I initially tried to use Google Docs to do this, because I thought it should be relatively easy to map data from a Google Spreadsheet. I thought that this would be an initial usage scenario. It seems that it isn't. So, instead I used BatchGeo. They have a pretty quick and easy service, complete with Geocoding.
Here is what their online tool created when I gave it the CSV file:
View Wellington NZ, EQP Buildings in a full screen map
The full screen map includes a list of the locations mapped.
Of course, the next morning, I found out that James over at maptd used Google Fusion Tables, which allow you to directly map data from a spreadsheet onto Google Maps. I'll have to look into them next. I would like to be able to keep the grouped view that BatchGeo provides in any reworking.
