Points2Dto3D。将二维点的坐标软换成三维坐标，即增加了高程点Z坐标。-Points2Dto3D. Softly change into the three dimensional coordinates the two-dimensional spot coordinates, namely increased the elevation to select the Z coordinates.

GIS(地理信息系统)中，需要将经纬度坐标(度分秒的形式)转换成大地坐标(xy的形式)，这个程序就能派上用场了，基于北京54坐标系。如果换成西安80，把里面的参数改改就可以了。

能够实现各种坐标的转换：投影面归算、椭球体变换、七参数计算、地图投影及换带变换,大型基建施工工程精度保障。 操作方便：支持与Excel表格的双向粘帖复制。-To achieve a variety of coordinate transformation: projection plane owned by operator, ellipsoid transform, seven-parameter calculation, map projection and for zone chang

大地坐标间换，从WGS84坐标转换为北京54，采用七参数法-Geograph coordinate transform, From WGS84 Coordinate to Beijin54, aceepting seven parameters
