NAME
v.circle - Creates a vector file which consists of circle(s) which uses each point in a "site_lists" file as the center of those circle(s).
(GRASS Vector Program)
SYNOPSIS
v.circle
v.circle help
v.circle [ -s] sitefile=name
[radius=value] [radius_uom=name]
[area=value] [area_uom=name]
output=name
DESCRIPTION
"v.circle" will create "polygon" circle(s) around points read from an existing
"site_lists" file. The "site_lists" point(s) will be the center(s) for those
circle(s) with one circle created per point. The "polygon" circle(s) will be
written to a binary vector file. Each "polygon" circle will have 361 points
with each point on the circumference of the circle representing 1 degree of
arc.
COMMAND LINE OPTIONS
Flags
-s
Automatically run "v.support" on newly created vector file.
Parameters
radius
Radius of circle(s) with "site_lists" point(s) as center(s). If radius selected then area values are not used for computations. If both radius and area selected, then radius has precedence over area.
default: 0.0
radius_uom
Radius unit of measure, ie. (m)meters, ft(feet), (mi)miles.
default: m
area
Area of circle(s) with "site_lists" point(s) as center(s). If area selected then radius values are not used for computations.
default: 0.0
area_uom
Area unit of measure, ie. sqm(square meters), ac(acres), sqmi(square miles), hec(hectares).
default: sqm
sitefile
GRASS site_lists file (input).
output
Vector file to be created (output).
