What is Surveying and Mapping Remote Sensing?

Surveying and mapping remote sensing is the act of using remote sensing technology to calculate on the computer to achieve the purpose of surveying and mapping.

Remote sensing refers to non-contact and long-distance detection technology. Generally, it refers to the detection of electromagnetic radiation and reflection characteristics of objects by sensors/remote sensors. Remote sensing is to detect the target object by remote sensors and other instruments sensitive to electromagnetic waves under the condition of being far away from the target and not touching the target object.

It is a science and technology to obtain reflected, radiated or scattered electromagnetic wave information (such as electric field, magnetic field, electromagnetic wave, seismic wave, etc.). ) and extraction, judgment, processing, analysis and application.

Extended data:

Remote sensing technology has been widely used in agriculture, forestry, geology, ocean, meteorology, hydrology, military affairs, environmental protection and other fields. In the next decade, remote sensing technology is expected to enter a new stage, which can provide various earth observation data quickly and timely.

The spatial resolution, spectral resolution and temporal resolution of remote sensing images will be greatly improved. With the development of space technology, especially the development and mutual penetration of geographic information system and global positioning system technology, its application field will be more and more extensive.

The application of remote sensing information is the ultimate goal of remote sensing, which should be carried out according to the needs of professional objectives in order to obtain better social and economic benefits.
