You may have heard the term Mash-up.  In online speak, it means taking data from one place, combining it with the software from another site, and creating a third, very useful, if single focus site.

We have been playing with MapaList which is the combination of Google Maps, Google Spreadsheets (an online copy of Excel) and an address list of your customers.  The result is a very simple way of visualising infomration.

Have a look at our latest project, a list of all the businesses on the Deeside Industrial Estate.

You will, very quickly realise where the limitations are with a system like this!  Postcodes all have the same Geotag so there is only one pin per postcode.  This isn’t useful for our project, but if you were working over the whole county, it would be much better.
