1. Package for Learning Fundamental Knowledge on Geospatial Technology Morishige Ota Fellow, Kokusai Kogyo Co., Ltd. Guest Researcher, The University of Tokyo Geosptail World Forum 2013, Rotterdam May 13-16, 2013

2. Outline 1.Background 2.Motivation 3.Experiences 4.Uniqueness 5.Gittok - geospatial information technology tool kit 6.Future works

3. Background World population growth depletes natural resources. Environmental issues and disasters are escalating. We need sharable geospatial data and Spatial Data Infrastructure (SDI) for decision making. We need people to maintain and improve SDI.

4. Motivation There are few software developed for the introduction to Geospatial Information Technology at least in Japan. The software learnable in short period designed on the basis of Geographic Information Standards are quite few, even they are basis of SDI and developed on the knowledge of Geospatial Technology

5. The project “GI Sciences Education and Spatial Thinking ” [Leader: Yasushi Asami, The University of Tokyo] 2009-2013. Experiences - Software Package Development Development of the software package for introductory course on GIT 2010 - Why I can challenge?

6. Experiences – Standardization Delegation member from Japan to ISO/TC 211 1995-2005 Spatial Schema, Temporal Schema, Rules for Application Schema, Moving Features, GML, … Project Leader for Japanese Industrial Standards. Since 2002- Temporal Schema, Metadata, and GML.

7. Experiences – GIT Body of Knowledge (BoK) The project “Development of geographic information science curricula and sustainable web library systems for serving their contents” [Leader: Atsuyuki Okabe, The University of Tokyo] The member of the research project investigating GIT Body of Knowledge 2005-2007

8. Experiences – The framework of GIT BoK Real world Modeling of the Real World Modeling of the Real World Model Formulation Spatial Analysis Spatial Data Acquisition Spatial Data Acquisition Spatial Data Management Spatial Data Management Spatial Data Service Spatial Data Service schema spatial index & operation result of query analysis methods interface Human Computer Interaction Human Computer Interaction Application of Spatial Information in our Society Application of Spatial Information in our Society spatial information model data structure specification spatial data service data The report of the research “Development of geographic information science curricula and sustainable web library systems for serving their contents” March, 2008

10. Uniqueness Gittok (geospatial information technology tool kit) is an introductory software for students who study GIT. Gittok is open and free. Gittok is implemented as Adobe AIR Application. Gittok complies with ideas behind of Geographic Information Standards. It is called “Jittoku Knife” in Japan. Jittoku means “ten virtues”.

11. Uniqueness – Ideas behind of GI Standards Design application schemas in compliance with General Feature Model Acquire and edit geo-data following the application schema and formulate them using Instance Model Encode and decode geo-data using XML Design maps using portrayal schema and dictionary “gittok” refers to a set of schemas simplified from GI Standards provided by ISO/TC 211.

12. Title page shows simplified framework of knowledge units in GIT BoK. Modeling Acquisition Management Analysis Exchange, and Representation (Human computer interaction). Users may start exercise by clicking icon which represents a knowledge unit.

13. Modeling: Application schema designing Feature Type Feature Attributes Feature Operations Association Type Association Attributes Association Operations

14. Acquisition: Feature instances and their attributes Adjustment between screen coordinate and plane rectangular coordinate Adjustment quality evaluation Digitize geometry Link to multimedia data

15. Acquisition: Association between features and attributes of association from to Association between different features Association Editor: Connector Association Editor: Attribute Editor

16. Management: Stand-alone clearinghouse and definition of CRS Describe metadataFind an appropriate kit Edit metadata Go to Acquisition Manager Go to Analyst Definition of Coordinate Reference System (CRS) video

17. Management: Definition of CRS (Coordinate Reference System) CRS Schema Screen coordinate Plane coordinate Lat. and lon. Affine Gauss-Kruger CRS parameters Typical projection system

18. Analysis: execute operations of feature and association Get the center position of the building (1) Open the kit (2) Select Building type (3) Select feature instance (4) Select operation and run it (5) Show ID of the point (6) Draw its position (1) (2) (3) (4) (5) (6)

19. Exchange: Encode and decode A part of encoded XML file. Coordinates are converted to decimal degree of lat. and lon. (4) (1) Select file for exchange (2) Select encode or decode. (3) Press start button (4) Select the file (5) Key-in the name of output file. Then, the file is stored in the folder. (1) (2) (3) (5)

20. Representation: Symbol, Label and Portrayal Design (1) Press Symbol Designer button. (2) Key-in the symbol name and select parameters (and digitize geometry in case of point symbol) (3) Press add button. (1) (2) (3) (2) (3) (2) (3) Symbol design LineArea Point Label design Portrayal Design Map Editing

21. Representation: Map Editing

22. Future works Implement, for example temporal attribute and improve map design mechanism Add English texts and manuals Release the alpha version as soon as possible And, I will try to give exercises for students in universities and in the GI-industry.
