Data Model and Data Processing
Steve Ramroop, Ph.D.
Course Outline
This is a five hour online course that discusses the basic database approach adopted over the years in GIS. The five data models are described and explained in the context of GIS implementation. Of the five database models the most popular model is identified. Topics of the course are: data models; data structures characteristics, their creation and storage methods; and a set of common GIS analyzing capabilities of all GIS software.
This course includes
a multiple choice quiz at the end, which is designed to enhance the understanding
of the course materials.
Learning Objective
At the conclusion of this course, the student will:
- Be able to understand the various database approach adopted over the development of GIS;
- Understand the importance and the know how of defining a data model;
- Relate the importance of having data layers in order to do any GIS analysis;
- Recognize the various data models adopted over the development of GIS;
- Be able to understand the basic data structures used GIS application;
- Define the characteristics of the data structures used in GIS;
- Recognize the various methods of creating data structures in GIS;
- Define the methods of storing the various data structures in GIS;
- Compare and make recommendations of suitable data structure;
- Understand be able to define topology;
- Define topology using the different data structures;
- Recognize and understand some of the common analyzing capabilities in GIS;
- Describe the need to be selective in choosing suitable data sets for a GIS;
- Recognized that the importance of having a DBMS in any GIS implementation; and
- Recognized that data sets need to be organized before they can be collectively analyzed.

Course Summary
GIS is a fast developing technology that has filtered into many professions. Some use of the GIS is far advanced while other uses are in its infancy stages. This course is one in the series of courses that presents some of the basic of the data models, data structures, data management, and data processing techniques adopted in a Geographic Information System (GIS). In any GIS implementation these are critical considerations before attempting any GIS application development.
