Say goodbye to why Sichuan in the "No Tu Zone" era does a basic surveying and mapping database?

In 2022, Sichuan realized a 1: 10,000 test drawing in the whole region to bid farewell to the era of "no picture zone". At the same time, the 1: 10,000 basic geographical information database covered the province was built to achieve the province's 1: 10,000 map regional basic geographical information resource coverage.

What is basic surveying and mapping? During the National Layout Awareness Publicity Week, the sixth terrain surveying team of the Ministry of Natural Resources will give you a popular science.

Basic surveying and mapping refers to the establishment of a national unified surveying and mapping system and surveying and mapping system, conduct basic aviation photography, obtain remote sensing data for basic geographical information, and update the national basic ratio map, image map and digital products, establish and update the basic geographical information system, and update the basic geographical information system. Public welfare and basic.

With the acceleration of the globalization process and the rapid development of regional coordination, the demand for basic surveying and mapping results in various government departments, enterprises and institutions, and the public, especially with the development of economic and social development, as well as cloud computing, the Internet of Things, and the Internet of Things, and Big data, information and communication technology (ICT) and artificial intelligence (AI) and other related technologies such as the deep integration of surveying and mapping have put forward higher requirements for basic surveying and mapping results.

Traditional basic surveying and mapping are changing to a new basic surveying and mapping system required for "global coverage, sea and land, linkage, linkage, and open sharing on demand, open sharing".

In order to further strengthen the basic surveying and mapping work, improve the level of guarantee service, and better serve the province's high -quality development in order to further strengthen the basic surveying and mapping work. In recent years, the following basic surveying and mapping projects have been established.

Why do you need to carry out 1: 10,000 map regional map engineering? As one of the few provinces that have not achieved 1: 10,000 basic geographical information data, Sichuan, as a large economic province and surveying and mapping provinces. As of the end of the "Twelfth Five -Year Plan", the province's 1: 10,000 basic geographical information data coverage rate is only It is 66.5%.

In order to meet the demand for basic geographical information resources such as ecological civilization construction, disaster prevention and mitigation, new urbanization construction, and precision poverty alleviation under the new situation, our province needs to "replenish debts" as soon as possible to achieve 1: 10,000 basic geographical information Global coverage of data.

Sichuan Province 1: 10,000 diagram area measurement project mainly completes the 1: 10,000 map area of ​​Sichuan Province in 3 years, 6063 (about 163,000 square kilometers) digital positive shooting image diagram (DOM) production and digital line strokes Figure (DLG) production, digital high model (DEM) production and topographic map editing, and at the same time built 1: 10,000 basic geographical information database covering the province, to achieve the province's 1: 10,000 map regional basic geographical information resource coverage.

The results of engineering construction can provide basic surveying and mapping for ecological civilization construction, major engineering planning and construction, operation and maintenance, people's livelihood protection, disaster prevention and minus and minus and minus mitigation.
