    Default Anyone have an idea of what percentage of US roads aren't mapped

    This question came up from folks in the field who noticed roads that aren't in the StreetMap network. I realize not all roads are in the geometric network but does anyone know where I can find documentation on about what percentage of US roads are included in the network?

    Chris,

    Not sure if there is a hard and fast percentage number for US roads that are *not* included. The discussions always going to the data documentation and finding out the vintage/year of the data. For example link below there is a section regarding the TeleAtlas vintage (pages 12(5)).

    Always tough to answer those types of questions though providing vintage information as well as when data is planned to be updated helps. Or also creating a support incident so the missing roads could be documented is also helpful.

    Regards,
    Jason R.
