0Introduction

The so-called digital earth is also referred to as a virtual system of the earth that uses the earth's coordinates as the basis, and at the same time, has the massive data of multi-resolution as well as multidimensional display. The digital earth is also referred to as a virtual system of the earth based on the earth coordinates with massive data of multi-resolution and multi-dimensional display. Digital Earth is seen as "a three-dimensional, multi-resolution representation of the Earth that is capable of containing large amounts of geographic data". Modern surveying and mapping science and technology is a science and technology based on computer technology, optoelectronic technology and network communication technology, coupled with spatial science and information science. With the continuous improvement of the global positioning system (GPS), the GPS, remote sensing and geographic information system (GIS) are taken as the core of the technology, and the original characteristics of the ground as well as the boundaries will be obtained through the means of surveying, reflecting the current status of the ground as the graphic and positional information for the planning and design of engineering construction and administrative management. Engineering construction planning and design and administrative management, thus creating favorable conditions for social production and development. With the development of science and technology, various technologies and theories have been greatly developed in various fields and industries of the current society, and a large number of advanced technologies and theories have emerged, and in the current digital earth and mapping science and technology is no exception, with a large number of advanced technologies and theories in digital earth and mapping science and technology, greatly improving the level of digital earth and modern mapping science and technology, thus laying a solid foundation for the development of social and economic development. This has laid a solid foundation for social and economic development. However, as far as the actual situation of digital earth and mapping technology is concerned, there are still some serious problems, which not only affect the development of digital earth and mapping technology, but also restrict the development of social economy.

In this paper, from the modern development of mapping science, the digital earth and modern mapping science and technology has been analyzed in depth, and then the development of digital earth and modern mapping science and technology has been elaborated in detail. I hope to be able to play the effect of throwing bricks to attract jade, so that peers discuss with each other *** with the improvement, and then for the development of China's digital earth and modern surveying and mapping science and technology to play a certain role in promoting.

1 modern development of surveying and mapping

With the development of society, the ability of mankind to transform nature is also increasing, so people urgently need to deepen the understanding of the Earth, so that better transformation of nature, thus promoting the sustainable development of human society.

Surveying and mapping is an important means for human beings to recognize nature and the Earth, and with the development of surveying and mapping, the level of people's knowledge of the Earth has also been greatly improved. Especially with the rapid development of computer technology in recent years, in the field of surveying and mapping has also increased the application of computer technology, which makes the modern level of surveying and mapping has been further enhanced. China's vast territory, the country's land area of 9.6 million square kilometers, and the use of modern surveying and mapping will be able to map our country to significantly shorten the duration of the work, thus freeing up much of the labor force, which effectively saves costs.

Today, fiber-optic cable communications, satellite communications, digital multimedia network technology can make mapping products from a single paper-based information into disk and CD-ROM and other electronic information, product distribution can be transferred from a single postal route to the "circuit" (digital communications and computer network fax), the form of surveying and mapping products and services to the community as a result of information technology to support the development of information technology has undergone great changes, to achieve the development of information technology. At present, with the rapid development of China's economy and the reform of economic ownership and operation system, there is a need to open up civilian national surveying and mapping products; from the technical point of view, the Western countries satellite geodesy technology can be produced in almost any region of the world 1m resolution (equivalent to 1:10,000 scale) of the maps, the satellite on the GPS can be included in the global reference frame and the conversion of such maps into their national coordinate system, medium and small-scale national maps have been confidential value.

2 Digital Earth and Modern Surveying and Mapping

All events on Earth occur in a certain spatial location, and the vast majority (about 80%) of the information needed for human socioeconomic activities is related to geographic location. About 40 of the 62 priority development projects of China's Agenda 21 require the establishment or application of geographic information systems (GIS). Digital Earth is a holistic information model of multi-resolution, 3-dimensional digital description of the Earth made using massive geographic information (i.e., geospatial data), which facilitates human beings to maximize the *** enjoyment and rational use of information resources, and provides a new means for human beings to understand, transform and protect the Earth, and the role of the framework of geographic coordinates is highlighted here in the concept of Digital Earth, and thus NSDI is the The infrastructure of the digital Earth requires the provision of a (geo)spatial data framework, including the geodetic control framework (National Positioning Network (NPN) and Gravity Control Network (GCN)), digital orthophotos, digital elevation models (DEMs), basic geographic datasets, such as roads, waterways, administrative boundaries, and public *** cadastre, and so on. On this framework, all kinds of natural information of the Earth and all human information needed and of interest, such as human socio-economic activities, are loaded. For the digital earth to provide the above geospatial data framework is the surveying and mapping industry itself "specialization", but also put forward a higher level of technical requirements for surveying and mapping.

3 Mapping and Geospatial Informatics

In the first part of this paper, the modern trends in mapping, driven by new technological advances, were discussed.

From the point of view of modern information theory, surveying and mapping is essentially a discipline about geospatial information. Traditional surveying and mapping is limited by ground measurement technology, spatial and temporal scale and accuracy level as well as inputs, and its products are mainly single topographic maps and specialized maps compiled and drawn on the basis of topographic maps. It cannot reflect, at least not in a timely manner, changes in the morphology of the Earth's surface, especially on a large scale and globally. Its products have a long production cycle and can no longer meet the multiple needs of the rapid development of regional and global economies. Information technology has accelerated the operation of human society.

Surveying and mapping should be to provide information on the natural environment of human living space and its changes in the discipline of the subject connotation has changed dramatically, so how to define the meaning of surveying and mapping, has been the world's surveying and mapping workers concerned about the problem. Thus, from the 1990s, the international community changed the term Surveying and Mapping to a new term to accurately reflect the essence of the discipline, and the term Geomatics came into being. Subsequently, the mention of Geomatics has become a hot topic in China's academic circles, mainly in the field of geomatics. Due to the different understanding of its meaning, its Chinese translations are also diverse, and now it is translated as "geospatial information science", which has basically been recognized. Regardless of how people understand the meaning of Geomatics, according to the standard definition of ISO and the definition of "Geomatics" by IUSM, the meanings of the two are basically the same, except that the scope of geospatial information involved in Geomatics is wider. Geomatics more accurately describes the status and role of mapping in the modern information - communication society, adapted to the characteristics of the modern society on the great demand for geospatial information, and thus develops and improves the field of research and work of mapping, in line with the reality of the development of modern surveying and mapping.

4 Concluding Remarks

With the application of these mapping technologies and mapping theories, the level of modern mapping science and technology has been effectively improved, thus laying a solid foundation for helping people to understand the Earth and promoting economic development. Through this paper on the digital earth and modern mapping technology in-depth analysis, coupled with a detailed description of the development of digital earth and modern mapping technology, I believe that readers also have a deeper understanding of it.

In conclusion, digital earth and modern mapping technology is an important means to promote social development, therefore, in order to further improve the level of modern surveying and mapping, it is also necessary to increase the analysis of its research efforts.

0 Introduction

Surveying and mapping is a prerequisite for the development of national economy, cultural construction, and social development, and a fundamental part of a country's geographic information industry. It is the basic component of a country's geographic information industry. It provides a variety of thematic and comprehensive basic information related to geographic location for national economic construction and social development, and its results are essential basic information for resource investigation, environmental monitoring, farmland construction, energy, transportation, water conservancy and other large-scale construction projects, urban and rural planning and construction, land development and utilization, major disasters, monitoring and forecasting, and scientific research, national defense construction, as well as the national macro-management decision-making. From the early 1980s, the surveying and mapping industry began to embark on the technical transformation of traditional surveying and mapping means and production processes, and carried out digital mapping, machine-assisted map making, map database, geographic information system (GIS), human-safety laser ranging (SLR), global positioning system (GPS), remote sensing (RS) and other aspects of the basic research and applied research. Although China's surveying and mapping industry has made great progress, however, its overall technical level with the international advanced level of surveying and mapping, there is a large gap, far from meeting the needs of national economic construction and social development, which is mainly manifested in: digital surveying and mapping technology system of a number of key technical issues have not yet been resolved, the complete digital surveying and mapping technology system has not yet been formed; surveying and mapping production in the production of slow production, update The situation of slow production speed, long updating cycle, single product form and low quality of map printing in the production of mapping has not yet been fundamentally transformed; basic theoretical research on mapping is relatively weak, especially in the fields of remote sensing, geographic information system (GIS), map cartography, etc., which seriously affects the further development of the technology; the level of comprehensive development and application of mapping information is relatively low, and the integration of high and new technologies of mapping is still in the beginning stage, and the competitiveness of mapping technology is relatively weak in the international market, and the international cooperative research to participate in global issues is not yet in the beginning stage. Participation in international cooperative research on global issues has yet to be further expanded. In this paper, how to promote the development of China's mapping geographic information science and technology to do the following recommendations.

1 actively promote the construction of basic geographic information resources

First, the use of new technologies, new techniques, to strengthen the transformation and optimization of the basic geographic information system upgrades, and actively carry out the construction of various types of thematic databases at all levels. We will place the updating of basic geographic information in a more prominent position, step up research on the establishment of a mechanism for updating basic geographic information under the conditions of the new situation and new technology, accelerate the pace of information updating, and effectively improve the current status of basic geographic information. Secondly, the integration of various types of basic geographic information resources at all levels should be strengthened, and information***sharing between surveying and mapping departments at all levels, as well as between surveying and mapping departments and relevant departments, should be actively promoted, so as to realize the integration and application of basic geographic information data from different data sources, of different types and at different scales. Thirdly, to form a platform of basic geographic information *** enjoyment of central and local surveying and mapping departments with hierarchical management, unified standards, complete types and interconnections as soon as possible, so as to create more favorable conditions for realizing rapid transmission and full use of basic geographic information of surveying and mapping departments.
