1 Introduction

This article introduces the integration of English for Specific Purposes (ESP) into the university English curriculum system and its teaching practices in the field of surveying and mapping English. The author's school has explored the construction of ESP courses, including the English translation of "Fundamentals of Geodesy". The main translator, based on functionalist functionalism, summarized common problems in the English translation of surveying and mapping literature and proposed strategies to optimize the quality of translations, aiming to provide reference for relevant literature translation and academic paper publication.

Practice of translating "Fundamentals of Geodesy" into English

Fundamentals of Geodesy "is an important textbook in the field of surveying and mapping, first published by Surveying and Mapping Press in 2010 and updated in the second edition in 2016. The book comprehensively covers the core issues of surveying and mapping, including surveying and mapping benchmarks, geodetic control networks, geoid, elevation systems, reference ellipsoids, geodetic coordinate systems, Gaussian projection, UTM projection, plane coordinate systems, and the establishment of geodetic coordinate systems. The book also introduces relevant geodetic data collection techniques. The English version is published by Springer Publishing in Germany, and after being reviewed and language proofread by multiple experts, its quality has been recognized. In 2017, it became one of Springer's "best-selling 50% e-books". Based on the English translation practice of this textbook, this paper explores the problems in the Chinese English translation of surveying and mapping literature, and proposes translation strategies and measures to optimize the quality of translations from a functionalist perspective.

The main issues in the English translation of "Fundamentals of Geodesy"

In the English translation of "Fundamentals of Geodesy", translators face three major issues: understanding professional knowledge, standardizing professional terminology, and ensuring equivalence between source and target language texts. Firstly, the translator needs to have a deep understanding of professional knowledge, such as gravity measurement, direction correction, ellipsoid positioning, etc., in order to accurately express themselves. Secondly, the translation of professional terms should be in line with international standards, for example, "reference center coordinate system" should be translated as "local coordinate system". Finally, the translator needs to fill in the information asymmetry between the source language text and the target language text on the basis of understanding the author's intention, such as translating "Technical Standards" as "Technical Standards". Skopos theory is an effective theory for guiding the translation of scientific and technological literature, and translators should choose appropriate translation strategies based on the needs of the target audience.

Translation of Objective Theory and Surveying Literature from Chinese to English

In depth exploration of the communicative model in the translation process, emphasizing the translator's subjectivity in translation and the influence of translation objectives on strategy selection. The English translation of "Fundamentals of Geodesy" aims to serve researchers and learners in the field of surveying who are native English speakers or working languages. The translation is required to have cross-cultural communication capabilities, readability, and accuracy in scientific literature. The German functionalist teleology, including Reiss, Vermeer, M ä ntt ä ri, and Nord's theories, provides a teleological perspective for translation, emphasizing that the selection of translation strategies and methods should be based on the translation purpose. The three principles of functionalism - the principle of purpose, the principle of coherence, and the principle of fidelity - guide translators in pursuing the expected function of the translation.

5 Conclusion

The paper is based on the English translation practice of the textbook "Fundamentals of Geodesy", summarizing common problems in the translation of surveying and mapping literature from Chinese to English, such as understanding professional knowledge, standardizing terminology, and language equivalence. It also proposes a translation strategy based on functionalist purpose theory, aiming to improve the quality of scientific and technological translation and provide reference for the English translation of surveying and mapping literature and international publication of academic papers.
