Map-It: Form-based Simple Map Generator

Sample image of the reulting topo mapSample image of the reulting mapThis form takes longitude/latitude pairs as input and plots them on a Mercator projection map along with land/sea and political boundaries. The map bounds will be about 10% larger than the bounds of the entered data points.

The default values on the form below yield a nice map of Cape Cod, Massachusetts, generated by supplying the longitude and latitude values of Cape-area towns: Woods Hole, Nantucket, Chatham, Provincetown and New Bedford.

1. :

- One pair per line.
- West longitude is negative.
- Digital degrees only.
- To cross the date line, use East longitudes (eg. 170 to 190).
- To plot the whole world use a longitude range from -180 to 180,
and latitude from -75 to 75, and use the "exact map extent" option below


2. Select method to determine map extent:

add 10% to map extent

Please wait for your map to be generated! If you abort and reload the form, you'll just create another process that will slow things down even more!
