- <h1>Welcome to Proj4js</h1>
- <p>
-This is a JavaScript library that provides methods for coordinate
-transformations between map projections and longitude/latitude,
-including datum transformations, in a web client.
- </p>
-
- <p>
-To use the Proj4js, you first create a source and destination Proj4js.Proj
-objects, passing in a projection code (e.g. EPSG:4326).
-You can then use the Proj4js.transform() method, passing in map XY as a point
-object and the source and destination projection objects,
-and it returns the point coordinate in the destination projection.
