Mobile Mapping

Accurate Enough for Urban Areas
Mobile mapping systems can quickly and accurately acquire geo-data at a high level of detail. Features especially beneficial in urban areas where construction and layout rapidly change and traditional surveying is rendered virtually impossible, and not only during rush hours. A mobile mapping system consists basically of a vehicle equipped with positioning sensors and laser scanners. It may also have mounted digital cameras, as with the Topcon IP-S2 described in this article, or other sensors such as thermal sensors and ground-penetrating radar. The very core of a Mobile Mapping System (MMS) consists of a positioning system comprising a GNSS receiver... (read more)

Mobile Mapping System

Gispro have successfully implemented Land Based Mobile Mapping System (MMS/MLS). The system consists of Riegl laser scanners, digital videoscanners and ground-penetrating radar. Positioning and orienation are established using POS420 and GPS receivers with IMU and DMI, built onto a car.   The exact configuration is as follows: 3 laser scanners from Riegl. Two VZ-400 scanners are placed on the sides of the car and can be easily removed and used for static scanning. Between them there is a VQ-250 "Full Circle" scanner. These are currently the most advanced laser scanners in the world. 6 digital video cameras Arecont Vision allowing... (read more)

Topcon Mobile Mapping Move

Topcon Positioning Systems (TPS) Latin American distributor Geomatic Instruments Corporation (Geincor, Peru) is now offering the IP-S2 mobile mapping system. Geincor took ownership of the system in April 2011.     The company’s business plan is two-fold: Geincor will act as a sales agent for customers wishing to purchase an IP-S2; for customers and agencies who need comprehensive 3D data, the company will provide collection services.   The dealer / service provider model will enable the company to serve a wide range of Peru's mapping needs.   “Mapping the nation's historic areas is one of our priority goals,” Nelson Meneses,...

Underground Mobile Mapping

Laser Scanning and Imaging of Corridors in Japan
Common mobile mapping systems heavily rely on positioning using GNSS. However, concrete, soil and other materials block GNSS signals, thus impeding their use when inspecting pipelines, subways or other underground corridors. Furthermore, such corridors are often narrow, which requires the system to be compact. Here, the author describes a platform equipped with laser scanners and a camera which has been developed in Japan for mapping a wide variety of narrow underground spaces. Regular inspection of underground corridors is important to detect deformations and damage. The success of above-ground mobile mapping systems (MMSs) triggered us to design an MMS for use...

Mobile Geological Mapping Software

GAF has released a free trial version of GeoRover, a mobile geological mapping software, developed on the basis of experience gained from real geological mapping field work. The software integrates GPS navigation, GIS functionality and spatial raster data management in one tool. This allows field mapping experts to work smarter and faster - thus enhancing productivity and improving efficiency significantly. In early 2003, GAF AG defined a new method for geological field work with the launch of the first version of its GeoRover software, which was based on a modern digital geological mapping approach. Using the experience gathered in different... (read more)

Mapping with Mobile Lidar

High Speed, Accuracy and Density
The use of Mobile Lidar systems enters the scene when large areas have to be surveyed at accuracy and resolution exceeding those available through aerial photogrammetry, and when using static Lidar is impractical. The Lynx Mobile Mapper captures high-accuracy, high-density points, allowing easy and precise identification of objects. In 2006 Sineco S.p.A, an Italian engineering firm belonging to the ASTM Group, began collaborating with Optech Incorporated, the Canadian manufacturer of laser-based imaging systems, to develop a mobile Lidar system. The first prototype, ready in early 2007, combined two ILRIS-3D laser scanners with a position-and-orientation system (Applanix POS LV 420). This... (read more)

Indoor Mobile Mapping Solution

Trimble's Indoor Mobile Mapping System (TIMMS) is a manually operated push-cart designed to accurately model interior spaces without accessing GPS. It consists of 3 core elements: Lidar and camera systems engineered to work indoors in mobile mode, computers and electronics for completing data acquisition, and data processing workflow for producing final 2D/3D maps and models. The models are geolocated, meaning that the real-world position of each area is known. A walk-through of an interior space with TIMMS delivers full 360-degree coverage. The spatial data is captured and georeferenced in real time. Thousands of square feet are mapped in minutes, entire buildings... (read more)

Indoor Mobile Mapping Goes Mainstream

In his previous column about the future of indoor mobile mapping, Felix Reinshagen made the case for why this technology was on the brink of widespread adoption. That was just over a year ago, and a lot has changed since then: brisk expansion of the products and services on offer, together with a widening field of applications. So after another incredible year, Reinshagen has written a new column outlining why he believes that mobile mapping is well past the tipping point and is about to go mainstream. The emphasis now is on assessing data quality and establishing universal standards in... (read more)

Image Anonymization for Mobile Mapping

Achieving Legal Compliance of Mobile Mapping by Anonymizing Images
Large amounts of personal data, such as faces and number plates, are collected during mobile mapping. Receiving consent from individuals for large-scale data collection is not feasible but is required by law in certain countries. Anonymizing images not only eliminates the need for consent but also increases trust in companies who conduct mobile mapping. Privacy concerns in mobile mapping go back to 2010, when the Belgian Privacy Commission published the “Recommendation on Mobile Mapping”.  The scope of the recommendation covered not only applications such as Google Street View but also other types of mobile mapping such as mapping by public...

The Age of Mobile Mapping

Looking back over the past 30 years, it’s hard to believe just how far we’ve come in such a relatively short space of time. Geomatics students in the mid-1980s were exposed to GPS test satellites, the first GPS receivers and the enormous potential that GPS offered the geomatics community (who had already perfected what could be done with the Transit satellite system). With unprecedented absolute accuracy and an impeccable timing mechanism, GPS clearly offered a quantum leap in geomatics capabilities. Two decades later, Lidar – and in particular mobile terrestrial Lidar – seemed to represent the next quantum leap in... (read more)
