[ Security Exhibition Network Smart City ] In terms of smart city services and urban planning, the role of geospatial or geolocation technology is very important. Every smart city solution is essentially based on geographic data. In fact, most new-generation technologies, such as artificial intelligence and the Internet of Things , can only achieve the desired results if they run synchronously with the positioning technology.
In this article, we will reveal how the use of location technology can enhance smart city services, introduce some examples of smart cities supported by location technology, and explore application ideas for various location technologies.
Every physical object on the surface of the earth has a location. Location-based technology assigns attributes to the location, identifies how it interacts with other objects on the city map, collects data, and helps make better decisions.
So how does location intelligence support smart city projects? Before moving on to use cases, let's look at how cities are using location technology to become smarter.
How to maximize the value of positioning technology in smart cities
The implementation of geotechnology has enhanced all aspects of smart city services: transportation and transportation management, optimized energy use, urban marketing, real estate development, crime prevention and event management are the areas that have the most positive impact on the application of geospatial and geolocation technology.
For example, geofence-based services can be used to create virtual boundaries of physical areas, while this feature of smart cities can be used in many areas from security to in-store marketing. The arrival of 5G is expected to push urbanization to a whole new level of technology, and geo-fenced smart cities will also become ubiquitous.
IoT smart sensors , autonomous vehicles, and drones all use location intelligence to collect and manage data. In addition, digital twin technology and indoor positioning system (IPS) are also supported by positioning technology.
The combination of location-based services with urban demographic information and smart city analysis enables local businesses and city authorities to accurately determine their planning goals and understand the most pressing needs in urban communities. For example, a restaurant chain can use location intelligence to determine the best location to open a new store; police can identify areas where crime rates are rising to strengthen surveillance and more.
In other words, smart city services can be provided to the people who need them most, at the right time, at the right place.
Example of location-based services
To date, smart cities around the world are using geographic information systems (GIS) and location-based solutions to solve problems ranging from managing urban tourism to improving safety and healthcare.
▲ Track social media to prevent crime
Social media is geotagged and contains a lot of constantly updated information. In Huntington Beach, California, to strengthen crime prevention initiatives, police began using real-time social media location intelligence to track the use of keywords such as "fire," "firearms," and "fight." (From the Internet of Things home network) Location-based services in smart cities can also help point out potential crime locations and take appropriate action. Police also use location-based applications such as SnapTrends or Geofeedia to conduct investigations and help identify suspects.
▲ Using geographic information system to provide urban services to residents
Geographic Information System (GIS) technology has been used by urban communities for decades. In New York City, the LinkNYC kiosk offers free WiFi, charges mobile phones, and informs users of activities and services in the area. They have basically replaced traditional public telephones as urban communication networks in the 21st century.
▲ Geo-fence ensures safety
In Seoul, South Korea, smart geofences track the departure of children and elderly people wearing IoT GPS bracelets from designated areas. The system is integrated with the city's database to help find missing community members. These families also receive notifications and alerts, which increases people's sense of security.
▲ Advanced parking management
In densely populated urban areas, finding parking spaces has always been a challenge. In Barcelona, Spain, the Smart Location Service tracks information about available parking spaces and overlays them on a GIS map, enabling drivers to get real-time updates on parking options.
▲ Emergency Medical
A medical plan called Caalex, launched across Europe, is one of the most prominent examples of using smart location services. The system monitors citizens' biomedical parameters through wearable devices and notifies medical staff when someone is unwell.
▲ Comprehensive data platform
In Copenhagen, Denmark, smart sensors operate throughout the city. To prevent and address a host of issues such as traffic jams, air pollution, energy and waste management, the city is using data collected from city streets, vehicle GPS beacons, and citizens' smartphones.
Application of location-based technology in smart cities
Of course, the full range of location intelligence capabilities goes well beyond existing location-based services. So what are the other applications of location-based services in smart cities? Here are some practical ideas.
Disaster and emergency tracking: With the advent of 5G, advanced location intelligence will respond instantly to emergencies. A location intelligence system running in the background will automatically issue alerts about any activities that are out of the ordinary and potentially dangerous, and an emergency team will be dispatched immediately.
Crime prevention: With the development of hybrid location-based technologies, they will empower police and security services with advanced crime prevention capabilities. For example, indoor surveillance systems will be able to detect the exact location of people or objects in a building.
Advanced urban planning: The application of geographic information systems in smart city projects is not limited to providing geospatial data, but will also play an important role in future urban planning. In addition, the role of GPS in the development of smart city buildings will also be very important.
These technologies will enable engineers to create digital models and design residential areas in a way that helps make more efficient use of infrastructure and resources. Although modern cities are mostly the result of disorderly construction, future cities will be fully planned.
