Allow users to rate environmental factors for their automatically geocoded location

I just created the above topic here http://groups.drupal.org/node/28044 on Drupal Groups - Location and Mapping.

Perhaps your module could be used to input the location data into other modules that would provide a form for people to do what I describe below. Can location information be acquired more precisely for anonymous users without requiring them to enter it manually? Perhaps people can indicate their location by clicking on a structure in a Google map, for example.

Users could indicate their location by clicking on a structure in a Google map, for example. This would make it more friendly for mobile device users than having to enter alpha numeric information, at least for selection at the medium-close range - like the structure or building.

My objective is to create a site that would allow people to rate the environmental factors of their immediate physical space.

Example use:

While at a performance or presentation a person is able to subjectively rate room temperature and other factors. With a mobile device the person can go to a simple web address which will provide as much of the location information as possible and provide fields for missing details such as building and room number with auto-fill updating from previous user input. Time and date would be handled by the server. The person would then rate the room as too cold or too hot either (2 choices) or possibly a scale of 5 from too hot to too cold.

I would like provide that information to facility management in report form, live from Drupal or both. Such report would ideally have the day, time, location and rating information with the greatest possible detail on the location information.

I have not worked with Drupal geo / location modules before the last few days. I see that there are many modules available which make using terms that are not yet familiar to me. I would appreciate some advice on where and how I should proceed.

Thanks for your time.
