Background of this project
3
User friendly
Map sheets based download
Products based download
Ready-to-use
Need to do additional job for the users purpose.
Format, CRS conversion, layer extraction…
Up-to-dated
Seems very slow update cycle, that’s not true though.
Concurrency issue between map products.
è What are the main reasons of this dissatisfactions?
Voice of customers
To meet customers’ needs, NGII looks into different approach
With current system, hard to meet various customer needs
Customers want ‘ready to use’ products
Low customer satisfaction
4
Background
Too many products(Topo, TileMap, GeoPDF…)
Too many scales(1K, 5K, 10K, 25K…)
Map sheets based update and managing
Many resources are required to maintain & produce various maps
Hard to utilize old data

Toward mass customization
User friendly mindset
<Present> <Future>
1. Customers want more personalized products2. New flexible system is required to meet customer needs
So, what should we do next?
What is mass customization?
What is Mass Customization?
… is a technique to produce customized products at lower cost associated with mass production. “ ”
Mass Customization = Mass Production + Customization

è What’s difference between McDonald’s and Subway?

When you visit McDonald’s…
“1 big mac, 1 chips and coke please”

Geospatial Mass Customization
“ ”15
… is a system to produce customized G.I. to meet customers personalized needs at geospatial object level.
è From pre-produced map to on-demand geo-information
Geospatial mass customization?
Variety of Customer Needs1
Customer’s Higher Expectation2
Fast Changing IT Environment3

To meet and respond to
for the overall efficiency and customer satisfaction.
Why we need geospatial mass customization?
• Traditional paper map • Cartographic representation is very importantPaper Map
• Digitalized paper map • Managed just like paper map(map no, sheets…)• File based
Digital Map
• Seamless digital map covering whole Korea• Layer by layer management• Still Map publishing concept
SeamlessDigital Map
• Geospatial object based management • Time series management of all the geospatial object• No more map concept

è From file based to DB based
Need to change data flow…
20
Data updating policy can be changed…
Present
1. Product(Map) centric
2. Release whole coverage
3. Periodic regular update as main source
4. Occasional update as supplement
5. Seamless digital map as master DB
6. Coverage based versioning
Future
1. Geospatial object(layer) centric
2. Release changed objects
3. Occasional update as main source
4. Periodic update as supplement
5. Framework data as master DB
6. Object based versioning

2 Main Components of Pilot System
1 Spatial object versioning system - Who edited when and what?- Store only changed object information- Could manage time-series data - Object based management- Base system for fast updating
1. Improve quality 2. Meet various needs flexibly3. Detect change object by object
2 Mass customization service system- Provide object centric information- Can select time, format, coordinate system
based on users requests- Provide data only users want- Provide data with styling file
1. Provide ‘ready-to-use’ data2. Provide customized data3. Increase visibility of data
27
Spatial object versioning system
• Could detect changed objects very easily• Could rollback to specific time• Could service objects at different time through OGC standard
