Objects, Point Roles and Symbols

Infinity is an object-oriented software. The objects are the basic entities for performing operations. All objects are intelligent objects which means that they are interrelated with each other.

Icon	Object	Description
	Points	A point is a named object that represents a location with either local or global latitude and longitude coordinates, and possibly a height or elevation.
	Lines	A line is used to describe feature objects by drawing a line between two or more points.
	Areas	An area is a closed line object.
	Setups	A setup is the source of any measurement observation.
	Observations	An observation is the measurement that defines the source of a point.
	GNSS Tracks	A GNSS track is an object resulting from processing moving or mixed data.
	Traverses	A traverse is a series of intervisible points at which angles are measured and also distances can be measured, to determine the station setups.
	Sets of Angles	A set of angles are a series of observations that are reduced to an angular value. The angular value is then coordinated from the source of the observations.
	Surfaces	A surface is a triangulation network representing points, cloud points, lines and areas.
	Point Cloud Groups	A point cloud group is a defined group of point clouds that represents a single object, used for cleaning or surface creation.
	Point Clouds	A point cloud is a measurement object from the data source.
	Image Groups	An image group is a defined group of images that you can measure image points from.
	Images	An image is a picture captured that is represented by its position or object it is assigned to.
	Georeferenced Images	An image that has been ortho-rectified and can be placed in the project coordinate reference frame.
	Alignments	The alignment is a linear object made of multiple segments geometrically defined and joined together.It defines the route of a road construction, generally its centreline or axis.
	Roads	A road is made of several objects including a centreline and a material layer. The material layer describes the stringlines assigned to it.
	Material Layers	Are the layers constituting a road. A material layer groups a set of stringlines that belong to the same level, material or phase of construction.
	Cross Sections	A cross section is a slice or cut at a certain chainage of the road, displaying the position of different linear features connected together in a cross section view.
	Cross Section Assignments	Result from cross sections templates being assigned to a road. Stringlines result from interconnecting cross section assignments.
	Stringlines	Are special line objects that can either be imported from CAD or defined through cross section assignment.
	Scan Setup	A setup belonging to a BLK360, RTC360 or RTC360LT.
	Scan Group	A group of scan setups that have been joined together by links.
	Registration Link	A line shown between two scan setups to symbolise that they have been joined by visual alignment or target matching.
	Used Registration Target	A target that has been used to join setups by target matching.
	Unused Registration Target	A target that has not been used to join setups by target matching.

Interval Icons for GNSS Tracks:

Icon	Object	Description
	Static Interval	This icon indicates that GNSS raw data is acquired with static mode.
	Moving Interval	This icon indicates that GNSS raw data is acquired with kinematic mode.
	Mixed Interval	This icon indicates that GNSS raw data is acquired with alternating static and kinematic modes.

Point Roles and Point Symbols:

Point Roles and Point Symbols:

Icon	Point Role	Description
	Control Point (not fixed in adjustment)	Is a control point that is not considered for adjustment and not fixed.
	1D Control Point (fixed in height)	Is a 1D control point that is considered for adjustment, fixed only in height.
	2D Control Point (fixed in position)	Is a 2D control point that is considered for adjustment, fixed only in position.
	3D Control Point (fixed in position and height)	Is a 3D control point that is considered for adjustment and fixed in position and height.
	Adjusted Measured Point	Is a measured point adjusted by the least squares method or in a traverse computation.The adjusted least squares point role, include the adjustment method 3D, 2D or 1D.
	Station Setup	Is a point on which a station setup exists after import of field data.
	Averaged Point	This point is derived by averaging two or more measured points.
	TPS Reduced Measurement	This point is generated from the reduced observation computed from sets of angles, reduced foresights or a traverse.
	TPS Measured with Reflector	Is a point that has been measured using a reflector.
	TPS Measured Reflectorless	Is a reflectorless measured point.
	TPS Measured with Reflector (compensated)	Is a tilt compensated point that has been measured using a reflector and the Leica AP20 sensor.
	TPS Measured	Is a point that has been measured without instrument EDM information.Typically, such points are imported from XML.
	TPS Measured Setup Point (with reflector)	Is a control point used in a Setup application and a measurement has been taken with reflector EDM.
	TPS Measured Setup Point (reflectorless)	Is a control point used in a Setup application and a measurement has been taken with reflectorless EDM.
	Fixed Real-Time Kinematic (RTK)/Fixed PP	Is a GNSS RTK measured or post-processed phase fixed point (most accurate).
	xRTK/Widelane PP	Is GNSS xRTK measured or a widelane post-processed phase fixed point.
	PPP Converged	Is a GNSS point measured with precise point positioning, final position converged.
	Float RTK/Float PP	Is a GNSS RTK measured or post-processed point with float solution (less accurate).
	PPP Converging	Is a GNSS point being measured with precise point positioning, final position not yet converged.
	Code RTK/Code PP	Is a GNSS RTK measured or post-processed point with code solution (least accurate).
	Navigated RTK/Navigated PP	Is a GNSS RTK measured or post-processed point with lower accuracy. It is measured without using a reference station.
	When the GNSS point roles have got a green background, this indicates a tilted measurement.
	GNSS Measured	Is a measured GNSS point with unknown solution type.Typically, such points are imported from XML or SKI ASCII.
	GNSS Track Post-Processed	Is a post-processed GNSS track (using a reference station).
	GNSS Track Navigated	Is a post-processed GNSS track computed by applying the SPP technique (without using a reference station).
	GNSS Track Averaged	Is a GNSS track derived by averaging two or more post-processed tracks.
	Level Measured	Is a point measured by level staff.
	Offset Point	Is a point for which an offset observation has been measured or entered.
	Auto Point	Is a point measured with the auto points application.
	Computed Point	Is a point calculated by an application and not measured with an instrument.
	User-entered Point	Is a manually entered point.
	Point (unknown)	Is a point for which no point role can be defined on import.Typically, such points are imported from XML.
	Point (deleted)	Is a point which has been deleted on the instrument and could be recovered.

When the GNSS point roles have got a green background, this indicates a tilted measurement.
