Link Editor

The Link Editor access level grants access to the Link Editor menu and all functions contained by it.

Import from Exchange table

The format in TMC Studio is different from the former version. Therefore you will not be able to open the database created with TMC Editor in TMC Studio. You have to create a new database from the exported tables as Exchange Format. TMC Studio is able to import from Exchange Format ANSI and UTF-8.

Start TMC Studio

Select 'Import Location Table Exchange Format into new database'

Database file: Double click. Click on folder icon. Input database name and select where the database should be stored. When working with a local Firebird database, it must be stored on a local hard drive.

Source file: Double click. Click on folder and select exchange file if it was delivered as ZIP-File.

Source directory: Double click. Click on folder and select the directory where the DAT-Files from the Export Exchange are stored.

Run semantic checks: Ticking the box results in semantic checks being run after the import of the files.

In order to be able to press the OK button database file, source file and source directory must be defined.

Structure of INI file

TMC Studio will store data in two INI files. One INI file contains data from the application!. This INI file is always located in the directory where the EXE file is installed.

The other INI file is always stored toghether with the database and has the same name as the database. This INI file contains the configurations and setting that you will input into the software menue-tools-options. It is recommended to not manually change this file.

The INI file of the application is delivered with the software. Normally there will be ine INI file per country you have licensed. The structure looks as follows:

[GeoLogix]

ProjectName = TMC Country Y If you have more than one country, this is the name shown in the selection when starting TMC studio.

UserProjectRegistryPath = Country Y Personal settings will be stored under this name.

ErrorSendMode = 2 Should the software crash, you can send us an error message.

[About]

Name = Customer X

Serialnumber = N0QwQ-TRw Name and serial number are created by us and your license is registered with this information. Do not manually change this information.

[Database]

BSDatabaseType = FIREBIRD_LOCAL Normally you will work with Firebird local database.

User_Name = sysdba Standard for Firebird, don't change.

Password = masterkey Standard for Firebird, don't change.

Charset = UTF8 Standard for Firebird, don't change.

Define Network database for attributing map liks

To be able to link TMC Paths and Map, you will require the additional license for these functions. Once you have these licences go through the following steps:

Menu → Link Editor → Import Network Database form Shapefile

Shapefile: Double click. Click on folder and select the shape file with the network data.

Link ID: Select the field that contains the ID for the segment. It's mandatory your network table contain a unique ID for each segment.

Link Name: Select the field that contains the street names; optional, but it's use is recommended.

From Node: Optional and has no effect on linking - field with information from node.

To Node: Optional and has no effect on linking – field with information to node.

From Segment: Optional and has no effect on linking – field with information from Segment.

To Segment: Optional and has no effect on linking – field with information to Segment.

Link Type: Select field that contains information regarding Road Type. It's usually named FRC

Link Type Filter: The filter will show which road types are available in the shape file. You can select all types for import or limit the import certain types. If you select 1, 2, and 3 you will be able to import 4 and 5 later.

Connection Settings: If you want to import into an existing database, choose it here.

Create Database: If you want to create a new database enter the destination here. With Firebird local it must always be on a local hard drive.

Delete existing data in network database: !!

Depending on the number of imported segments this task can take several hours. An approximate estimation is shown in the import screen. It will also show how many segments already been processed.

Configuration of the Link Editor

Menu → Tools → Options → Link Editor

Enable: When using Link Editor this box should be ticked Connection Settings: If you imported your data from Shapefile, these setting should already be in order.

• Database Type - must be Firebird (local)
• Database - click on folder to select database
• User Name - must be sysdba
• Password - must be masterkey

Layer Properties: Configuration of the network layer, see next entry.

Network Cache File / Directory: Define where the cache file will be stored.

Display Network Link: Define the color and pattern of network links on the map.

Display TMC Link: Define color and pattern of TMC links on the map.

Layer Properties

Network database contains linear data. Here you can define how the various roadtypes should be represented on the map.

Name: Define name of the level.

Visible at scale from/to: Define the scale from where to where the individaul levels are visible.

• It makes little sense showing all levels constantly since this slows down the program. It is therefore sensible to define different parameters depending on the road's importance.
• For Instance: Motorway from 0 to 500'000; Main roads from 0 to 100'000; Secondary roads from 0 to 50'000; Urban roads from 0 to 25'000

Transparency: Can be kept at 100.

Filter: Set 'ROADTYPE =' and then select road level.

Lines: Define color and pattern.

Configuration for Routing

Menu → Tools → Options → Link Editor → Routing

Define a cost factor for the various road types. It depends on the structure of your network what makes most sense and gives the best results. As soon as you use the routing function you will see if the results make sense.

Creating and clearing Cache Files

Menu → Link Editor → Routing → Create Cache File

This function MUST be performed after the creation of a network database. Without this the performance of Routing will be very poor. Depending on the number of segments in your database this function will take several hours.

Menu → Link Editor → Routing → Clear Cache File

Use this function if you import new data into your network database. After this is done start 'Create Cache File'.

Importing Network Links

Menu → Link Editor → Import XML

If you had already defined TMC Links in the TMC Editor that information must be transferres to TMC Studio with Export XML. This will create an XML File containing all the information.

Source File: Double click. Click on folder and select the file you want to export. The program will look for ZIP files by default, so change it to XML.

Clear Existing Links: Tick this box if you want to delete links that have already been created in the database. If you don't tick the box the link information in the database will be kept if it doen't already exist in the XML file. !!! To be able to click the OK button you will be required to click the field, even if you don't tick the box.

Depending on the number of TMC paths defined in the XML file this function can take several hours.
