1. Collecting data: terrain data needs to be collected, which can include information such as the height, slope and direction of the terrain. These data can be obtained by topographic survey or remote sensing technology.
2. Data processing: After data collection, it needs to be processed. This includes cleaning, sorting, and transforming data in order to convert it into a model.
3. Making terrain prototype: Making terrain prototype according to the processed data. This can be done by using clay, gypsum, plasticine and other materials. Shape the terrain according to the data and pay attention to the ups and downs of the terrain.
4. Making contour lines: Draw contour lines on the prototype surface according to the data. The distance and thickness of contour lines can be adjusted as needed to show the details and features of the terrain.
5. Drying and shaping: after the outline is drawn, dry the prototype. After drying, materials such as paint and adhesive can be used to shape the model to improve its stability and durability.
6. Annotation and explanation: Annotate and explain the model. This includes marking topographic features, contour values and other information so that readers can understand the meaning and usage of the model.
Application of contour topographic map model;
1. Education and scientific research: Contour topographic map model can be used in the field of education and scientific research, providing students and researchers with intuitive terrain and geomorphology display. In the teaching of geography, geology, environmental science and other disciplines, contour topographic map model can help students better understand the formation and evolution of terrain.
2. Decision support: Contour topographic map model can provide intuitive topographic data and landform display for decision makers to help them make more reasonable decisions. For example, in urban planning, land resources utilization, water resources management and other fields, contour topographic map model can provide important reference.
3. Disaster prevention: The contour topographic map model can be used in the field of disaster prevention, such as the prevention and response to natural disasters such as earthquakes, mudslides and landslides. Through the contour topographic map model, we can better understand the characteristics and changes of terrain, predict and evaluate the risks and impacts of natural disasters, and provide important reference for disaster prevention and control.
4. Tourism planning: Contour topographic map model can be used in the field of tourism planning, providing intuitive landscape display and reference for tourism developers. In the development of tourism resources such as mountainous areas and hilly areas, contour topographic map model can help developers better understand the characteristics and changes of terrain, and provide important reference for tourism route planning and tourist attractions development.
