[GRASS-user] conversion to fire simulation data set in the Grass GIS

[Helmut Kudrnovsky]

>We also need to convert our one file to that type of dataset.

looking at the r.ros manual
(https://grass.osgeo.org/grass75/manuals/r.ros.html)

[...]
model=name [required]
    Raster map containing fuel models
    Name of an existing raster map layer in the user's current mapset search
path containing the standard fuel models defined by the USDA Forest Service.
Valid values are 1-13; other numbers are recognized as barriers by r.ros.
moisture_1h=name
    Raster map containing the 1-hour fuel moisture (%)
    Name of an existing raster map layer in the user's current mapset search
path containing the 1-hour (<.25") fuel moisture (percentage content
multiplied by 100).
moisture_10h=name
    Raster map containing the 10-hour fuel moisture (%)
    Name of an existing raster map layer in the user's current mapset search
path containing the 10-hour (.25-1") fuel moisture (percentage content
multiplied by 100).
moisture_100h=name
    Raster map containing the 100-hour fuel moisture (%)
    Name of an existing raster map layer in the user's current mapset search
path containing the 100-hour (1-3") fuel moisture (percentage content
multiplied by 100).
moisture_live=name [required]
    Raster map containing live fuel moisture (%)
    Name of an existing raster map layer in the user's current mapset search
path containing live (herbaceous) fuel moisture (percentage content
multiplied by 100).
velocity=name
    Raster map containing midflame wind velocities (ft/min)
    Name of an existing raster map layer in the user's current mapset search
path containing wind velocities at half of the average flame height
(feet/minute).
direction=name
    Name of raster map containing wind directions (degree)
    Name of an existing raster map layer in the user's current mapset search
path containing wind direction, clockwise from north (degree).

these are raster maps

looking at your excel file, it seems there are only a few points with some
additional information like  Latitude, Longitude, Slope, Elevation, Aspect.
these are vector points.

for a simulation in a computional region of your interest, you need these
input raster maps mentioned in the the r.ros, r.spread and  r.spreadpath
manuals.

it seems these input raster maps can't be produced by your point information
data; these input raster maps may be compiled by yourself based on some
suppporting data by yourself.
