wgstobd: WGS84 to BD09

In versey-sherry/ChinaCoordinate: An R package for converting Chinese coordinates (GCJ02 and BD09 coordinates) to WGS84 coordinates and vice versa.

Description

Function to convert WGS84 coordinates to BD09 coordinates.

Geographic data from Baidu and coordinates in Baidu maps are BD09 coordinates. Geographic data from Chinese official websites and coordinates from Chinese map providers such as Gaode and QQ map are GCJ02 coordinates. GCJ02 coordinates is the first encryption applied to WGS84 coordinates. BD09 adds one more layer of encryption on top of GCJ02.

Usage

wgstobd(coordinates)

Arguments

coordinates

A vector of coordinate pair c(lat, lon)

Value

lat, lon

Examples

#Coordinate data eg. c(39.8659, 116.3597)
#Convert to BD09 coordinates

wgstobd(c(39.8659, 116.3597))
