NAME
ISMcont2dig - Converts a binary ISM contour data file to a binary
GRASS vector (dig) file.
(GRASS Vector Data Import Program)
SYNOPSIS
ISMcont2dig
ISMcont2dig help
ISMcont2dig input=name output=name
DESCRIPTION
This program converts a binary ISM contour data file into a binary
GRASS vector (dig) file.
ISMcont2dig also creates a dig_att file containing the label
information from the ISM contour file.
However, the user must run v.support (or v.import option 4)
on the output file created by ISMcont2dig to create a
dig_plus file containing the file topology, before using the
output file in v.digit.
COMMAND LINE OPTIONS
Parameters:
- input=name
- Name of binary ISM contour data input file.
- output=name
- Name to be assigned to the binary GRASS vector files created.
If the user simply types ISMcont2dig without specifying parameter
values on the command line, the program will prompt the user to enter these.
NOTES
To create a contour file from ISM for use by ISMcont2dig, turn on option
7 (contour output file) under CONTOUR/BASE MAP OPTIONS. To achieve better
contour resolution, also change options 12 and 13 (minimum separation) under
this same menu to some minimum number such as .00001. The ISM user may wish to
save these options as an ISM options file. Plot the map as usual. At run
time, ISM will prompt the user for a filename and ask whether the contour
output format should be binary (default) or ASCII. Only BINARY contour files
may be used by ISMcont2dig.
