Localization Reset Origin
The Localization Set Zone screen is used to manually key in the
parameters for the default map projection zone used in the
localization adjustment. You can also open the Select Coordinate
System screen where you can choose a record from the coordinate
system database file.
1. Go to Survey > Projection > Set Zone to
open the Localization Set Zone screen.
2. Enter the Setup Group for the zone. The
setup group is used to associate this zone
with the autonomous base setup. The setup
group should usually be the same as the
current RTK base.
3. Enter the Origin Latitude and Origin
Longitude
for the zone. The origin
coordinate is usually at the same location
as the RTK base.
4. Enter the Origin Height for the zone. The origin height is used to
calculate the zone’s scale factor to configure this zone for ground
distances. Alternatively, you can toggle this control and enter the
Origin Scale
directly.
5. Check the Use Geoid checkbox if you want to use a geoid model
with this zone and then select a geoid model from the dropdown
list to use with the coordinate system. When this box is
unchecked, no geoid will be used with the coordinate system.
Note: If you have an RTK base configured in Survey Pro, and if you
wish to set up this localization zone to match the setup group and
location of that base, tap Same As Base to fill in all the parameters on
this screen.
