Information is getting more Important

What’s GIS

What’s GIS

What are needed for GIS? What’s GIS Obtaining valuable information Saving/Updating on the computer Analyzing the output or result to use information easier and useful Printing out the result Running hardware or software What are needed for GIS?

Problems of Classical Paper Map

Problems of Classical Paper Map WHAT’S NEW HERE? KNU GLOBAL PLAZA

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

Geographic Information and Non-Geographic Information

Geographic Information and Non-Geographic Information

Geographical or Non-Geographical Data

Is this subway “MAP” the Geographical Data? Geographical or Non-Geographical Data Is this subway “MAP” the Geographical Data? Location Data is needed (even Coordinate is not included) Attribute Data must linked with and based on Location

WHY? DAEGU CONTRIBUTED TO IMPROVEMENT OF GEOGRAPHIC INFORMATION SYSTEM IN KOREA WHY?

Contribution of DAEGU to GIS, WHY? KNU has hundreds of Geographical Experts Students from KNU Geography are too smart KNU just got highly trained foreign students Tragic Events

Disaster in 1995 Gas leakage and explosion at subway construction site in Sangin-dong, Daegu, on 28th April 1995

Dept. Store Construction Site Disaster in 1995 Gas Pipe Broken Site Dept. Store Construction Site Explosion Site

GIS became spotlighted as a means by which one can accurately identify and effectively manage underground facilities, following the tragic event; an explosion at a Daegu subway construction site which occurred in 1995.
