Maintaining Danish Highways Driving operational efficiencies

Author: Simon Hall

A national road network is one of the most important pieces of infrastructure any country will ever built and maintain. Ensuring that these public highways are kept to the highest possible standard results in a dramatic increase in public safety, however it is possible for some roads are not kept to the standards required.

超过11000公里的双车道公路,阿龙g with several thousand more smaller roads, the Danish Road Directorate (Vejdirektoratet) contracted Getmapping after a tendering process to survey the road state network. High density terrestrial point cloud data and matching high resolution panoramic imagery would be collected using the state-of-the-artLeica Pegasus: Two Mobile Mapping Ultimateequipment.

Getmapping PLC is a leading global provider of geospatial data and survey solutions. They have over 20 years’ experience in the capture and delivery of high-resolution aerial imagery, LiDAR, digital mapping and web-based services across Europe and Africa. Their goal is to enable the timely and cost-effective delivery of geospatial data, creating digital replicas of the world. Getmapping collects, transforms, stores and delivers scalable geospatial data, mapping and modelling solutions to enable better decision making. By creating true digital replicas of the environment, their aim to empower their customers and partners to create solutions to the challenges facing their business and the planet.

Vejdirektoratet或丹麦道路局负责丹麦国家道路网络，该网络由高速公路，几条主要道路和许多桥梁组成。他们为每天使用丹麦州道路的许多道路使用者创造连贯性。他们通过开发，计划和建造丹麦的基础设施并将国家束缚在一起来实现这一目标。它需要平衡移动性，环境和道路安全的解决方案。

About the Project

Despite having some of the safest road in Europe with only 30 deaths per million inhabitants in 2020 , the goal of Vejdirektoratet was to scan the 11,000 km of road networks across the country using the Leica Pegasus: Two Mobile Mapping Ultimate solution, enabling them to collect high density terrestrial point cloud data and matching high resolution panoramic imagery.

“This is an exciting project for Getmapping. Denmark is a new market for us and expands our presence as the leading supplier of aerial and mobile mapping services across North-West Europe.”
Gavin Sullivan | Deputy Head of Europe – Getmapping, United Kingdom

Within 6 months of the contract award, Getmapping were scheduled to have delivered a full dataset of 3D laser point clouds and 360-degree photos to the Danish Road Directorate, covering all state roads and their immediate surroundings.

Challenges

Several challenges faced the Getmapping team in the build up to the project. The scale of the project was one of the largest Mobile Mapping projects ever undertaken by Getmapping, with more than 11,000 line kilometers to cover. The extensive data processing and classification requirements, including image anonymisation, 4 classes of LiDAR classification, and the timescales, requred Getmapping to deliver of the fully processed data set, including data capture, in less than 6 months.

“ Covid19和英国脱欧在GetMapping方面已经是'新常态'，并且被包括在我们所有的活动中。该项目的最大挑战是在如此短的时间内捕获，处理和分类如此大量数据的紧迫截止日期：从未做过的事情！通过确定每个任务的持续时间和依赖性并将足够的团队管理专门管理为每个任务，从而使该项目成为可能。透明
Alexandre Alves | European Operations Manager – Getmapping, United Kingdom

Despite the challenges – the scale, extensive data processing and short execution period, Getmapping delivered the clients expectations:

• 高效的数据捕获，这意味着只需要捕获一次数据才能满足项目规格
• Hundreds of line kilometres captured per day ensured all mapping was completed within 3 months of the project start date
• The mobile mapping data, including classifications was processed and delivered in phases, providing usable and relevant information for immediate consumption and analysis
• The full data set was delivered within the required 6 month deadline

Mobile mapping solution

With theLeica Pegasus:Two Ultimatemobile mapping solution, Getmapping were able to use the laser scanners in combination with GNSS receivers, IMU and a DMI, acquiring accurate and precise spatial data with cameras mounted on their vehicle.

创新的移动传感器平台捕获了所需的点云和成像数据。多传感器方法允许GetMapping通过在一次通过中收集更多数据，减少在现场的时间来增加ROI，并且
generate higher results with the same resources. The reality capture solution is completely vehicle-independent, making it a competent solution across multiple applications without limiting users to road and rail.

只需捕获数据就可以捕获数据，一旦超过了点密度和预期数据准确性，确保员工安全并减少在现场的时间。飞马：两个被捕获

对未来的看法

The Leica Pegasus:Two Ultimate was the best option for the project. Using this mobile mapping system, it took less time and was more cost effective than any other surveying method to achieve this level of detail and accuracy. The data also drove operational efficiencies, enabling the Vejdirektoratet employees to carry out visual inspections and measurements from the office, mitigating the health and safety risks of site visits. The new data will also allow them to develop completely new methods and applications in a wide range of areas.

“Getmapping have a strong focus on collaboration. For projects like this, the benefits of this consultative approach went beyond the provision of best of breed technology, to how we collectively provided our customer with high quality business insights, effectively and efficiently.”
Helen Wattie | European Sales Manager – Getmapping, United Kingdom

Getmapping are now actively marketing for other bespoke survey opportunities using the Pegasus:Two, and this project showcases the extent of the surveying that they can provide.

在过去的12个月中，他们与迅速越来越多的客户合作，这些客户正在寻求更快，更安全，具有成本效益的替代替代传统地形调查技术，以及他们的移动映射解决方案正在以各种新的创新方式使用，包括公路规划，资产管理，监视变更，停车应用，3D建模和人工智能。
