The Advanced Settings dialog box is displayed by pressing the Advanced Settings button on the main dialog box:
The advanced settings include three Route Settings. First, you can set the maximum search distance ("Search distance when matching locations to the road network") when matching a coordinate with the road network. Ultra MileCharter will only search for a road node within this distance of each requested coordinate. The closest point found will be used. Any locations that do not have any road nodes within this distance will be considered 'un-routable' - i.e. too far from a road.
If the route could not be found, and Ultra MileCharter detects this was because the location matched a short section of road network that did not connect to the main road network, then it will attempt to try the next closest piece of road network. This might occur with a disconnected section of track, or an alley system in a pedestrianized city. You can disable this behavior by setting the Simple Road Search check box. This will tell Ultra MileCharter to only try the closest piece of road segment and not to try any others. It is quicker, but it will fail to find more routes.
The road packs can be quite large and take time to load into memory. You can tell Ultra MileCharter to pre-load the road pack before processing by setting the Preload Road Data check box. This will tell Ultra MileCharter to load the road data as soon as it has the name of a valid road pack. Note: This can cause the main Ultra MileCharter dialog box to become sluggish whilst the road data is being loaded.
There is currently one User Interface setting. By default a dialog box with timing information (i.e. how long processing took) is displayed when processing has completed. This has to be dismissed before you can return to Ultra MileCharter's main panel. Clear the Display timing dialog box on completion check box if you wish to disable the timing dialog box.
