1.03 Exploring Geospatial Data

Here you will be introduce to ways of exploring Geospatial data for subsequent uses and more importantly meanings of certain elements in the Geospatial environment to help you in the fieldwork you will be undertaking as the beginning of the GIS course. Note that these concepts will be treated comprehensively in other topics of this course.

Here you will be introduced generally to what is called a "Model"? which means "to describe" or "to represent". This concept of a model will treated comprehensively in other topics.

Question

What are the key elements in exploration of Geospatial data for use?

Path

1. Model

The next concept you will be introduced to in this learning path is "Map" which is an example of a model containing spatial information.

2. Map

Here you will be introduced to what is "'GIS" which stands for Geographic Information System and is designed to capture, tore, analyze, manage and present all types of geographical data.

3. GIS

This learning path will introduce you to the term "System" which denotes the combination of parts that interact in order to produce a new quality.

4. System

It is now important to know how data is collected and various sources for data collection and this brings us to "Spatial Data Acquisition".

5. Spatial data acquisition

This learning path will introduce you to ways of storing and maintaining data collected for fit to use, hence "Data Storage and Maintenance" to be considered in details in other topics of the course.

6. Data storage and maintainance

In order to make sense out of data stored and maintained and give meaning to it and also provide new insights, this learning path introduces you to "Analysis".

7. Analysis

Last but least in this learning path that you will introduce is "Visualization" which helps us to translate spatial data from databases into graphics for users. This will be treated as a full- blow topic in the module 1.
