[GRASS-dev] PyGRASS vector operations

[Adrien ANDRÉ]

Dear list,

having a point, a radius and contour lines, i'd like to build a vector
map of segments, from the point to intersections of countour lines with
the point buffer of the given radius (the attached image might be clearer).

Traditionnaly, i'd use v.buffer, v.overlay op=and, v.to.points use=node
and then build the segments.


Is it possible to achieve this with PyGRASS without creating, opening
and closing temp maps for each step (i.e. pygrass.modules.Module call)?

Or do i have to use the GDAL Python API?
http://pcjericks.github.io/py-gdalogr-cookbook/geometry.html#calculate-intersection-between-two-geometries
for example.


Thank you in advance for any help.

Regards,

Adrien
