is
not
Special (?)

14. Spatial is Special?
NO! YES!
● Data are data ● Maps are the power
● The Geographical
Information
Systems are very
well defined
The map simplifies the complexity
Spatial is Indeed Special…but GIS Software Skills will Soon be Obsolete

15. The GIS recipe
● Projections
● Data models
● Analysis
● Rendering

16. Projections

17. Ex. Cilindric projection
(X,Y)

18. Datum
geoid
Ex.
World Geodetic System 84

19. Universal Traverse Mercator
source: USGS

20. UTM Zone

21. The most used in web devel.
● EPSG:4326 - WGS84
– Degree (lat/long)
– WGS84
● EPSG:900913 – Google Mercator
– Meters
– WGS84
– World without polos
● Digit version of the word GOOGLE

Vectors with Matrix
attributes Ex.
Points Digital Elevations Models
Lines Solar Power cells
Polygons Orthophotos
