GIS

Question Answer
1) I can describe where CSUCI is located using different formats of lat/lon. DD: 34.25o , –118.00o
DMS: 34o15’00” , -118o00’00”
2) I can write out a basic definition for “GIS”. Geographic information systems are a special class of information systems that keep track not only of events, activities and thing but also where these happen.
3) I can describe why GIS data is special. Everything that happens, happens somewhere in space and time
Multidimensional ( x1y1, or xy,z ,t)
4) I can describe why and where GIS began. The Canadian GIS (CGIS), designed in the mid 1960’s as a computerized map measuring system. 1963 development of Canada GIS lead by Roger Tomlinson. The system was needed to analyze Canadians national land inventory and pioneered many aspects of GIS.

Hardware
Software
Data
Network
Procedure
6) I can convert from lat/lon DMS to DD. To convert from dms to dd use: A + B/60 +C/3600
7) I can describe how measures of lat are not equal to measures of lon. Lat lines don’t curve like the Earth as Lon lines do.
Length of degree of long = cos(lat)*111.325km
8) I can give examples to distinguish operational temporal scales from tactical. Operational temporal scales are short term.
Tactical temporal scales are medium term
