The online spreadsheet service EditGrid allows users to easily generate kml features in google maps. Currently, the Grid2Map addon which enables this function only supports the creation of point or line features. It would also be nice if there was an option to plot polygon features as well.
The ability to link online spreadsheets to web mapping hints at more sophisticated GIS capabilities waaaaay down the line. The ability to attached (multiple) attributes in tabular form is the essence of vector based GIS.
Heres an example:
The EditGrid spreadsheet containing a few points, and the resulting Google Map with points only, and with points and lines.
The formatting is rather crude, but bearing in mind that this took approx 5 minutes, not too bad. A rather nice and user friendly way of generating some points/lines in Gmaps.
Cool.
