QuickGrid is designed to allow for quick coordinate system determination on
site. Particularly for those users who must combine GS and TS data. All points
must be measured by GS. QuickGrid is not available in TS mode. There are sev-
eral methods to choose from.
Select QuickGrid from the Leica Captivate - Home menu.

Description
This method is fast and targeted at the basic
customer who wants to set up a local coordi-
nate system based on a single point.
The orientation is fixed to WGS 1984 north.
A height scale is applied to bring GS distan-
ces to "ground" using measured point
WGS 1984 height.
This method is fast and targeted at the more
rigorous customer who wants to set up a
local coordinate system based on multiple
points.
Rotation and scale are as calculated.
This method is fast and targeted at the basic
customer who wants to set up a local coordi-
nate system based on the base station posi-
tion.
The orientation is fixed to WGS 1984 north.
A height scale is applied to bring GS distan-
ces to "ground" using measured point
WGS 1984 height.
This method is fast and targeted at the more
advanced customer who wants to set up a
local coordinate system based on a single
point, but set the orientation of the resulting
grid by measuring a second point.
The rotation is as calculated.
A height scale is applied to bring GS distan-
ces to "ground" using measured point
WGS 1984 height.
This method is fast and targeted at the more
advanced customer who wants to shift their
existing coordinate system based on a single
point.
A 3D transformation is calculated.
