Research on Normative Expressions of Geomatics Elements From the Perspective of Quality Inspection

Abstract

Abstract. At present, social and economic development has entered a new era. The establishment of the Ministry of Natural Resources has strengthened the functions of the natural resources department to provide the government and the public with standard, accurate, authoritative and reliable geomatics data recognized by various sectors, and has also put forward higher requirements for the quality of geomatics data.The definition of some elements in the geomatics standards is ambiguous or even contradictory, which interferes with the work level of production personnel, affects the ability of quality inspectors to determine quality problems accurately and efficiently, reduces the consistency of geographic information data, and limits the promotion and use of the products.The fundamental way to solve this problem is to unify the understanding of products, quality inspection and application, to comprehensively consider different scales, different terrain types and different types of results, and to define geomatics elements precisely, clearly and uniformly so that practitioners in different links can reach a consensus and have no ambiguity in the understanding of the elements. This work is not only conducive to reducing friction among products, quality inspection and application, but also the basis for realizing the co-construction and sharing of geographic information data among various sectors.
