes (maximum-minimum)
- -classes
- Number of different
classes
- -or
- Bitwise or of all cells (values of -z and -Z options are not
used)
- -and
- Bitwise and of all cells (values of -z and -Z options are not
used)
- -std
- Standard deviation of classes
- -var
- Variance of classes
- -corr
- Correlation coefficient between two files. Requires two arguments.
