Map-It: Form-based Simple Map Generator


This form takes longitude/latitude pairs as input and plops 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 yeild a nice map of Cape Cod, Massachusetts, generated by supplying the longitude and latitude values of Cape-area towns: Woods Hole, New Bedford, Nantucket, Chatham and Provincetown.

Enter the lon/lat pairs in the box below:
- One pair per line.
- West longitude is negative.
- Digital degrees only.
- To cross the date line, use East longitudes (eg. 170 to 190.

Select the method to plot points: dots connecting lines dots & connecting lines don't plot the points!

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!

Press this button to submit the query:

The map is by "pscoast," part of the freely available GMT package, version 3. The form processing, GMT script generation and execution, and image manipulation is accomplished by an ugly little Perl script .
