  1. get xyz+ file
  2. remove points preceding 2006
  3. calculate time to next point
  4. calculate distance to next point
  5. pass through the list
    1. assign ID 1 to the first point
    2. continue through the points. If there is a time break more than ?? seconds, assign ID 2+
      (Now we have a list of potential lines)
  6. remove points with HDOP >= 8 and #SV < 4.
  7. pass through the list again for each subset of points with the same ID
    1. assign ID.1 1 to the first point
    2. continue through the points. If there is a distance break more than ?? ft, assign ID.1 2+
  8. Collect the point sets to create singlepart lines (for those points that have only 1 ID.1) and multipart lines (for those points that have multiple ID.1.
