DPS' Command LogiX is designed to provide travelling time
and distance information to other computer programs in the
most straightforward manner possible. It is a companion to
the more comprehensive Batch Route Planning System (Route LogiX
Toolbox) which provides a full route-finding service.
In its simplest form, Command LogiX reads an ASCII text
file (in a specific format) which contains two or more call
points and outputs a new file giving the time and distance taken
to travel the whole journey. Place names can be entered as:
- Postcode/zipcode
- Latitude/longitude co-ordinate
- Ordnance Survey Grid
Reference (valid only in the UK)
- Non-ambiguous place
name

This last option needs a little further explanation. Command LogiX
will recognise a valid postcode or numeric coordinate. Any other
entry will be checked against the extensive internal gazetteer in
an attempt to determine its location. Place names that occur more
than once in a database need to be reinforced by the appropriate
county or region name. As an example, the name 'Leeds' appears more
than once in the British database, so using this name by itself
would not be sufficient for a unique location. However 'Leeds, West
Yorkshire' renders the address unambiguous. The routine is fairly
intelligent, and would also recognise 'W. Yorkshire' and 'Yorks'
as valid county names.
