Just a quick note to say that if you're having trouble generating DSPL for
geographic data, you might like my new program Magic Maps (Mac only):
After importing CSV data and/or KML files, you can export the merged data as
a DSPL file that will work with the Public Data Explorer.
If you find bugs or have questions about Magic Maps, feel free to email me
or send a note to our mailing list.
All the best,
