Introduction to Mobile Mapping
Mobile mapping systems have developed gradually in the last 20 years, mainly in academic research establishments. Recently, many of commercially operating systems have emerged. These were mostly one-off systems that were developed in-house by the companies that serve them. Most of them were used to collect data on road infrastructure or building facades.
However, some huge companies like Google, Tele Atlas, and NAVTEQ have adopted the technology on a large scale over the past two or three years and introduce a significant number of mobile mapping vehicles for their imaging and mapping operations. This has led to further rapid development of mobile mapping technology, which can now be considered too established and proven.
The benefits that mobile mapping systems can offer are high accuracy, improved protection, and increased safety. In a world where competition between institutions has become a gauge, the collection of accurate and productive data has become the main factor for many institutions.
Data collection is crucial for financial institutions and has become critical in numerous sectors such as emergency services, agriculture, insurance, construction, etc.
Realizing the importance, multiple companies are developing solutions that can collect geospatial data from a mobile vehicle. These mobile mapping systems are typically equipped with a range of photographic, radar, laser, LiDAR, or remote sensing systems, including synchronized navigation sensors and mobile platform-mounted imaging sensors. The main output of these systems is GIS data, digital maps, and georeferenced images and videos.
Using these systems, we are capable of capturing about 1,000,000 measures per second. Such georeferenced data points can be used in combination with positioning equipment to generate accurate, 3D digital elevation models (DEMs) or Digital Terrain Models of almost any environment.
Smart cities have become a buzzword increasingly for many smart city projects worldwide. India has 100 smart Cities in its plan. As a leading provider of Geospatial solutions, Genesys has been at the forefront of such smart initiatives. Genesys is implementing the newest technology – Mobile LIDAR mapping, 3-D rendering, and visualization – to merge existing mapping systems into a common 3-D-enabled platform to provide a smarter, more space-connected information network would benefit both citizens and increase revenue generation for the city.

This article will discuss some of the main application areas where the latest geospatial technologies can be used in smart cities. Our services will help smart cities enhance maintenance and operating costs for city roads and other city infrastructure and help utility firms map and set up their networks to significantly enhance citizens' services.
The wealth of information generated by 3-dimensional LiDAR mapping associated with geospatial analytical tools consumed over devices ranging from computers to smartphones will equip city planners and designers with the analytical tools needed to address complex challenges in the smart city environment.
Mobile mapping applications
Aerial mobile mapping:
As mentioned, Mobile mapping is a massive data collection system that simultaneously uses several capture methods. Generally, it is usually worked with a vehicle-mounted LIDAR system, which moves at a constant speed to scan the terrain. The result is the generation of a cloud of points in the environment.
However, the traditional Mobile Mapping technique loses some of the information by not having direct eye contact with certain elements that may be relevant. For example, if we are scanning a town, we will not have the point cloud of the roof or the canopy of the trees, or if we are scanning a road with steep slopes on its sides, we also lose part of that information.
GEOTECH3D-maps combines drone technology with Mobile Mapping, capturing that information that we did not get with the traditional system. To do this, the drone flies following the Mobile Mapping vehicle, photographing the environment from above.
Our team experts combine the information captured by the drone with that of the vehicle through specialized mobile mapping software—the result: a much more complete point cloud.
Emergency response planning:
Mobile mapping systems allow rapid data collection so that conditions on the ground are accurately assessed.
Road-mapping and highway facility management:
GPS combined with digital camera systems make it possible to update road maps quickly. The same system can be used for efficient road condition surveys and facility management. The technologies of laser scanning, mobile mapping permit the collection of full 3D data on slopes, banking, etc.
Innovators in Smart Cities use 3D technology as an enabler.
True smart city adopters don't see the technology as an endpoint but as a key enabler for practical solutions to boost the urban realm's performance. Perhaps the smart city will no longer be referred to as such in the future since the tech is so unobtrusive and incorporated into people's daily lives.
Nowadays, brilliant cities still feel like a somewhat futuristic concept. But the puzzle pieces are gradually coming together and finding and creating the missing ones. Today we'll look at how 3D modeling technologies and 3D maps play an increasingly important role in harnessing smart city potential.
How 3D technology makes cities smarter
While there are many smart city components, 3D visualization is becoming increasingly important to make this concept accessible to a wider audience. To streamline urban planning and measure impacts of new developments and public services, Smart 3D city modeling is now being developed by cities such as Hamburg, Helsinki, Chicago, and London.
For example, the City of Helsinki developed The smart 3D city model and constructed it in OpenGL format to add a layer of intellect and BIM Technology to the 3D geometry. The model includes semantic information about more than 80,000 buildings, as well as land and waterways.
Architects are invited to insert BIM models of the proposed buildings into the model to calculate the impacts on factors such as wind movements, sunlight, and traffic.
The ability to illustrate the scheme and its impact in the context of a broader model is in stark contrast to how the construction industry operates at the moment, with urban planning and construction/infrastructure design often treated as separate entities.
This siloed approach increases the possibility that topographic surveys and utility surveys will be duplicated. The ability to build and keep data in a single city-wide model could lead to significant efficiencies.
3D city models help solve challenges in the real world
With the evolution of smart city thinking, it is not unreal to forecast that many city's functions will be managed one day with highly detailed 3D models filled with GIS data and living sensors from buildings and infrastructure to provide an accurate picture of the city in real-time.
In this area, the city of Singapore leads the field. It has begun developing its own dynamic 3D digital model, a city's 'digital twin' that integrates data from the Internet of Things devices with dynamic real-time data, including the Internet and other sources.
The model would allow users from different sectors to create sophisticated tools and applications, test-bed new ideas and services, and study innovative technology to solve the city's emerging challenges. It is an exciting vision for the kind of brave new technology in the not too distant future we will live in. Contact Us
