[GRASS-user] How to convert points distribution toward surface information?

[image93]

Good afternoon,


I have a points cover representing different bus and train stops. I applied
a categorized symbology : Each colour represents a class of value (field
regarding time acess from a starting point)

Iwould like represents this time information thanks to different polygons,
(Because in a 2nd time i have to intersects this information with another
POINTS cover )

Could you throw light for me? Rasterize this data would be a interesting
way? I tried with qgis vector -> convex envelope . But The result is not
what I am looking for ... the spatial distribution of points seems to be to
complex to convert the points cover toward convex envelope.

I paste below a SS of my current POINT data
