Life in 1984
Personal Computer’s just coming into use

No Internet but we had Beta Max

No GPS …….but we had Spinal Tap!!!And the birth of WGS 84
![Page 11: Cunningham low cost gis](https://reader033.vdocuments.mx/reader033/viewer/2022052413/55985d4f1a28ab5f768b485e/html5/thumbnails/11.jpg)
WGS 84
- GPS Satellite Positioning System
- a Big Deal
- Military Usage only at first
Now it’s old enough to buy cheap car insurance

GIS in 1984
ESRI, Autodesk, GE, Intergraph, Bentley
Large companies,
Big solutions,
System approach to things
Expensive solutions

What is GIS Today
Is it overlaying a map on Google Earth?
Is it a pdf of a town parcel?
Is it using an iPhone to map a proposed walking path through your town
Is it scanning in old CAD drawings and referencing
Is it consuming state LiDAR data to do flood mapping
![Page 18: Cunningham low cost gis](https://reader033.vdocuments.mx/reader033/viewer/2022052413/55985d4f1a28ab5f768b485e/html5/thumbnails/18.jpg)
What is GIS Self Sufficiency
Self-sufficiency is knowing what you know and what you don’t know.
“Eat the bear,”“It’s low cost GIS”

The Cloud is to GIS Software as what is to what?
A. An e-reader is to books

Answer: All of the above
It’s a hosting and delivery mechanism
Don’t give up your ownership of your data …..Caveat Emptor Trust me, it will be ok
