Created page with '== Introduction == TUFLOW requires the data attributes of each specific table to match those written with the .tcf command: <tt>Write Empty MI Files </tt><...'

New page

== Introduction ==
TUFLOW requires the data attributes of each specific table to match those written with the .tcf command: 
<tt>Write Empty MI Files </tt> <tt>==</tt> <tt>..\model\mi\empty</tt> 
There are however a number of example of where modifying the names, types and order of these data attributes is useful. Examples include:
* Adding extra columns after the TUFLOW attributes, additional columns are ignored by TUFLOW. It can be useful add a comments field.
* Vertical Mapper inspections add additional columns, it may be desirable to remove or re-order these.
* Manipulate data into a TUFLOW format.

== Changing Data Attributes==
To change the data attributes of a table, use the menu item ''Table >> Maintenance >> Table Structure''. When prompted select the table that you wish to modify. This will bring up a list of the data fields, the type of data (Character, Float [numeric], Integer...). Within this interface additional attributes can be added, removed, re-ordered and the data type/length can be changed. 
In the image below an additional data field with the name "Comments" has been added below the standard 1d_nwk attributes, this is a character field and can be used to store strings up to 250 characters in length. This field is ignored by TUFLOW and is an excellent place to store comments. 
In the second image, the ''Elevation'' column in a 2d_Zpt removed, it has been replaced by ''DEM_M01_1'' which was inspected using Vertical Mapper (see [[Tute_M01_Inspect_Zpts_MI_Vertical_Mapper | Tutorial Module 1, Vertical Mapper]]. 
'''WARNING''' Removing data fields can not be undone.
