Excluded and included strings in LandXML string roads

The software automatically excludes some strings when the LandXML string road is used in Trimble Access Roads.

Alternatively, the LandXML string road may include some strings that you want to exclude. For example, for some LandXML string roads the centerline alignment does not form part of the road surface and must be excluded, or 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.

You can include any previously excluded strings as needed.

Any changes made to the status of the strings in Trimble Access Roads are written to the LandXML file.

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.

  1. In the map, tap the LandXML string road to select it and then tap Edit.

  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.

To include a string that you have excluded or that the software has automatically excluded from a LandXML string road:

  1. In the map tap Edit.

  2. Tap Exclude.

  3. Tap the string name in the list.

    The checkmark is removed, indicating the string is no longer excluded.
