定制今天的城市管理

The world is changing and becoming increasingly complex. Cities face great challenges as most of world's population lives in urban areas, and city management is becoming more demanding. In light of new challenges, municipalities and local governments are looking for efficient management solutions to provide detailed information, data and analysis for effective city management.

Envirosense匈牙利有限公司. is a remote sensing specialist that emphasises on the process of aerial sensed inputs. Understanding city management needs, the firm offers varied advanced products for surveys that are impossible to be conducted by traditional on-field surveys or need large resource inputs. Focusing on aerial hyperspectral imagery, airborne laser scanning (LiDAR), unmanned aerial vehicle (UAV) applications and aerial digital imagery, Envirosense Hungary Ltd provides personalised solutions that fulfil the customer needs.

The company’s goal is to provide local governments with smart products adapted to their needs. Most local governments don’t have an in-house team of remote sensing experts or geographic information system (GIS) experts who can process data or develop methods to tackle specific challenges.

“In many cases, the problems exist but the link with airborne technology is not made or the technical solution has not been developed yet. We aim to be innovative; we develop user-ready products and solutions and deliver them to local governments,”Envirosense匈牙利有限公司LIDAR部门经理Peter Enyedi说。

Using the latest LiDAR technology

“Our products have to achieve high accuracy, high resolution, and conform to the latest standards in the photogrammetry and LiDAR market,”Envirosense Hungary Ltd.摄影测量部经理Gregory Lucas说。

Envirosense使用Leica GeoSystems ALS技术与LiCA RCD30中格式RGBN摄像机相结合，用于空中调查，而Leica viva CS15 CS15现场控制器用于接地调查。基于这项技术，Envirosense通过定制解决方案响应客户需求。

“Some of the products consider trees and vegetation so a four-channel camera was a need. Radiometry and light sampling is important for the segmentation issues. We are also working intensively with LiDAR-hyperspectral data fusion. The choice of a photogrammetry and LiDAR system is fundamental for our projects,”埃尼迪说。

“我们已经使用了Leica Geosystems空降双传感器和相机，用于自2012年以来需要激光或图像的所有空降任务，”埃尼迪说。“It’s the high quality, cost这些年来，LIDAR系统的效率和性能使我们成为了忠实的Leica Geosystems客户。”

Introducing airborne technology

Envirosense在各种应用中使用地理系统的传感器来有效地支持城市管理中的地方政府，例如：

1. Terrain models for water authorities
2. Flood modelling
3. 植被图
4. Land use classification
5. Agricultural applications
6. 林业(invasive species mapping, biomass estimation)
7. Nature conservation
8. 考古学
9. Urban planning
10. Vinery应用程序

EnviroSense不仅仅生成基本数据集，还可以提取信息并将其提供给其客户。该公司根据该团队根据LIDAR点云和空中多光谱图像对城市物体和表面类型进行分类，以根据该团队为城市物体和表面类型进行分类，在2018年的2018年空降用户组会议上作了演讲。使用基于对象的特征提取方法，可以从城市表面类型到树木的一系列产品生成一系列产品。bob综合app下载这提供了决策和进一步分析的基础。

此外，它为详细和多样化的数据库维护开辟了道路，从而允许清单和外部任务。数据可以与无人机平台收集的空中高光谱数据，卫星数据和数据集成。

数据是用于详细的内装的g modelling and structural change detection. Cities can check whether construction permits were issued, and insurance companies can assess values of the houses.

There is a wide use of the data for forestry mapping management. The trees can be identified, and the tree health can be detected to avoid the spread of diseases. Damages from falling trees are the city’s responsibility. This technology allows local governments to ensure that all the trees are in good condition.

In addition, roof objects, such as climate units on houses, can be detected to define insurance values of the house. Solar potential of the city can also be identified; LiDAR technology helps local governments define the areas that are best for installation of units and calculate how much of the power can be economised.

“我们提取和映射的大量对象反映了空中系统获取的数据的质量以及我们用于映射和分类方法的进步，”埃尼迪说。

Among the features Envirosense can extract are:

1. Roof types
2. 烟囱
3. The type of surface cover (streets)
4. Road signs
5. 太阳能电池板元素
6. Potential places for placing solar panel elements
7. Objects on the ground
8. 公墓的特征
9. Trees and vegetation
10. Surface water networks
11. Power lines

Making it personal

Envirosense's strategy is to develop custom-made products for clients who are not experts in remote sensing and GIS fields, but their needs require aerial remote sensing technology.

“It is the direction where we see the biggest potential for development; the opportunities are unlimited,”埃尼迪说。

Envirosense recently created开放式街景, a new solution for its orthoimagery product line. The solution allows local governments to identify ground-located objects, useful for any organisation’s inventory tasks. Envirosense uses the same airborne survey equipment, but the planning and processing is adapted to the project’s specific needs.

Looking ahead

LiDAR solutions and imagery technology in combination offer incredible and flexible capacities for mapping and classification.

“我们希望将来将我们的产品用于城市管理目的。”said Lucas.“我们将继续使用地理系统的机载解决方案和相机，因为它们为这类项目提供了最大的效率。”
