【摘要】:隨著空間測(cè)量技術(shù)的普及和精度的進(jìn)一步提高,,傳統(tǒng)的大地測(cè)量工作發(fā)生了質(zhì)的變化,促使大地坐標(biāo)系由參心坐標(biāo)系向地心坐標(biāo)系轉(zhuǎn)化。自2008年7月1日起,我國(guó)全面啟用地心坐標(biāo)系統(tǒng)—2000國(guó)家大地坐標(biāo)系,這意味著國(guó)家及各省市的測(cè)繪活動(dòng)必須在地心坐標(biāo)系下進(jìn)行。此前全國(guó)各種測(cè)繪成果絕大部分采用參心坐標(biāo)系成果。要采用地心坐標(biāo)系,存在著兩個(gè)坐標(biāo)系的差異問題,必須進(jìn)行坐標(biāo)系的轉(zhuǎn)換。因此,完成現(xiàn)行參心坐標(biāo)系成果向2000國(guó)家大地坐標(biāo)系轉(zhuǎn)換是使用和推廣2000國(guó)家大地坐標(biāo)系的一項(xiàng)重要工作。 本論文介紹了坐標(biāo)系相關(guān)的理論知識(shí),詮釋了我國(guó)現(xiàn)行國(guó)家大地坐標(biāo)系的相關(guān)情況。在結(jié)合大地測(cè)量應(yīng)用技術(shù)及已有資料成果的基礎(chǔ)上,根據(jù)控制點(diǎn)的分布情況,分別采用分區(qū)轉(zhuǎn)換法和整體轉(zhuǎn)換法等多種坐標(biāo)轉(zhuǎn)換模型,計(jì)算格網(wǎng)點(diǎn)坐標(biāo)轉(zhuǎn)換改正量。通過比較兩種轉(zhuǎn)換方法的優(yōu)缺點(diǎn),最后提出采用整體轉(zhuǎn)換法計(jì)算全國(guó)高精度高分辨率格網(wǎng)改正量的方法。 本文重點(diǎn)研究了1980西安坐標(biāo)系向2000國(guó)家大地坐標(biāo)系格網(wǎng)改正量計(jì)算。利用內(nèi)插法和空點(diǎn)法對(duì)格網(wǎng)改正量的內(nèi)符合性進(jìn)行精度檢驗(yàn),通過繪制改正量分量DB、DL立面圖檢驗(yàn)改正量的連續(xù)性。 簡(jiǎn)單論述了利用1954年北京坐標(biāo)系轉(zhuǎn)換到1980西安坐標(biāo)系已有的成熟、高精度的方法(坐標(biāo)改正量法),計(jì)算1954年北京坐標(biāo)系轉(zhuǎn)換2000國(guó)家大地坐標(biāo)系格網(wǎng)改正量的方法。
[Abstract]:With the popularization of the spatial survey technology and the further improvement of the precision, the traditional geodetic work has undergone qualitative changes, which promotes the transformation of the geodetic coordinate system from the reference coordinate system to the geocentric coordinate system. Since July 1, 2008, the national geodetic coordinate system -2000 has been fully used in China, which means that the surveying and mapping activities of the country, provinces and cities must be carried out in the geocentric coordinate system. Before that, most of the surveying and mapping achievements in China were based on the results of the reference coordinate system. In order to adopt the geocentric coordinate system, there exists the difference between the two coordinate systems, so the coordinate system must be transformed. Therefore, it is an important work to use and popularize the 2000 national geodetic coordinate system to complete the transformation from the current reference coordinate system to the 2000 national geodetic coordinate system. This paper introduces the theoretical knowledge of coordinate system and explains the current situation of national geodetic coordinate system in China. Based on the application of geodesy technology and the existing data, according to the distribution of control points, several coordinate transformation models, such as partition transformation method and integral transformation method, are used to calculate the grid dot coordinate transformation correction. By comparing the merits and demerits of the two conversion methods, a method of calculating the high precision and high resolution grid corrections of the whole country by using the integral transformation method is put forward. This paper focuses on the calculation of grid corrections from 1980 Xi'an coordinate system to 2000 national geodetic coordinate system. The interpolation method and the space-point method are used to test the accuracy of the inner conformance of the grid corrections, and the continuity of the corrections is verified by drawing the DB-DL elevation diagram of the correction components. This paper briefly discusses the mature and high precision method (coordinate correction method) which has been used to convert Beijing coordinate system in 1954 to Xi'an coordinate system in 1980. The method of calculating the grid correction of 2000 national geodetic coordinate system in Beijing coordinate system in 1954 is discussed.
