#3361: v.select: very slow using GEOS operators
--------------------------+---------------------------------------
Reporter: mlennert | Owner: grass-dev@…
Type: enhancement | Status: new
Priority: normal | Milestone: 7.4.1
Component: Vector | Version: svn-trunk
Resolution: | Keywords: v.select GEOS within slow
CPU: Unspecified | Platform: Unspecified
--------------------------+---------------------------------------
Comment (by mlennert):
Actually, it is not only within. Comparing the native 'overlap' operator
with its GEOS equivalent, the 'intersects' operator, I get significant
time difference:
{{{
time v.select -c ain=boundary_municp bin=rail5000 op=overlap
out=select_overlap
real 0m27.363s
user 0m12.836s
sys 0m14.696s
}}}
{{{
time v.select -c ain=boundary_municp bin=rail5000 op=intersects
out=select_intersects
real 1m12.190s
user 0m56.844s
sys 0m15.511s
}}}
