Dear all,
We just tried a test with v.isochrones on Grass 7 (windows 32 bits).
We set the resolution 'ew' and 'ns' on 100.
Our road network comes from OSM data. We edited the network and kept only
usefull roads for car isochrony. We erected speed profile values. We chose
the r.cost method.
Below, i paste the error message. Could you throw light for me?
Thanks.

v.to.rast terminé.
Description:
Creates a raster map showing the cumulative cost of moving
between different geographic locations on an input raster
map whose cell category values represent cost.
Keywords:
raster, cost surface, cumulative costs, cost allocation
Usage:
r.cost [-knri] input=name output=name [nearest=name]
[outdir=name]
[start_points=name] [stop_points=name] [start_rast=name]
[start_coordinates=east,north[,east,north,...]]
[stop_coordinates=east,north[,east,north,...]]
[max_cost=value]
[null_cost=value] [percent_memory=value] [--overwrite]
[--help]
[--verbose] [--quiet] [--ui]
Flags:
-k Utiliser le "mouvement du cavalier (aux échecs)";
plus lent, mais plus précis
-n Keep null values in output raster map
-r Démarrer avec les valeurs de la couche raster
-i Print info about disk space and memory requirements
and exit
--o Autoriser la sortie à écraser les fichiers existants
--h Print usage summary
--v Sortie du module en mode bavard
--q Sortie du module en mode silence
--ui Force launching GUI dialog
Parameters:
input Name of input raster map containing
grid cell cost information
output Nom de la couche matricielle en sortie
nearest Name for output raster map with
nearest start point
outdir Name for output raster map to contain
movement directions
start_points Name of starting vector points map
Or data source for direct OGR access
stop_points Name of stopping vector points map
Or data source for direct OGR access
start_rast Name of starting raster points map
start_coordinates Coordinates of starting point(s) (E,N)
stop_coordinates Coordinates of stopping point(s) (E,N)
max_cost Maximum cumulative cost
par défaut: 0
null_cost Coût assigné aux cellules vides. Par
défaut, les cellules vides sont ignorées
percent_memory Pourcentage de la couche à garder en
mémoire
options: 0-100
par défaut: 40
