Enhancing Geospatial Insights with Mosaic Mobile Mapping and Mapillary’s Seamless Workflow
Modern mapping needs real-time data for effective asset management and urban planning. This is crucial for both public and private sectors involved in road, network, or utility management. However, data collection and analysis have been challenging.
Mapillary aims to solve this by refreshing map data using street-level imagery. They’ve expanded by adding 42 new object as point features extractable from imagery, enhancing map detail. Initially focused on traffic sign recognition using advanced tech, Mapillary has grown towards universal traffic sign recognition with global contributions.
The integration of Mosaic’s Mobile Mapping Camera Systems with Mapillary is set to advance geospatial data collection and analysis. Mosaic’s systems ensure precise data capture and processing. This collaboration simplifies workflows, from data capture to actionable insights, promising significant impact in the geospatial and asset management fields.
The Mosaic Mobile Mapping Camera Systems
In the geospatial domain, the accuracy and granularity of data are as crucial as the efficiency with which it is collected and processed. The Mosaic Mobile Mapping Camera Systems are engineered to excel in all these aspects, providing a robust solution for modern-day mapping challenges.
Features of the Mosaic Camera System
Built-in GNSS, GPU, and CPU
The heart of the Mosaic camera system is its integrated Global Navigation Satellite System (GNSS), which ensures precise geolocation data of each image captured.
Accompanying the GNSS is a high-performance Graphics Processing Unit (GPU) and Central Processing Unit (CPU), which are pivotal in ensuring that the device is a fully standalone unit, eliminating the need for a bulky computer within the vehicle during data capture.
Hot Swappable SSD for Data Storage
Storing the voluminous data is a breeze with the on-board Solid State Drive (SSD) unit, which not only provides ample storage but also ensures quick data retrieval and transfer.
Data Captured by the Camera
The following is the data captured and stored onboard the Mosaic 51 and Mosaic X camera systems. Note that due to the on board storage, there is no need to use a computer or workstation within the vehicle during data capture, easing the process and eliminated points of failure.
- This file records the timestamps of each frame captured, creating a chronological log that is crucial for syncing with geospatial data.
- The raw output from the GNSS receiver is stored in this file, usually recorded at a frequency of 10Hz, providing a granular view of the geospatial trajectory.
- An interpolated and synced version of the geospatial data, this file provides the position of each captured frame along with the time of acquisition, ensuring a coherent dataset.
- Six Video Container Files
- Each of the six video container files corresponds to a camera sensor, capturing the surrounding environment in high definition from multiple angles, thereby creating a comprehensive 360º imagery.
The meticulously designed Mosaic Mobile Mapping Camera Systems are not just data collection devices but a comprehensive solution designed to sync effortlessly with Mapillary’s platform. By addressing the needs for high-precision data capture, secure data storage, and an easy-to-use device, these camera systems are geared to propel the geospatial and asset management fields into a new era of efficiency and accuracy.
Seamless Workflow from Data Capture to Mapillary
The combination of Mosaic Mobile Mapping Camera Systems and Mapillary’s platform orchestrates a streamlined workflow that transitions smoothly from data capture to insightful analysis on Mapillary. This synergy alleviates the traditional bottlenecks associated with geospatial data handling and analysis.
Ease of Capturing Comprehensive Geospatial Data
With Mosaic camera systems, capturing street-level imagery becomes a straightforward task. The cameras, mounted on vehicles or carried by individuals, record the surroundings in a 360º view, generating a rich dataset that forms the foundation for subsequent analyses.
Importance and Application of the 360º Imagery
The 360º imagery captured is pivotal for a myriad of applications ranging from asset management to urban planning. It provides a detailed visual context that enhances the understanding and interpretation of geospatial data.

Effortless Uploading to Mapillary Platform
Uploading the processed data to Mapillary is designed to be a hassle-free process. The structured data, once uploaded, is ready to be analyzed and integrated with existing maps on the Mapillary platform.
Working with Data on Mapillary
Automatic Extraction of Object Classes and Full Segmentation of Imagery
Mapillary’s sophisticated algorithms automatically identify and extract up to 42 objects as point features from the uploaded imagery. The platform also segments the imagery into various categories of assets, providing a detailed breakdown for more in-depth analysis.
In January 2019, Mapillary broadened its horizon by introducing the capability to identify and position 42 new point features on maps from street-level imagery, a significant leap from its initial focus on traffic sign recognition. This advancement came as a boon to cities and mapping entities striving to keep their maps updated. The simplicity of the process is noteworthy; individuals can use basic cameras to capture imagery, which is then analyzed by Mapillary’s sophisticated computer vision technology to identify and map a myriad of objects such as utility poles, streetlights, and manholes.
Initially, Mapillary had honed its algorithms to detect around 1,500 types of traffic signs.
However, with this new addition, the platform’s recognition capabilities extended across diverse categories like pedestrian mobility, cycling, transportation, public works, and road maintenance, significantly enriching the data available for geospatial analysis. Although initially these features were in beta and available through a subscription, the object and traffic sign identification capabilities have since transitioned into the public domain, making them accessible to a broader audience. Mapillary continues its journey with plans to extend traffic sign recognition to more countries and incorporate optical character recognition for textual signs, embodying a relentless pursuit to make geographical data more detailed, current, and universally understandable.

Object Detection by Mapillary
Mapillary’s computer vision technology utilizes a method known as semantic segmentation to autonomously identify various objects depicted in images, such as buildings, cars, pedestrians, and bicycle racks. Each image is tagged with geocoordinates, enabling the visualization of object detections on a map. This feature allows for filtering images based on the presence of specific objects. The map at this juncture reflects the positions of images where certain objects are visible, aiding in the identification and categorization of objects found within the images.
Though the map visualizations represent where certain objects are detected, it’s a step away from map features which take it further by triangulating the real-world location of an object detected in several images, determining its actual location, and placing it on the map as a map feature. To access and utilize these automatically extracted object detections, one needs to query map data using the Mapillary API. These capabilities are available for exploration on the Mapillary web app, making it a powerful tool for geospatial analysis and urban planning endeavors.
Below is the list of 65 object classes detected by Mapillary (in addition to traffic signs and point features):
