【摘要】：安慶市城市測量控制網(wǎng)改造采用現(xiàn)代大地測量方法,利用D級(jí)GPS控制網(wǎng)作為測區(qū)首級(jí)控制網(wǎng),以二等水準(zhǔn)點(diǎn)作為首級(jí)高程控制點(diǎn),布設(shè)7個(gè)點(diǎn)構(gòu)成骨架網(wǎng)。按照GPS網(wǎng)的可靠性指標(biāo)、精度指標(biāo)、效率指標(biāo)進(jìn)行優(yōu)化設(shè)計(jì),并進(jìn)行GPS二、三、四等水準(zhǔn)聯(lián)測,通過一定數(shù)量和分布均勻的GPS水準(zhǔn)點(diǎn)進(jìn)行高程擬合,其精度完全符合1∶500大比例尺測圖和城市規(guī)劃測量的精度要求,可供類似工程參考。
[Abstract]:The transformation of Anqing city survey control network adopts the modern geodetic method, using D class GPS control network as the first control network of surveying area, and taking the second leveling point as the first elevation control point, and setting up 7 points to form the skeleton network. According to the reliability index, precision index and efficiency index of GPS network, the optimization design is carried out, and the GPS leveling of two, three and four grades is carried out, and the height fitting is carried out through a certain number and uniform distribution of GPS leveling points. Its precision fully meets the requirement of 1: 500 scale surveying and urban planning surveying, which can be used as reference for similar projects.
