Link Editor menu → Import Network Database From Shapefile
In this window you specify all necessary information to import a network shapefile to your tmcStudio database.
Shapefile
- Click on the folder button
and select the shapefile containing the network data you wish to import to your database.
Link ID
- Select the field of your shapefile that contains the ID for the segment. It is mandatory that your network table contains a unique ID for each segment.
Link Name
- Select the field that contains the street or road names; optional but recommended.
From Node
- Optional and with no effect on linking; field with information on the from nodes.
To Node
- Optional and with no effect on linking; field with information on the to nodes.
From Segment
- Optional and without effect on linking; field with information on the from segments.
To Segment
- Optional and with no effect on linking; field with information on the to segments.
Link Type
- Select the field in your shapefile that contains information on the road type. Often it is named FRC.
Link Type Filter
- As soon as a Link Type has been specified, this field will display the road types available in the shapefile. Select the road types you wish to import by flagging them. Note that if you select 1, 2 and 3 for instance, you will be able to import 4 and 5 later.
Connection Settings
- If you want to import the data to an existing database select here the database
Create Database: If you want to create a new database select here where to store. With Firebird local
it must be always on a local harddrive
Delete existing data If you import in existing table you can chose if existing data in the database should be
in network database: deleted. If you want to add FRC 5 and 6 after you already imported FRC 1-4 then this
field should not have a flag
Depending on number of Segements that will be imported this task can take several hours. An approximate
estimation will be shown in the Import Screen, it will also show how many segments have been already
processed.
