To exclude strings

For some LandXML string roads, the centerline alignment does not form part of the road surface and must be excluded. In addition, some roads may include strings that go back on themselves. Sometimes these strings are unrelated to the road design (for example, a fence line), and should be excluded. In other situations the string may be valid (for example, a curb return), and should remain part of the road. However this will mean that staking the string will result in staked points that have duplicate station values.

To exclude strings from the road:

1. In the map, tap the LandXML string road to select it and then tap Edit. Alternatively, tap and select Define / LandXML road, select the road to edit and then tap Next.

   If the road you want to edit is not shown in the map, tap in the map toolbar to open the Layer manager and select the Map files tab. Select the file and then make the appropriate layer(s) visible and selectable. The file must be in the current project folder.

2. Tap Exclude.

3. From the list, select the strings to be excluded. Excluded strings have a checkmark by their name and are shown blue in the map. To aid selection, the name of any string that does go back on itself is listed in red text.

The Roads software automatically excludes the centerline when the alignment strings are defined by one of the following:

• break lines where there is a break line at zero offset.
• irregular lines where there is an irregular line at zero offset.
• irregular lines and the file includes a property record to exclude the centerline.

To include a string for these roads, in the map tap Edit and then tap the Exclude softkey. Tap the string name in the list. The checkmark is removed, indicating the string is no longer excluded.
