Trailhead screen capture
is a tool to allow you to view (visualize) your data or information.
If you look at things in your classroom or school yard that you
might want to organize into a database you will notice that everything
has a Geographical Location. Things are in a certain place or
move from place to place. Each of those "places" or
locations has a latitude and longitude.
adding the Latitude and Longitude to your database of things you
can make a GIS map.
more exciting is the fact that once you've made that map you can
go and search for information attached to that map.
may want to find all the water fountains in your school yard or
all the oak trees in your yard.
GIS you can make a map that has both the water fountain list and
the oak tree list, goto the map and ask it to display only the
oak trees and the information on those trees.
GIS map becomes a source of information and a map you can change
depending on what you want to look for.
