2000 surveying datum frame unification method and device and computer readable storage medium

Abstract

The invention provides a 2000 surveying datum frame unification method and device and a computer readable storage medium. The method comprises the following steps: establishing a CORS (Continuously Operating Reference Stations) base station major network of a target city and an equivalent precision CORS base station extended network; performing compensating computation on the CORS base station major network, the equivalent precision CORS base station extended network, a first control network, a second control network and a third control network respectively in a starting point transfer mannerby taking a base station of a provincial CORS system as a starting point, and obtaining CGCS 2000 geodetic coordinates, 1980 Xi'an coordinates and 2000 coordinates corresponding to base stations of the CORS base station major network, the equivalent precision CORS base station extended network, the first control network, the second control network and the third control network. According to the method, the datum frame is surveyed in a unified manner by taking the CORS system as datum, and dynamic maintenance and update of 2000 geodetic coordinates of the target city can be realized. Meanwhile,information sharing of the coordinate system can be realized, and convenience is brought to city management and city construction.

Description

technical field [0001] The invention relates to the field of urban coordinate conversion calculations, in particular to a method and device for unifying 2000 surveying and mapping datum frames, and a computer-readable storage medium. Background technique [0002] Surveying and mapping datum refers to the starting basis of the entire surveying and mapping of a country and the basis of various surveying and mapping systems, including various selected geodetic parameters, unified starting plane, starting datum point, starting position and related locations, facilities and names, etc. , my country's current surveying and mapping datums mainly include geodetic datums, elevation datums, depth datums, and gravity datums. Gravity basic network, elevation control network, national plane control network, and national GPS control network. [0003] At present, most cities in my country have long shared the status of multi-coordinate systems in terms of surveying and mapping benchmarks. ...

AI Technical Summary

Problems solved by technology

The coexistence of multiple sets of coordinate systems not only increases the cost and difficulty of information sharing, 2000 geodetic coordinate maintenance, and business connection, but also brings a lot of inconvenience and even contradictions to urban management and urban construction, causing unnecessary coordination and administrative risks
