This converter will take latitude and longitude coordinates from WGS84 (the standard used by most web mapping services) and convert them to WKT points in the Spherical Mercator projection that Neatline uses.

To use it, enter your coordinates as "latitude,longitude" or "y,x" pairs. You can convert multiple pairs at once, just put them on new lines. When you click "Convert!", the converted coordinates will appear in the output box, ready to be used by Neatline.

This converter is based on a code snippet written by Wayne Graham, which you can find here:
