Abstract
Mobile Mapping Systems (MMSs) are made using sensors like, GPS, IMU and laser scanner. These systems are considered fastest and most reliable to capture high resolution and accurate three-dimensional information along a corridor. Quite a number of researchers have attempted to verify the accuracy of MMS through field experiments. However, there is limited literature available explaining the contribution of different sensor components to the total error budget or providing a statistically accurate estimate of total uncertainty in data. Further, there is no published literature available that can guide towards the selection of optimal set of sensors for developing an MMS to generate data of desired quality. This research paper demonstrates the effect of inherent sensor uncertainties on the overall error budget of an MMS. These errors are studied in isolation and in coupling with other errors. Further, a few guidelines are provided for selection of optimal sensor components and how these components control the system accuracy.
