Introduction
Research project has been conducted under the framework of the KUTKM Research Grant and e Science Fund.
GIS within last few decades, GIS has been proved as “a powerful research tool” to provide timely predefined information.

What is the Problem with the issue of
lack of Interoperability?
Why shouldn’t different GIS users share or collect …..
Spatial data acquisition : Costly Re-digitalizes data: Precision
and accuracy, editing spatial data is problematic
Import, export and conversion: Loosing to much information
GIS interoperability problems
Many GIS users using different GIS platforms and advancement in Internet technology can not be fully utilized due to lack of interoperability.
There is still “lack of perfect union” between the functionality of two more different GIS platforms.
Even using same platform also rises up similar problem “due to differences” in the conceptual data models, semantic meaning, data collection scheme and quality of parameters used.
GIS Interoperability Problems…con’t
Reveal the needs of interoperability, between two or more different GIS platforms.

Concept of Interoperability at Concept of Interoperability at application levelapplication level
The spatial information sharing or interoperability is referred to inter-application process control within distributed collection of different platform GIS users, data, software, and hardware.
GIS Interoperability Modules
Module 1: User Focusing on the technical aspect of achieving
interoperability such as protocol, semantic translator, file format and technical solution used
Module 2 : Resources Discovery Server moduleMetadata format, vocabulary use and semantic dictionary
Module 3: GIS service provider Address organizational and operational aspect Agreement of data exchange, Rule for data access and Rule of data

Metadata
Data about data Gained trust from user as indexing
tools particularly since the advent of large scale repositories on Internet.
Provide important background information about dataset such as What it is Where and where it was compiled Who collect the information
Conclusions related to systems
interoperability Each service provider or data owners
such as government, commercial entities, educational institutes, news organization and general public has to register (publish) by means of metadata to the catalogue to permit accessibility.
Conclusions related to RDS
Database engine Simplify the process of application
connection. Concern on data access among different
places and time. RDS employs clients to DBMS server
architecture to facilitate cross platform communication to the server from client side driver.
