What is the development history of remote sensing science and land resources remote sensing?

Remote sensing is a new technology developed on the basis of aerial photography, which was developed in the early 1960s. Started for aerial remote sensing, since 1972, the United States launched the first land satellite, marking the beginning of the era of space remote sensing. After decades of rapid development, remote sensing technology has been widely used in resources and environment, hydrology, meteorology, geology and geography and other fields, and has become a practical and advanced space exploration technology.

germination period

The ground remote sensing stage was not recorded (1608-1838);

1608 Hans liporsay made the world's first telescope.

1609 Galileo made a scientific telescope with a magnification of three times and observed the moon for the first time.

1794 the first balloon reconnaissance pioneered the observation of long-distance targets, but telescope observation could not record the observed things in the form of images.

Recorded ground remote sensing stage (1839- 1857):

1839, Daguerre released the photos he took with Nipps, and successfully recorded them on film for the first time.

1849, Aime Laussedat, a Frenchman, made a photogrammetry scheme, which marked the development of ground remote sensing to a purposeful and recorded stage.

Initial development

Remote sensing stage of aerial photography (1858- 1956)

1858, aerial view of Paris, France, taken with tethered balloons.

The Invention of Aircraft 1903

1909 The first aerial photograph

During World War I (1914-1918):

Form an independent subject system of aerial photogrammetry

During World War II (193 1- 1945):

Color photography, infrared photography, radar technology, multispectral photography, scanning technology, vehicles and mapping equipment.

Modern remote sensing

1957: The former Soviet Union launched the first artificial earth satellite.

1960s: The United States launched meteorological satellites such as TIROS, ATS and ESSA and manned spacecraft.

1972: the earth resources technology satellite ERTS- 1 (later renamed Landsat- 1) was launched, which has an MSS sensor with a resolution of 79 meters.

1982 Landsat-4 launch, equipped with TM sensor, the resolution is improved to 30 meters.

1986 France launched SPOT- 1, equipped with PAN and XS remote sensors, with a resolution of 10 meter.

1999, the United States introduced IKNOS, and the spatial resolution was improved to 1 meter.

Remote sensing in China

In the 1950 s, a professional flying team was established to carry out aerial photography and application.

1970 On April 24th, the first artificial earth satellite was launched.

1975165438+1October 26th, the satellite can be recovered and the satellite photos can be obtained.

It was unprecedentedly active in the 1980s, and remote sensing was included in the national key scientific and technological projects during the Sixth Five-Year Plan.

1 On September 7th, 988, China launched the first meteorological satellite "Fengyun1".

1999 10 China successfully launched a resource satellite in June 14, and then entered a period of rapid development-satellite, manned space flight, lunar exploration project, etc.
