Construction coordinate system is converted to rectangular coordinate system in space by COORD software, while earth coordinates are also converted into space right-angle and are sat
Mark system establishes the two in the connection of rectangular coordinate system in space, Ke Yijian by seven parameter conversion methods in a space rectangular coordinate system
The path that vertical construction coordinate and geodetic coordinates are arbitrarily converted, realizes conversion of the construction coordinate to geodetic coordinates.
In order to solve the above problem, the specific technical solution of the present invention is as follows: what a kind of construction coordinate was converted to geodetic coordinates
Measurement method, steps are as follows: 1) point close to line midline is chosen in Measurement results table；2) applying a little will be chosen in step 1)
Work area mark and geodetic coordinates are directed respectively into different TXT documents；3) it opens COORD software and central meridian position is set；4)
With COORD software by step 3) construction coordinate and geodetic coordinates be converted into the space right-angle under respective coordinate system respectively
Coordinate；5) rectangular coordinate system in space is imported in TXT document and is saved；6) COSA software selection coordinate conversion operation TXT text is opened
Shelves establish the calculated relationship of construction coordinate and geodetic coordinates；7) construction coordinate of any position is imported into the TXT of opening relationships
COSA software is run in document obtains geodetic coordinates of changing the time in batches.
Construction coordinate is imported in TXT in the step 2) with point number, X, Y, Z-shaped formula；Geodetic coordinates with point number, latitude,
The form of longitude and elevation imports another TXT document.
The setting steps of central meridian position described in the step 3): setting is 1. clicked；2. map projection；3. from
Define Gaussian plane；4. central meridian, central meridian angle is corresponding with construction coordinate in step 2.
Rectangular coordinate system in space imports TXT text by the form of point number, XYZ, latitude, longitude and elevation in the step 5)
It is saved in shelves.
Bring of the present invention have the beneficial effect that using such method can batch realization construction coordinate to geodetic coordinates
Conversion, is simple and efficient, and avoids conventional method and calculates the probability for mistake occur, greatly reduces engineering risk.Have accurately
Coordinate information can accurately and efficiently navigate to the areal model of various structures or threedimensional model in satellite map,
The advanced positioning for realizing structural solid, specifies the relative positional relationship of complex linear engineering, and size casual labourer journey is carried out in map
It is quick planning, earth clearance planning, to engineering weight difficult point position carry out anticipatory analysis, greatly improve work efficiency, save
Duration creates economic benefit for enterprise.
Specific embodiment
A kind of measurement method that construction coordinate is converted to geodetic coordinates, steps are as follows: 1) choosing and connect in Measurement results table
