GPS坐标转化(国外英文资料) Abstract] to use EXCEL spreadsheets for gauss projection conversion method was introduced in detail, analyses how the GPS coordinate system transformation, this paper proposes a simple and practical correct coordinate transformation method, this paper introduces the complete transformation with EXCEL. [key] electronic form; GPS; Coordinate transformation As a cutting-edge technology, GPS, can fast and convenient to determine the point coordinates, both operational and accuracy, than other conventional measuring equipment such as total station has obvious advantages. Along with the continuously to establish differential GPS stations around and the SA policy cancelled, makes the single positioning accuracy is greatly improved, some have reached the Amish level precision, can satisfy the survey of land and resources, land use renewal, remote sensing monitoring, the application of inventory, such as the right to use sea areas work. In general, we use the Beijing coordinate system 1954 or 1980 xi an coordinate system (hereinafter referred to as 54 respectively series and 80 series), and the coordinates of GPS measurement is WGS - 84 coordinate system coordinates, to coordinate system transformation. For the measurement of professional staff, although GPS positioning operation is very easy, but difficult to master, coordinate transformation is a universal spreadsheet software EXCEL, able to deal with more complex math, to use it for GPS coordinate transformation, area calculation will be very easy for you. For the transformation of the frame, the method of converting to EXCEL and the method of GPS coordinate conversion are described below. One, use EXCEL for the gaussian projection From the latitude and longitude BL to gauss plane rectangular coordinate conversion XY (gauss projection is to calculate), or in the conversion from XY BL (calculated by gauss projection), general need specialized computer software to complete, in the current popular conversion
