Problems of Classical Paper Map
Keeping Paper map is unfavorable
Location and Attribute Information can’t be seen to-gether
It may produce millions of duplicated information
Not useful for Spatial Decision Making
It takes significant time and money to keep it up-dated
It is very hard to share the information among orga-nizations
Hard to Analyze from Overlapped Data

Geographic Information and Non-Geographic Information
Geographic Information and Non-Geographic Information
Geographical or Non-Geographical Data
Geographical or Non-Geographical Data
Is this subway “MAP” the Ge-ographical Data?
Location Data is needed (even Coordinate is not in-cluded)Attribute Data must linked with and based on Loca-tion
DAEGU CONTRIBUTED TO IMPROVEMENT OFGEOGRAPHIC INFORMATION SYSTEM IN KOREA
WHY?
KNU has hundreds of Geographical Experts
Students from KNU Geography are too smart
KNU just got highly trained foreign students
Tragic Events
Contribution of DAEGU to GIS, WHY?
Gas leakage and explosion at subway construction site in Sangin-dong, Daegu, on 28th April 1995
Disaster in 1995
Explosion Site
Dept. Store Con-struction Site
Gas Pipe Broken Site
Disaster in 1995
GIS became spotlighted as a means by which one can accurately identify and effectively manage underground facili-ties, following the tragic event; an ex-
plosion at a Daegu subway construction site which occurred in 1995.

Map is basic element for GIS as a Database
So, Remote Sensing is on the start line of GIS
Remote Sensing is one of the easiest way to make a map
Producing exact data is very important
Importance of Remote Sensing for GIS
The finished garment is dictated by the way the cloth is first cut
Importance of Remote Sensing for GIS
Can you measure how large the law school is?
By using Remote Sensing, It’s possible
Observing large Scale of Area at the same time
Monitoring usage of land is needed
Saving Time and money
Chasing Change of Land usage continu-ously
Updating Information easily
Usefulness of Remote Sensing for making Database
