Open/Show Object As Table

Select a table, a two-dimensional table, a histogram, a point map, an annotation text object, a domain class/ID, a representation class/picture, a georeference tiepoints or a coordinate system tiepoints, and show this object as a table in a table window.

Tables, histograms and two-dimensional tables are always opened as a table, for instance when they are double-clicked in the Catalog.

Point maps, annotation text objects, class/ID domains, class/picture representations, georeferences tiepoints and coordinate systems tiepoints are internally stored as a table and these objects can therefore also be opened as a table.

Note:

The option Open As Table is designed for experienced users. Opening an object as a table means that you can touch the object as it is stored on disk; you can see and edit the binary data files of an object, which are otherwise not readable, in ASCII now. Editing leads to changes with the risk of making an object unusable. Keep in mind that names and codes of domain items should be unique. Further it is not advised to edit the values in columns Ind and Ord of a domain as this can lead to serious problems such as missing domain items, wrong colors, wrongly linked attributes, etc.

The general idea behind opening these objects as a table is to allow the user to manually edit the object in table form, and to perform calculations with TabCalc on or with the columns in the table. For some purposes editing an object in table form might be quicker, easier or more precise, than using the point map editor, the annotation text editor, the domain class/ID editor, the representation class editor, or the georef tiepoints editor.

A special set of functions was designed to be able to calculate with XY-coordinate columns, color columns, etc. For more information, refer to TabCalc : special calculations.

Opening point maps, representations or annotation text objects as a table will look familiar to ILWIS 1.4 users because ILWIS 1.4 point maps, color look-up-tables and annotation text files were always stored as ASCII tables.

This dialog box appears:

when you choose Open As Table from the File menu in the Main window.

Dialog box options:

Select a table:	Select the object which you want to open in a new table window.
Directories:	If necessary, change the current directory.
Drives:	If necessary, change the current drive.

When the object is not open yet, it is opened in a new table window.

When the object was already open in another form, it is also opened as a table.

Tips:

An annotation text object is directly opened as a table by double-clicking it in the Catalog.
To open a point map, domain class/ID, representation class/picture, a georeference tiepoints, or a coordinate system tiepoints as a table, you can also click them in the Catalog with the right mouse button, then choose Open as Table from the context-sensitive menu.
You can also open objects as a table by typing the ShowAsTbl or the OpenAsTbl command on the command line of the Main window. For more information, see Appendices : ILWIS commands.
