Abstract

The latest development and evolution of surveying and mobile mapping technologies opens new avenues for the acquisition, update, fast and online processing of data. Currently mobile mapping systems are supported by a series of advanced technologies, including GPS and Inertial Navigation Systems (INS), imaging sensors of high-resolution CCD, SAR, multispectral and hyperspectral sensors, portable computers and highly intelligent processing/automation algorithms. This paper outlines recent developments of micro-GPS technology and integrated mapping systems, including accuracy, integration with GIS and communication techniques. The definition and history of the Mobile Mapping System (MMS) is reviewed and briefly outlined. Advancements in low-cost, micro-GPS technologies are emphasised. Some new advancements of the current MMS will be reviewed to demonstrate recent progress and future trends of development. A few commercial MMSs are also assessed.
