Aviation remote sensing surveying and mapping

Mar 22, 2022

Is obtained by the industry news: the Chinese national geographic information bureau of surveying and mapping said 2018 will accelerate the construction of aerospace Remote sensing mapping, through high score 7 satellite launch preparation, promote resource 03 star project no. 3, 4 star, the construction of domestic satellite receiving station and overseas processing system, promote new platforms such as drones, and airborne laser radar is a new application of sensor, gradually formed multi-resolution, multi-type, multi-sensor, all-weather comprehensive efficient aerospace Remote sensing mapping ability. This marks the arrival of the era of aviation Remote sensing surveying and mapping, and China will accelerate the construction of aviation Remote sensing surveying and mapping.

According to the national conference on surveying and mapping and geographic information, China's ability to independently obtain geospatial information has been greatly improved since the successful dual-star networking and operational operation of China's domestic civil high-resolution stereo mapping satellite resource no. 01 and 02. The binary star effectively imaged and obtained the original data to break through 10,000 orbits, and the image data reached 2.65 million scenes. China's land and sea areas have effectively covered 11.41 million square kilometers, covering more than 99 percent of China's land area. Effective coverage of 93.5 million square kilometers worldwide. Relying on the resources no.3 as the core of domestic surveying and mapping satellite, the national 1:50000 scale topographic map to achieve the annual update total factor, national basic geographical conditions and situation to achieve normalized monitoring, part of the key areas to realize the multiple cycles repeat monitoring within the year, "world map" platform for domestic satellite imagery annual update rate above 90%. Up to now, it has provided more than 2,000 users in land, agriculture, water conservancy, transportation, environmental protection and other social fields with 570,000 views, covering an area of more than 300 million square kilometers of satellite imaging products and services, realizing the independent guarantee of satellite surveying and mapping geographic information services, and achieving good social and economic benefits.

At the same time, the United Kingdom, Australia, Germany, Brazil, Norway, Mexico and other countries and regions have used the data of the experiment to carry out ecological and environmental monitoring and land resources survey, which has played an active role in scientific and technological cooperation and international exchanges.

The director of the state administration of surveying, mapping and geographic information pointed out at the meeting that Remote sensing surveying and mapping in aviation and aerospace is an important support for the data source for the development of the cause and must rely on scientific and technological progress to build a unique business system.

First, we need to speed up capacity building.

Actively promote the national civil space infrastructure for medium and long-term development planning and implementation of Remote sensing satellite constellation, prepared to score 7 launch, promote resource 03 star project no. 3, 4 star, construction of domestic satellite receiving station and overseas processing system, promote new platforms such as drones, and airborne laser radar, the application of new type sensor gradually formed multi-resolution, multi-type, multi-sensor, all-weather comprehensive and efficient aerospace Remote sensing mapping ability.

Second, focus on data integration.

Looking at both home and abroad market, focus on the military and civilian depth fusion, focus on the marketization of public welfare safeguard and service requirements, to plan as a whole ", "outside the army, the people, business and earth observation data resources, promote aerospace Remote sensing survey and mapping data points to build sharing, resource integration, management as a whole, more efforts to buying services from domestic commercial satellite Remote sensing.

Third, we will work hard to expand its application

We will study the model of active service, intelligent service and one-stop service, establish a Remote sensing data policy suitable for China's national conditions, build a value-added service platform for aerospace Remote sensing surveying and mapping, promote the commercial application of Remote sensing data and international services, and promote the industrial application of the beidou navigation satellite system and its comprehensive integration with surveying and mapping satellites.

The personage inside course of study, according to the national civil space infrastructure for medium and long-term development plan (2015-2025), "demand for surveying and mapping in the application, the resource subsequent star, no. 3 high business seven star, interference radar, and the principle of gravity satellite 7 of surveying and mapping satellite into planning, mainly used in 1:50000, 1:1 and larger scale map mapping and updating, resources survey, urban and rural planning, environmental protection and disaster warning and rescue, etc.
