Going Beyond the Street: Fusing Aerial and Mobile Mapping Data

Most people are familiar with maps, but may not realize they are made of combined geospatial data from the street and from the air. As ordinary citizens routinely use digital maps to navigate, Jakarto’s software is like Google Maps’ street view for professionals. It fuses aerial and mobile mapping data to provide a comprehensive model of your city.

Detailed map data will shape the future of urban planning. Mobile mapping is growing rapidly due to investment in smart cities and new technology for geospatial data. Digital twin companies like Jakarto enable municipalities to better understand and manage city assets.

Aerial data from unmanned aerial vehicles (UAVs or drones) and planes can complement mobile mapping data from cars to build an extremely precise model of any place. Artificial intelligence (AI) further expands the power of map data.

By analyzing the measurements made from the street or other sources, specific and trained AI can automatically do asset inventory. This makes city planning faster and more affordable while contributing to the development of a smart city. You can interact with the immersive city model and use its data throughout urban planning and management.

Aerial and Mobile Mapping Data: Building Blocks of a Digital Twin City

A digital twin city is a computer model of your entire urban area, including roads, trees, signs, and other elements. The model stores highly accurate geospatial data, maintaining the locations of objects for analysis and inventory. Jakarto can assess the data down to an astonishing precision of 1 millimeter.

Making a digital twin requires the underlying mapping data, which can be collected by street-level or aerial devices. The measuring equipment is mounted on a vehicle and carefully documents the contents of a city.

Geospatial data can then help municipal planners improve traffic flow, asset management, maintenance, and numerous other areas of activity. With the data, you can assemble an immersive 3D reflection of your city. Staff at different levels can then employ the map-based digital twin to streamline their work.

Street-Level Mobile Mapping: Establishing Insights Into the City

The data from the street represents what you can see driving through the city. This encompasses the roads, all street furniture, public trees, and other plants. However, it doesn’t include what’s hidden from the street, such as backyards, pools, etc.

Mapping your city from the street offers insights into the public areas with exquisite detail. For instance, Jakarto’s mobile mapping units employ a range of hi-tech sensors, including LiDAR and HD cameras, to acquire precise geospatial data.

The advanced technology making this feat possible includes lasers that bounce off objects, allowing the device to calculate distances. Along with width and height, the device can then place each measured point of an object in your city at an exact 3D location. This functions with high-definition imagery and GPS data to analyze all assets in the area.

Aerial Data: Total View of City Territory

Aerial data complements street-level data, as each approach excels where the other falters. While aerial data is typically lower-resolution than street-level data, it allows you to see into backyards. When combined, the two methods give you a complete picture of the city.

Aerial data acquisition involves sending a flying vehicle equipped with cameras to peer down over the city territory. As with ground-based observations, aerial measurements can be done with a range of tools including LiDAR and cameras.

Unmanned aerial vehicles improve mapping in several ways. For example, drones make the process much simpler than manned flights. This makes mapping less expensive, and more ground can be covered in the same time. UAVs also produce more accurate data, since they can fly lower to the ground than manned aircraft can.

Combining Mobile and Aerial Geospatial Data for Comprehensive Smart City Assets

While street-level map data and aerial map data each have their uses, they unite to provide the best of both worlds for smart cities. Street-level mobile mapping on its own only sees what’s visible from the road but includes precise details. Aerial mapping sees everywhere but in less detail. Together, they give you comprehensive geospatial data.

With the combination of street-based and aerial geospatial data, it becomes feasible to produce the high-quality digital twin cities increasingly rely on. Jakarto uses a strategic mix of data sources to offer unrivaled municipal data for your inventory. In conjunction with AI, this gives you the upper hand in managing city assets.

For example, AI-powered geospatial data can help manage an overhead power line network. It combines two-dimensional and three-dimensional data to reveal precisely where the electricity lines extend. The digital twin includes wires, poles, and equipment, so you can see where your assets are without rolling out trucks.

Aerial and Mobile Mapping at Work

When you use aerial and mobile mapping, you’ll have data working to provide a visual and spatial answer to questions about anything in your city. This one-two punch makes it easy to plan maintenance and construction from your office as if you were anywhere in the city in person.

The aerial map data provides context and breadth, while the mobile street-level data provides depth. Together, they yield a faithful replica of the city. You can use the digital twin from a laptop or other device. For example, Jakarto provides the easy-to-use cloud app Jakartowns to engage with city data.

Aerial and Mobile Mapping Data With Jakarto

Combining both aerial and street-based mapping technologies is the synergistic way to collect detailed geospatial data for smart cities. You get the intense detail of mobile mapping plus the complete coverage of aerial mapping.

Jakarto leads the industry with its innovative approach to bringing together not only aerial and mobile mapping but also artificial intelligence. The result is a high-quality digital twin of your city.

Mobile mapping produces high-definition, precise, and rich data with dense point clouds. Aerial mapping sees what you can’t from the road. Keeping the street data and patching it with views from sky is the best approach, fusing aerial and mobile mapping data.
