Interactive Tab

In the interactive tab you can perform transformation of single points and view information like scale and meridian convergence of the output system.
Spatial reference systems are specified as so called MiniLabel, see a description of the syntax here.
You can select predefined systems from the drop down lists.

NOTE: It is also possible to type MiniLabels yourself in the text fields for input and output systems. In this way all valid MiniLabels are available independently of the region you have chosen to work in, which only determines the predefined default systems. Hitting enter in the input or output system fields will trigger a new transformation.

Units

You can specify units at the end of coordinates, if you like, but this is not necessary. Generally units are in meters (m), except for geographic systems where the angular units for coordinates can be:
You can specify the units to use for geographic systems and derived angular output (meridian convergence, azimuth) in the 'Settings' menu item.



Triggering a transformation

To trigger a new transformation, hit enter in either an input coordinate field, input or output system fields or simply by changing input or output system from the drop down list.
A transformation can also be triggered by pressing the 'Transform' button below the output fields.
Changing the input system will not automatically alter the coordinates in the input fields (as in the 'old' KMSTrans) - instead this triggers a transformation of what is already in the input fields, as when the output system is changed. If you want to change the input system and also have the input coordinates transformed/updated, use the 'swap input/output' button.


Regions

Changing the region will have an effect on the predefined systems in the input and output system drop down lists, where systems relevant for the selected region are listed. You will still, however, be able to use any system you like by typing in the text fields. For example a Danish projection like dkmt1 can be selected by typing the mini label when using the 'World' region.

Message Box

Error messages and various extra information from the transformation will appear in the message box in the lower right corner of the window. For example if a transformation produces an error or warning it will be displayed in the message box.
