Learning the concepts of GIS
through Powerpoint and
ExcelGIS is a powerful tool that demands consistency and an understanding ofspatial scales, as well as the connection between data tables and the pictureson 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 andrelate data to the points or polygons.
The Tacoma Nature CenterSnake Lake Wetland Complex
This is an aerial photo of The TacomaNature Center provided by NatureMapping.
Insert a picture and size it to your slide.
Make a Duplicate slide and begin work in that slide (#2)
Wetland Monitoring Sites
Slide #2Using the Draw Menu, select circles and placethe circles where the monitoring sites occur
Number the sites using the Text box and fill

Select AutoShapes, then Lines, and thenthe icon that shows a polygon.
Begin drawing your monitoring habitat anddouble click to close the line. It may automatically fill in with a color and changecolor fill to “none”
Draw each of the habitats and create a Legend

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 alsobe selected) or hold the Shift Key down andhighlight each point.

Repeat the process from the previous slideand add the location numbers.
You have now created a point and polygonGIS map.
Creating a Spreadsheet (Table)
that corresponds (relates) with your monitoring sites
Develop a Data Collection Form or use the NatureMapping Data Collection Form
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 are ready to use GIS software.
