Managing Header Definitions

 

 

 

 

TPC calls the name at the top of a column of data, a header.

Headers are used in

drawing tables

CSV files

Shape files

 

Edit Drawing Table Column Headers (3:15) - We edit the column names for a curve table and save them to a header file we can recall for any other curve table.


Drawing Tables

In the section of the Curve Table shown here, the column headers are Curve, Chord Bearing, Chord Dist, Radius, Arc, etc.  The user has modified the names of the Chord Bearing and Chord Distance headers plus added a line break character / to split the labels onto two lines.  See Editing Column Names.

 

This change made to this curve table affect just this table in this drawing.  However, you may want to

save this format for the city or county that requested it and re-use it when you work for them again

save this format for use within your organization and share it with others

make this your new format and use it to update all your existing drawing templates

 

As you can see, there are lots of reasons for saving and reusing a format like this.

See Editing Column Names.


CSV Files

This example focused on drawing tables, the headers are used in CSV files used to import and export survey data.  Some of examples of these are Bad Elf (CSV), Emlid (CSV) and GNSS (CSV).

TPC provides default header definitions for all of these, but if you need to, you can modify their header definitions, just like you did the drawing table, and save those definitions for reuse.

See Editing File Headers.


Saving and Opening Your Header Definition Changes

You will use the File Open and File Save buttons right below the list of header definitions to save and reuse changes you make.

Save

Left click the Save icon (blue floppy disk) to save the current header definitions so a header definition file (see below).  TPC will display the File Save dialog and take you to the default program data location.

Overwrite an existing header definition file or enter a new filename that describes the definition you are saving and save the file.

Open

Left click the Open icon (yellow file folder) to open an existing header definition file.  Once opened, TPC will read the definitions into the dialog as if you had changed them manually.


Header Definition Files

TPC stores header definitions in .dat files in the \Headers\ sub-folder of your program data folder.  When you use the Save and Open icons shown with the red arrow above, TPC accesses this sub-folder.


Default Header Definition Files

The \Headers\ sub-folder includes header definitions files that end with Default.dat.  These are the default definitions for that CSV filter or drawing table used in TPC.  These files are installed with TPC and are set to Read Only on installation.

If you try to modify your own header definitions and get things so messed up you can't figure it out, feel free to start over by opening the corresponding Default.dat definition file and starting over.
