Depending on the area that needs to be checked and verified, TomTom can opt to either send out just its field staff or deploy its mobile mapping vehicle if its an expansive area that needs to be covered. Field staff are typically armed with either a tablet PC and an iPhone. Using the tablet PC, they can make changes to the existing base maps and these changes can later be uploaded to their mapping department. The iPhone is loaded with a TomTom-developed app called Field Editor, which field staff can use to take photos of anything that is deemed important to note, such as speed limits, road signs, junctions and landmarks.
If the area is expansive enough, TomTom can choose to deploy one of its 22 mobile mapping vans worldwide. The vans are armed with an arsenal of equipment such as a Lady 360º camera that is programmed to take photos of the road and its surrounding environment at fixed distance intervals,and lasers that can measure road dimensions and determine road conditions and even road signs. The vehicle also has a gyroscope that measures the gradient and also the curvature of roads.
