11.2 Creating a New Coordinate System/Editing a Coordinate SystemAccessstep-by-stepMANAGEXX CoordinateSystemStep Description1. Refer to "6 Manage... - Getting Started" to access MANAGE CoordinateSystems.2. In MANAGE Coordinate Systems highlight a coordinate system. Whencreating a new coordinate system, a copy of this coordinate system istaken for further configurations.3. NEW (F2)/EDIT (F3) to access MANAGE New CoordinateSystem/MANAGE Edit Coordinate System.Editing a coordinate system is similar to creating a new coordinate system. Forsimplicity, the screens are called MANAGE XX Coordinate System and differencesare clearly outlined.When editing a coordinate system the transformation type of the selected coordinatesystem determines the availability and the options of the subsequent fields. Mostfields are identical with those for the creation of a new coordinate system.Description of fieldsField Option Description User input A unique name for the coordinate system.The name may be up to 16 characterslong and may include spaces.Available for transformations with controlpoints. The method by which residuals aredistributed throughout the transformationarea.NoneNo distribution is made. Residuals remainwith their associated points.1/Distance XX Distributes the residuals according to thedistance between each control point andthe newly transformed point.Multiquadratic Distributes the residuals using a multiquadraticinterpolation approach. Choicelist The type of transformation. Output Available for editing Twostep transformations.The name of a preliminary 3D transformationwhich is used together with theselected projection to obtain preliminarygrid coordinates to be used for a final 2Dtransformation. Choicelist Available unless projection . The local coordinates arebased on this ellipsoid.66 TPS1200+ Manage...\Coordinate Systems
