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

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.
