Application Info

Top  Previous 

For the technically interested user, here is a bit of information about the application.

 

It was developed with Delphi 11.3 using a few 3rd party libraries:

 

TurboPower Abbrevia (gz file unzipping)

OXML (fast xml file parsing)

Parts of our own RW Net 4 is used for gisfile writing and more.

EFAL is used for TAB file writing.

 

If you have used the older ITN converter you will see that it is now at least 10 times faster.

The main reason is the data structure from Ordnance Survey is much easier to work with.

But we are also using a faster library for XML parsing than MSXML.

At the same time the data handling has been refactored, so the code is much easier to read and maintain.
