定制对于今天的城市法力gement

世界正在变化并变得越来越复杂。随着世界大多数人口居住在城市地区，城市面临巨大的挑战，城市管理越来越苛刻。鉴于新的挑战，市政当局和地方政府正在寻找有效的管理解决方案，以提供有效城市管理的详细信息，数据和分析。

Envirosense Hungary Ltd。是一位遥感专家，强调空中感知的输入过程。了解城市管理需求，该公司为传统的现场调查或需要大量资源投入提供各种调查的高级产品。bob综合app下载Envirosense Hungary Ltd专注于空中光谱图像，空降激光扫描（LIDAR），无人机应用（UAV）应用和空中数字图像，提供了满足客户需求的个性化解决方案。

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,”said Peter Enyedi, manager of the LiDAR division at Envirosense Hungary Ltd.

使用最新的激光雷达技术

“我们的产bob综合app下载品必须达到高精度，高分辨率，并符合摄影测量和激光雷达市场的最新标准，”said Gregory Lucas, manager of the photogrammetry division at Envirosense Hungary Ltd.

Envirosense uses Leica Geosystems ALS technology combined with the Leica RCD30 medium format RGBN camera for the aerial surveys and the Leica Viva CS15 field controller for ground surveys. Based on this technology, Envirosense responds to customer needs with custom-made solutions.

“有些产品认为树木和植被，bob综合app下载因此需要四通道相机。辐射仪和光抽样对于分割问题很重要。我们还与LiDAR-Hypspectral Data Fusion进行了大量合作。摄影测量和激光雷达系统的选择对于我们的项目至关重要，”said Enyedi.

“We have used the Leica Geosystems airborne dual sensor and camera for all the airborne missions requiring LiDAR or imagery since 2012,”said Enyedi.“这是高质量，成本efficiency and performance of the LiDAR system that make us a committed Leica Geosystems customer all these years.”

引入机载技术

Envirosense uses Geosystems’ sensors in a variety of applications to effectively support local governments in city management, such as:

1. 水当局的地形模型
2. Flood modelling
3. Vegetation mapping
4. 土地使用分类
5. 农业图l applications
6. 林业（入侵物种图，生物量估计）
7. 自然保护
8. Archaeology
9. 城市规划
10. Vinery application

Instead of just generating basic datasets, Envirosense extracts the information and offers it to its clients.The company gave a presentation during the 2018 Airborne User Group Meeting in Lisbon, Portugal, based on a research the team did to classify urban objects and surface types based on LiDAR point cloud and aerial multi- or hyperspectral imagery. With object-based feature extraction methods, a series of products can be generated from urban surface types to tree cadastre. This offers the basis of decision making and further analysis.

In addition, it opens the way to detailed and varied database-maintenance, allowing inventories and cadastres tasks. The data can be integrated with aerial hyperspectral data, satellite data and data collected by UAV platforms.

数据用于详细的建筑建模和结构变化检测。城市可以检查是否已颁发施工许可证，保险公司可以评估房屋的价值。

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.

“The multitude of objects we extract and map reflects the quality of the data acquired by the aerial system and the advancement of our methods for mapping and classification,”said Enyedi.

Envirosense可以提取的功能包括：

1. 屋顶类型
2. Chimneys
3. 表面盖的类型（街道）
4. 路标
5. Solar panel elements
6. Potential places for placing solar panel elements
7. 地面上的物体
8. Features in cemetery
9. Trees and vegetation
10. 地表水网络
11. 电力线路

Making it personal

Envirosense的策略是为不是遥感和GIS领域专家的客户开发定制产品，但他们的需求需要空中遥bob综合app下载感技术。

“这是我们看到开发潜力最大的方向；机会是无限的，”said Enyedi.

Envirosense最近创建了Open Street View, 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.

展望未来

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.“We will continue working with Geosystems' airborne solutions and cameras as they offer the maximum efficiency for this type of projects.”
