We choose digital preservation techniques to protect canal and canal-side buliding.

Rebuild

Protect

prevent

we can't stop the history from happening, there are too many factors affecting the preservation of the canal, so we may need to focus on how to rebuild the traditional building.

This way, we can avoid demolishing important parts of our cultural heritage.

we can disguise as a foreign man and went record the details and sent it to the modern world and build a model for the ancient great canal .

this way we can also get information of more details in order to know more about the ancient building and the traditional or regional design.

Remote sensing is the process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance,We can use satellites and CCTV to monitor the changes of the grand canal in a very swift way, by doing this, we can see the change of the canal clearly and thoroughly, we can also use satellites to collect data and build a 3d model for renovating the canal without any bad impact. remote sensing technology can help get all the data that is needed ,the other ways can't get the data, without databases, all the other ways,is totally useless.

What is it?

-Use 3D scanning to preserve the model, if the building is destroyed, then it can be built again

# data[].attributes.body
It can save the 3D model of the buildings, so we can rebuild these in the future if they get demolished

# data[].attributes.body
Why we chose this?

-Because it allows u to see the structures of the old buildings and allows experts to renovate it

-Most importantly, focus on structures (since ancient buildings have weak support)

-Knows where and what to repair detailedly and clearly

Our group chooses Smart Water Management System. Our ancestors were very successful at managing water, so they were more comfortable using this management system. It is easier for them to protect the building.And this technology helps us address the root cause of the problem.So we don’t have to spend a lot of money and time on fixing the building over and over again.Not only can it protect buildings, but it can also prevent some natural disasters at the same time.We can build some dams and some waterwheels to help generate electricity.According to the rise and fall of the water level, the valves are opened and closed regularly to ensure that the dangerous water level will not be exceeded, thereby flooding surrounding buildings and residential areas.

Scanning the structure of the monument and duplicate a model utilizing digital technologies. Resulting a copy of them which can be a reference for renovation.

Introduction:

A Geographic Information System (GIS) is a computer system that analyzes and displays geographically referenced information.

GIS in The Grand Canal:

If GIS could be used in The Grand Canal, We can monitor the water quality and level rise of the Grand Canal in real time.

And it can be modeled to predict risk, so we can come up with solutions in advance, before the unexpected happens.

Successful examples:

In China, there is a successful example in the hangjing canal, and it has attained a good achievement.

以2002年SPOT5影像和2022年的GF1影像为基准，利用随机森林方法对京杭大运河扬州段沿岸1 km范围进行土地利用分类，基于土地利用转换矩阵、土地利用动态度模型和重心迁移模型进行分类后比较。结果表明：20 a间，研究区耕地、林地、水域面积减少，草地、建设用地、未利用地面积增加。耕地为转出面积最多的土地类型，主要转出为建设用地。研究区的综合土地利用动态度为0.63%，整体土地利用类型数量变化相对平稳，未利用地和建设用地的单一土地利用动态度分别为4.61%和4.10%，数量变化相对剧烈。耕地和林地重心向北迁移，建设用地和水域重心向南迁移，耕地重心迁移距离最大（6.38 km）。

How?

-Use it to scan all the historical buildings

-Preserve the building in 3D files

• Erosion risk assessment and monitoring: GIS integrates data from topography, land use, and rainfall to calculate soil erosion rates.(through models (e.g., USLE or RUSLE) and generating erosion risk maps.)
• Watershed management and planning: GIS aids in forming rational land use plans to reduce erosion.
• Erosion process simulation and prediction: GIS can be combined with hydrological models to simulate river erosion processes and predict future trends.

1. Real-time Monitoring and Water Quality Assessment:

GIS can be utilized to monitor the water quality and water level of the Grand Canal in real-time. By regularly collecting coordinates of mobile monitoring targets from operational systems or GIS and displaying them on maps, it's possible to effectively monitor real-time changes in water quality and water levels. This is crucial for preventing and managing potential environmental issues.

2. Risk Modeling and Prediction:

GIS can be employed for modeling and predicting risks associated with the Grand Canal, such as floods or pollution leaks. By simulating different risk scenarios, preemptive solutions can be developed to address unexpected events.

3. Successful Examples:

In China, there is a successful example of GIS application in the Hangjing Canal, which has achieved good results. Researchers have established a five-index model that connects heritage sites and historical events, revealing the degree of interrelation between them. Additionally, teams have comprehensively organized cultural heritage sites along the canal through literature reviews and field surveys, providing a solid data source for further studies.

4. Cultural Heritage Protection:

GIS technology is also used for the protection of cultural heritage along the Grand Canal. Spatial analysis methods in GIS, such as kernel density analysis, nearest neighbor analysis, centroid analysis, and standard deviation ellipse methods, have been used to study the distribution of 104 cultural heritage sites along the Suzhou section of the canal across six historical periods and discuss the influencing factors of distribution evolution.

5. Intangible Cultural Heritage (ICH) Protection and Utilization:

GIS technology reveals the non-uniform distribution of different types of ICH resources along the Grand Canal and proposes ICH regeneration and utilization plans based on local factors. This includes strengthening regional cooperation, developing tourism projects to showcase ICH resources near the canal, and establishing digital protection systems for ICH.

In summary, the application of GIS technology in the Grand Canal is multifaceted, including real-time monitoring, risk prediction, cultural heritage protection, and the protection and utilization of intangible cultural heritage. These applications have achieved certain successes and effects.
