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. ----------------------------------------------------- (Thu Dec 17 10:55:58 2015) v.isochrones map=Road_IDF_iso_VOITURE_L93@Dataset_AD_iso roads_layer=1 cost_column=MS_profil start_points=Loc_GE_PS@Dataset_AD_iso isochrones=ISO_Voit_GE_PS_15_min time_steps=15 timemap=raster_iso_voit_15 method=r.cost Unknown module parameter "keyword" at line 18 Unknown module parameter "keyword" at line 19 Unknown module parameter "keyword" at line 20 Pass 1 of 15: Reading features...
