| The course "Introduction to Geoinformatics" is focused on presenting the foundational ideas of the discipline of Geoinformatics. We take a realist perspective, and ask ourselves the question: //What are the different types of geographical data, and how are these types representable in computers?//. | The course "Introduction to Geoinformatics" is focused on presenting the foundational ideas of the discipline of Geoinformatics.

| The beauty and the challenge of Geoinformatics is that there are a relatively small set of data structures that are able to represent different types of geographical data. This representational power has enabled software engineers to develop the technology of geographical information systems. The challenge is to understand both the data structures and the semantics of the information they represent. This course is then focused on discussing the semantics of geographical data, as well as the links between such semantics and the associated computer representation. When they complete the course, we expect that students should be able to understand the different types of geographical data and how they are represented in computers. | The beauty and the challenge of Geoinformatics is that there are a relatively small set of data structures that are able to represent different types of geographical data.

| - | === Motivation === | + | ==== Motivation ==== |
| - | The motivation for this course came from the need to establish a set of foundational concepts to the field of Geoinformatics. In recent years, there has been a significant contribution to this foundation from research published the world of Werner Kuhn, who published an important paper on "Core Concepts of Geographical Information Science". His idea is that there are some concepts need to be understood by all researchers and practitioners of Geoinformatics. | + | The motivation for this course came from the need to establish a set of foundational concepts to the field of Geoinformatics. To do this, we will examine reference papers published in the literature that are relevant to Geoinformatics researchers and practicioners. |
