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
