What is GIS? |
GIS (Geographic Information Systems) is a
collection of computer hardware, software, and geographic data
for capturing, managing, analyzing, and displaying geographically referenced information. |
|
|
It takes numbers and words from the
rows and columns in databases and spreadsheets and puts them on a
map. |
