DESIGN OF COOPERATIVE UPDATE MECHANISM OF NATIONAL RESOURCES INVESTIGATION AND BASIC SURVEYING AND MAPPING

National resources investigation and basic surveying and mapping are two important tasks of the surveying and mapping department, and they are similar in production organization and technology realization. In the process of operation, both of them need to carry out internal collection, base map production, field verification and so on. It is operationally feasible to carry out cooperative production of national resources investigation and basic surveying and mapping. From the perspective of technical process and method, both of them are carried out by combination internal and field work. Firstly, based on remote sensing images and thematic geographic data, the internal work will perform image interpretation. Then, the field verification will be carried out to make judgments and adjustments. Finally, the results of the field verification will be transferred back to the internal work, and the data will be further edited and organized in the internal work to obtain the final data. This paper analyzes the technical methods and workflow of the cooperative update mechanism of national resources investigation and basic surveying and mapping. It will enable one-time acquisition of data needed for the national resources investigation and basic surveying and mapping. It is conducive to unifying the classification system, technical standards, survey methods, establishing a natural resource data service system, and improving the natural resource data sharing working mechanism. Realize the overall control of the land space, solve the contradictory problems such as multiple doors, uneven thickness, repeated crossover, etc., advance data integration and deep development and utilization by using big data technology and data analysis model. 1. GENERAL INSTRUCTIONS For a long time, China’s natural resources in our country have been managed separately, and natural resources investigation work has been organized separately, which leads to duplication and overlap in the object, scope and content of the investigation. The results of the investigation are contradictory, which is not conducive to the systematic management of mountains, rivers, fields, lakes and grasses as a community of life. In March 2018, the establishment of the Ministry of Natural Resources created a new situation for the development, utilization and protection of natural resources. Unified natural resource data is the fundamental guarantee for the implementation of natural resource use control. After the establishment of the Ministry of Natural Resources, the investigation of natural resources is imminent. Relying on the existing basic surveying and mapping achievements, the "six unified" natural resources investigation system of "unified organization, unified laws and regulations, unified investigation system, unified classification standards, unified technical specifications, unified data platform" is constructed. The present situation of all kinds of natural resources covering land and sea areas is clarified, and all kinds of natural resources are collected and acquired.

DEFINITION OF NATURAL RESOURCES INVESTIGATION Natural resources refer to the general term of natural environmental factors that can produce economic value and improve the current and future welfare of human beings under certain time and technological conditions. They provide material and space for human survival, development and enjoyment. The natural resources elements managed by the Ministry of Natural Resources include land, minerals, forests, grasslands, wetlands, water and oceans. Natural resources such as sunshine, air and climate are not included. At the same time, considering the natural resources utilization and actual management needs of the island, in the natural resources investigation and monitoring work, the human geography and other factors closely related to natural resources are


GENERAL INSTRUCTIONS
For a long time, China's natural resources in our country have been managed separately, and natural resources investigation work has been organized separately, which leads to duplication and overlap in the object, scope and content of the investigation. Unified natural resource data is the fundamental guarantee for the implementation of natural resource use control. After the establishment of the Ministry of Natural Resources, the investigation of natural resources is imminent. Relying on the existing basic surveying and mapping achievements, the "six unified" natural resources investigation system of "unified organization, unified laws and regulations, unified investigation system, unified classification standards, unified technical specifications, unified data platform" is constructed. The present situation of all kinds of natural resources covering land and sea areas is clarified, and all kinds of natural resources are collected and acquired.

The natural resources investigation is about to be widely carried out, the relationship between natural resource investigation and basic surveying and mapping will be deeply considered, and the advantages of both will be fully utilized, which will be beneficial to the innovative natural resource investigation model, help to expand the application field of basic geography and help to conducive to cost savings.

Cnsistency of Data Source
Natural resource investigation are similar to basic surveying and mapping data sources, mainly high-resolution aerospace remote sensing images and thematic data of water conservancy, agriculture, forestry, land, civil affairs and other industries.

Similar of Technical Route
Natural resource investigation and basic surveying and mapping have similarities in production organization and technology and improve production efficiency and labor value.

Content Overlap
The basic surveying and mapping data are rich in content, detailed in classification and wide in scale, including water system, residential area, transportation, pipeline, vegetation and soil, landform, boundary, place name and other information. It has the characteristics of high geometric accuracy, detailed classification and strong current situation, and does not involve the ownership and management relations of various elements.
On the basis of basic surveying and mapping data and integrating the special data of natural resources of relevant industry departments, the spatial and physical nature of natural resources of mountains, rivers, forests grassland and lakes is carried out. Through statistical analysis, the stock and change of natural resources assets are obtained, which provides a basis for government departments to find out the "family background" of natural resources assets and their changes. However, the most basic geospatial data results.

Realistic Needs
The convenience and efficiency of natural resources investigation can be improved by using basic mapping data and related technologies.
1) It provides a convenient and efficient way of data acquisition from scattered to specialized, in order to cope with increasingly complex geographical information.
