2. Overview
Introduction
Classical Fieldwork
Geospatial Data and Its Application
New Communication, Internet
Implementation
Internet Data Stream(Server-Client)
Using Java and database conectivity
MsqlJava and IGDS
Application
Case study area: Tertiary deposits of Korea
Construction of field database
Avaliablity, Limit and Suggestion

3. INTRODUCTION

4. Classical Fieldwork and Now(1)
Methods in field
Mapping to tophographic map immediately
Write down outcrop information to fieldnote
Rearrangement of data, another room research

5. Classical Fieldwork and Now(2)
New current
Desktop Softwares and GIS database
Fieldlog: AutoCad & GSC
GSMACD: USGS Mapping tool
ArcView, ArcInfo: ESRI
Laptop field-data system: FIELDTOOL of KIGAM

7. Basic idea of IGDS
Outcrop/Field
- Easy, factly and avaliable
- Graphic user interfaced
communication method
Internet
- Modem connection
- Use slip/ppp protocol
- Realtime data transferring
and processing Laboratory

8. IMPLEMENTATION

HTTPD CGI
HTML mSQL
Applet Viewer Database

10. Java(1)
Overview - What is Java ( http://java.sun.com)
New, general purpose object-oriented
programming language from Sun Microsystems
Allows users to interact with Web pages simply
Allows interaction with program running as an
extension to your Web browser
May be used for writing both network-oriented
and local application programs
It's Simple, Object Oriented, Secure,
Portable, Fast (potentially) and Multi-
threaded

11. Java(2)
Why Java to geologic data?
HTML is statical and impossible of inputting
multi-points and area selecting as like field data.
Java can solve them!
Java is platform-independent, object-oriented, easy
to learn and access to network in field area
Java fits this conditions for re-engineering the
geospacial broswer to receive dynamic data
Java is proper to coding and running in
network environment to offer pre-
programmed geologic database and software

12. Mini SQL Server
Mini SQL 2.0 is good small database
system and freeware
Designed to provide high speed access to small
data sets
Based on UNIX workstation
Software has proven to be popular on Internet
Many contributions for mSQL, especially
internet, mSQL-CGI, Java etc.

13. MsqlJava
MsqlJava is a Java class library mSQL
database
Client for mini-SQL (mSQL) database server
Written entirely in Java
Released early November 1995
MsqlJava based on JDBC:
SUN's ODBC for Java
Wrapper for mSQL-Java developed by George
Reese
Developed by Darryl Collins
