While working on the latest module of the UNIGIS master
course, I am beginning to get acquainted with various online map services. One
of the more interesting ones is the ArcGIS Explorer Online, available at http://www.arcgis.com/explorer.
The website offers many interesting user-made theme maps,
such as World AIDS Day Map, Import and Export of Plastic Waste, Forest Areas in
Europe, etc. These maps can serve as a good starting point or illustration for
a student investigation or visual information for the interested public.

But the real benefit of this map service is the ability to
create (and publish) one’s own theme map. The ArcGIS Explorer offers base maps
where a user can easily add information of interest, explore overlays and see
associated data. You can look for information shared by other users based on keywords, import your own data or use your previously stored information.

In this way, the user can explore publicly available or
personal data without the need for a professional and expensive software, and
what is more, share this information with people he/she chooses or publish it
for everyone to access.
For example, I investigated the occurrence of wildfires in the United States and produced a map that can be accessed here. It is fun and easy, really a tool for everyone.
