NAME
r.in.miads - Converts a MIADS output ASCII text file
into an GRASS raster import (r.in.ascii) formatted file.
(SCS GRASS Raster Program)
SYNOPSIS
r.in.miads
r.in.miads help
r.in.miads input=name output=name strip=value line=value cell=value
Northing=value Easting=value size=value
DESCRIPTION
r.in.miads allows a user to create a r.in.ascii formatted
ASCII file from a MIADS output printer format ASCII file.
The program will actively read the MIADS data file, selectively remove
and process each strip, creating a individual r.in.ascii formatted file
for each strip, and finally create one category file for all strips.
The program also produces a report file summarizing all pertinent
information for each strip.
The resulting r.in.ascii files for each strip are then used in
conjunction with the GRASS commands r.in.ascii and r.patch to
create a complete raster file.
COMMAND LINE OPTIONS
Parameters:
- input=name
- MIADS input file name.
- output=name
- GRASS raster data output file name.
- strip=value
- MIADSs strip number of reference cell.
- line=value
- MIADSs line number of reference cell.
- cell=value
- MIADS cell number of reference cell.
- Northing=value
- UTM Easting at the cell reference.
- Easting=value
- UTM Northing at the cell reference.
- size=value
- Cell size (length one side) in meters.
SCS has developed scripts run.miads, getstrip,
and strip.99s. These scripts make the MIADS to GRASS
conversion easier.
run.miads -
SCS macro to perform the complete conversion of a MIADS printer format data
set to a GRASS raster file.
getstrip -
Reads each MIADS strip file and converts it to a independent GRASS data
file. Support may be run on any one of these strip files; however,
there is no category information available. Each strip may be viewed at
this time with d.rast or d.display.
strip.99s -
Special pre-r.in.miads macro that removes the 99's from the MIADS data
file. This effectively removes border information, replacing it with
"no data" values.
