How to make a geographical sand table

1 production technology and production process

Carving, coloring and post-treatment.

Common elevation data formats: DEM, STL, ASC, etc.

1. What is a real satellite sand table?

Satellite real-life sand table refers to the world's leading high-precision real-life sand table making technology, which seamlessly connects with satellite remote sensing data (satellite image map, topographic map and real-life map), collects real three-dimensional geographic information data, and displays topography and landforms in the same scale with three-dimensional ink painting technology to simulate information such as mountains, water bodies, roads and vegetation. DEM data accuracy is 30M. The accuracy of image data is 0.5M, and the accuracy of model matching is1mm.

2. Can only satellite data make a real sand table?

In addition to satellite data, we can also make small-scale, high-precision real-life sand table through oblique shooting and aerial photography.

3. The characteristics of real sand table.

1. The world's leading high-precision real-life sand table making technology;

4. Various labels and lines can be customized to meet the differentiated needs of customers;

5. Suitable for making large-area, large-format sand table models with complex information.

4. What are the application fields of real sand table?

1. Land and resources mapping: comprehensive improvement planning of land and resources, land mapping, planned land use and land use? Present situation investigation and land dynamic change monitoring, land cover information and analysis, land development and management;

2. Urban planning and construction: urban (township) planning and construction and change monitoring, urban expansion monitoring and regional development;

3. Traffic construction: highway planning and management, waterway, waterway and railway line planning and display;

4. Reservoir distribution sand table: Quickly make various types of high-precision reservoir distribution sand tables, covering any country in the world. Need to add contour lines, commanding heights, water systems, roads, etc. ;

5. Exhibition hall: In museums (archaeological cultural relics research), science and technology museums, exhibition halls, exhibition halls and enterprise halls, high-simulation sand table models of various historical scenes, restoration of ancient cultural relics and emerging scientific and technological products of nebula galaxies are designed and produced according to different needs;

6. Educational model: true-color three-dimensional model of topography sand table and common landforms in the world and China: geography teaching equipment such as Danxia, karst, coast and seabed;

7. Decorate sand table: enhance the layering of the office, and add relevant elements according to users' professional interests, such as road traffic, topography, vegetation coverage, mineral distribution, etc. It can better reflect the professionalism and cultural atmosphere of users.
