Low-cost Easy-to-Deploy GIS Data Collection

Joseph Kerski, Education Manager at ESRI, wants to know who is using the new GIS data collection tools that can map results in ArcGIS online or in ArcGIS for Desktop. 

Dr. Kerski provides the following link of one of these new tools that can easily be left on the landscape to collect data: Air Quality Eggs


Dr. Kerski also provides the following link regarding an app for smartphones that collects "noise pollution" data:

Wow!  Has anyone used an Air Quality Egg here in Hawai`i during the burning of the sugarcane fields?

Has anyone tested the level of noise pollution in your area and compared it with other areas?

Please share your data collection experiences!
