PRODUCTGeoDT
• 2.2 (GIS Engine, C++)
• 3.0 ~ 5.0 (Intelli-CAD)
• Solutions
GeoDT Photo (PhoEMS)

PRODUCT
GeoDT 2.2
• Spatial Data Editing Tool with Built-in GIS Engine• Spatial Data Validation Tool
GeoDT 3.0 ~ 4.0
• IntelliCAD-based Spatial Data Editing Tool• Supports AutoCAD Lisp, Customization• Used for Editing KLIS Numerical Map
WHY?
Reason Why We Make Open Source Product
1. Construction of spatial data is the first step of NSDI
2. Secure reliability of the product
3. Globalization
4. Generalization
5. Contribution
NSDI
NSDI, We need..• Base Map• Network Infrastructure• Trained Professionals• Education• Standards• Etc..
Spatial Data Infrastructure is needed, but it costs too much.
NSDI
Construction of base map is im-portant at the first stage.
• Many developing countries which need NSDI have small population and large terri-tories.
• Needs help from ordinary people.• Communication technology is developed rapidly. (Internet and Smart Phone is popu-lar)
GOALS
• Easy to use• Web based system (GeoDT is C/S system)• Validating function by Officials(or Experts) for reliability of data
PROJECTS
OpenGDS / Builder
• Viewer/Editor
• GIS Engine
OpenGDS / QA (Quality Assurance tool)
• Validation tool
• Korea Cartography Standards (National Geography Insti-tute)
OpenGDS / DS (Distributed System)
• Distribute Processing Tool
OPENGDS/BUILDER
HTML5 based Web Viewer + Editor• Javascript, jQuery, AJax• 2D, 3D View and Edit• WebGL Rendering
Web GIS Engine• Built-in GIS Engine• Spring Framework• Support many Standards

And other modules…
OPENGDS/QA
Module of OpenGDS/Builder• Spring Framework based
Validates Data
Topology-based Spatial Operation
Provides Flexibility by Definition Files• Use XML Form Definition File
OPENGDS/DS
• To improve performance of OpenGDS/Builder
• Currently, research on distributed data collection is in progress.
