Transcript Powerpoint Presentations to mimic GIS

Learning the concepts
of GIS through
Powerpoint and Excel
GIS is a powerful tool that demands consistency and an understanding of
spatial scales, as well as the connection between data tables and the pictures
on the screen.
Powerpoint and Excel are programs that can teach you the interconnectedness
of GIS data layers. The following is a tutorial of how to develop a GIS layer and
relate data to the points or polygons.
The Tacoma Nature Center
Snake Lake Wetland Complex
This is an aerial photo of The Tacoma
Nature Center provided by NatureMapping.
Insert a picture and size it to your slide.
Make a Duplicate slide and begin work in that

Select AutoShapes, then Lines, and then
the icon that shows a polygon.
Begin drawing your monitoring habitat and
double click to close the line. It may
automatically fill in with a color and change

Make another duplicate slide of the habitats
and aerial photo.
Go to each slide that has just the points and
from the File Menu, Select All (the text will also
be selected) or hold the Shift Key down and
highlight each point.
From the File Menu, Select Copy and then go
to this slide and Paste. Repeat for all points

Replace Column B title with “Site” and place
your Site numbers in there.
Data can be sorted by Site number. This
table can be imported into GIS when you
