The Projection Settings card is used to define the projection mode you
will use to calculate horizontal and vertical coordinates in your
survey.

Horizontal

: contains the following options for your

horizontal projection.

Ground - TDS Localization

: use this setting to

transform GPS coordinates into a ground level
local system using a default TDS map projection
set up to produce ground distances at the GPS
base point origin.

Mapping Plane

: use this setting to transform

GPS coordinates to a selected mapping plane

Vertical

: contains the following options for your vertical

projection.

Localization (+Geoid)

: use this setting to have a

geoid model with or without a localization
vertical adjustment.

Ellipsoid Height

: use this setting when no transformation of

measured ellipsoid heights is desired. Point elevations will be
local ellipsoid heights.

Database

: is where you select the coordinate system database to use.
