Edit topic file

General

The window general contains the name, the location of the topic file and the file for configuration, the coordinate system used and the filetype.

Scale determines the range within which the data of the topic file is visible on the map. With opacity you can determine how well the data should be visible.

It is adviseable to use the same settings for screen and printer (this can be done by ticking the box apply for printer). This way a printout will look the same as displayed onscreen. Alternatively the box can be left unticked and settings for the printer can be set individually.

Files

The window files contains the individual files containing the information of the corresponding topic. In this window files can be added or deleted. The extent of these files can also be calculated here.

Add new file (all formats)

This button is used to add geodata from one or several files to the topic.

Add layer from server

This button is used to add geodatalayers that are provided by a WMS- or SDE-server.

Delete current entry

Deletes the currently selected file or layer.

Build extent for all items

Clicking this button determines the geographical extent of the file based on the integrated georeference. This helps TMC Studio load and display the data more quickly. Files whose extent has been been calculated are displayed with a green tick .

Display

The appearance of the Display window depends on the data that is being processed. The data in question will usually either be raster- or vector data.

Raster data

Here you can

• adjust the RGB-values
• brighness & contrast
• ...
• choose to set certain colours to transparent
• choose form a set of prdefined settings

Vector data

Vector data - Label

Vector data - Gradient

Feature

In the window feature you can decide which information is diplayed in the window Topic Information and choose which attributes are used as lables.

Fieldname

This column contains the names of all the attributes in the attached geodata.

Type

Describes the fieldtype of the corresponding attribute field. S = string (textfield); N = numeric (field for integral numbers); F = floating (field for numbers with commas); D = date

Active

For an attribute to be displayed in the window Topic Information, the corresponding box needs to be ticked. In the given example, only NAME would be displayed.

Description

If the name of the attribute is not clear, an alternative description can be entered here. Any text entered here will be displayed in the window 'Topic Information'.

Unit

Here you can enter the unit of the attribute (p.ex.: cm, litre, kg etc.).

Format

Because they are considered to be text, numbers by default are not sorted by value but by digit (1, 11, 112, 12, 2 instead of 1, 2, 11, 12, 112). To remedy this, a row containing numbers can be set to 'number' by double clicking on the field and opening the dropdown list.

Catalog

Clicking on the catalog button while an attribute is highlighted opens the following window:

In this window the individual values of the highlighted attribute are listed on the left-hand side. On the right-hand side they can be attributed with new values or names. The list of these names can be saved as .xls file (by clicking on the excel icon) and can be retrievd again via the folder icon.

The new names/values should be chosen sensibly. This can best be checked by opening the window 'Topic Information'.
