3rd Party Routing

Using 3rd party databases can be sometimes quicker to use while routing.

Select Applications > Routing Tools > Settings > 3rd Party Routing.

OSRM databases for Greater London and Hertfordshire are included as standard in SIS 9 Desktop. Select either one from the drop-down menu.

• To add a new one, click Add Database.
• Use the file browser to select any relevant OSRM files.
  
• Click Close.

Ensure you have exported your desired OS products into a OSRM database. Use the Utilities tool in Cadcorp GeognoSIS to do this.
