With the continuous development of science and technology, the application of remote sensing technology has promoted the research and development and popularization of surveying and mapping technology. The current surveying and mapping work mainly includes environmental monitoring, geological exploration and resource mapping. The use of remote sensing technology can detect a large area of land, and real-time detection of geological conditions. The high precision and reliability of this technology play an important supporting role in the further development of modern surveying and mapping technology. Based on information technology, remote sensing technology provides great convenience for the detection and measurement of various resources, environment and land surface dynamic changes.

In geological engineering, geographic detection technology has been widely used. The development of mineral exploration and biological science and technology has higher requirements for geographic detection technology, geographical staff must constantly update detection techniques and methods. This paper is based on the analysis of surveying and mapping remote sensing technology, in order to improve the efficiency of geographic detection system.

1.Surveying and mapping remote sensing technology

In modern surveying and mapping technology, remote sensing technology is a method of long-distance detection through some necessary sensors, and finally deeply analyze the attributes of the target object according to the detection data. Remote sensing technology has always been highly practical from the initial aerial photography to modern geological surveying and mapping. Modern remote sensing technology mainly carries out high-altitude shooting through satellites, and there is no need for personnel on-the-spot inspection when exploring space, which saves the related costs of personnel and equipment. For geographical detection, the use of satellite remote sensing can provide convenience for measurement, and can improve the accuracy and reliability of measurement. Compared with the traditional surveying and mapping technology, its advantages are reflected in the following three aspects:

• Wide coverage. Surveying and mapping remote sensing technology can comprehensively analyze the situation in a certain area, and finally obtain more comprehensive data.
• It has omni-directional, multi-domain and dynamic real-time detection function. During the survey process, the GPS is used as the support, and after the spatial navigation and positioning, the geographical detection area can be dynamically detected in all weather.
• There are few intervention factors. In the measurement, the defects of human measurement are effectively avoided, the measurement accuracy is improved, the error is avoided, and is not affected by time and space factors.

2.Specific application of surveying and mapping remote sensing technology

The application of surveying and mapping remote sensing technology in geographical inspection is mainly reflected in two aspects:

• Obtain relevant geographic data. The application of surveying and mapping remote sensing technology in geographical inspection has effectively promoted the continuous progress and development of geography in our country. The use of remote sensing technology can obtain the image of the earth surface, effectively combined with camera technology, improve the resolution of satellite photography, and provide an important guarantee for map making with clear and intuitive satellite images. Because the map information obtained by remote sensing technology can truly reflect the actual situation of buildings, and in the process of shooting, pop can be used to obtain more geographic information, which further increases the exploration of resources in our country, therefore, the application of remote sensing technology of surveying and mapping in geographical inspection plays a very important role in promoting the utilization of water conservancy, mineral resources and land resources in our country.
• The specific application of mapping and remote sensing technology in the exploration of geological disasters. When using satellite remote sensing technology, without the limitation of time and space, geographic information can be collected at high altitude and applied to the exploration of geological disasters, which provides great convenience for geographical detection. When a geological disaster occurs in a certain area, in order to quickly carry out the rescue work, it is necessary to roughly understand the geological disaster situation in the area and check the latest map information. After the application of surveying and mapping remote sensing technology, we can not only quickly obtain the relevant map information, but also clearly understand the geological disasters in the area, which is conducive to the smooth development of the rescue work. In addition, as the surveying and mapping remote sensing technology is an important part of the geographic information system, the data information and pictures obtained through the survey can facilitate the detection and collection of geographic information. In the process of the continuous development and improvement of the surveying and mapping remote sensing technology used in this paper, the relevant data obtained from the survey are analyzed, which improves the accuracy and validity of the data information, and achieves the purpose of constantly updating the data information. it reflects the timeliness of remote sensing data information, which plays a certain role in promoting the establishment of geographic information system.

3.Measures to strengthen the application of remote sensing technology

Expand the application field

In order to improve the measurement accuracy of remote sensing technology and further expand its application field, the relevant state departments should strengthen the research and development of remote sensing technology, popularize and promote the application of remote sensing technology, and further expand the scope of application of remote sensing technology in practice; relevant departments should pay attention to the application of modern remote sensing technology in various fields of surveying and mapping and increase support for the development of remote sensing technology.

Vigorously popularize remote sensing technology

With the continuous application of remote sensing technology in geographical detection, it can analyze the exploration work in various complex topography and detect meteorological disasters, geological disasters and fire information in real time. In the process of survey and exploration, in order to carry out rescue work and understand the disaster situation, we should vigorously promote remote sensing technology and improve the popularity of this technology, so as to provide more effective basic support for geographical detection. Specifically, the relevant departments should increase capital investment and carry out technology popularization from the perspective of improving the spatial resolution of remote sensing technology. Remote sensing technology is highly consistent with geological work, therefore, the relevant personnel should improve the application level of remote sensing technology in geological detection and provide more effective measurement means for geographical detection work.

4.Concluding
