Proj.NET支持基准面转换，地理坐标系，投影坐标系，地心坐标系，可在多种.NET框架下使用，并支持SilverLight。它可进行点对点之间的坐标变换，同时也可以把坐标系转换为 Well-Known Text (WKT) 和 XML。目前支持投影类型有：Mercator、横轴墨卡托投影(Transverse Mercator)、Albers、正轴等角割圆锥投影(Lambert Conformal Conic、兰勃特投影）等。(Proj.NET supports datum plane conversion, geographic coordinate system, projection coordinate system and geocentric coordinate system. It can be used in a variety of.NET frameworks, and supports SilverLight. It can coordinate between points, and coordinate system can be converted into Well-Known Text (WKT) and XML. The support projection type: Mercator, transverse Mercator projection (Transverse Mercator), Albers, normal secant conic conformal projection (Lambert Conformal Conic, Lambert projection).)
