article the acquisition of survey data is a time-consuming thing in itself, but it can be even more difficult when the data has to be acquired in a place that has a lot of traffic. dutch company geomaat found a solution that not only reduces surveying time, but also is suitable for heavily trafficked areas. by lambert-jan koops streetmapper 360 for acquiring topography geomaat acquires 3d data without traffic obstruction geomaat is an independent surveying company founded in 2002. from its head office in groningen, the netherlands, the company performs a variety of different projects, from measurements on the ground, road and water construction, and profile measurements for water boards to gps volume definitions and topographic measurements for communities and developers. geomaat was the first company in the world to buy the streetmapper 360 system. this is a surveying system that can perform 360-degree laser scans from a moving car. complete motorways and urban areas can be surveyed at speeds of more than 100 kilometers per hour. director jolle jelle de vries explains why the company bought this system: right from the start geomaat has been engaged in innovative solutions, and every year we look for new methods and equipment that can sustain our work. three years ago we started with surveying 3d data using gps stations that were mounted on quads, so we already had experience with mobile surveying systems. in 2008 we first came into contact with the supplier of streetmapper 360, the english company 3d laser mapping, and after going through trial trajects in may and june we bought the system in november. where the former streetmapper solution made use of four stationary scanners, our system uses two rotating laser scanners. also, our system offers more options because the resolution is higher than the previous version. 34 october/november 2009
