About the Course
This course is organized into two parts presenting the theoretical and practical foundations of geographic information systems (GIS).
- Together theses courses constitute an introduction to GIS and require no prior knowledge.
- By following this introduction to GIS you will quickly acquire the basic knowledge required to create spatial databases and produce high-quality maps and cartographic representations.
- This is a practical course and is based on free, open-source software, including QGIS.
If you study or work in the fields of land management or the analysis of geographically distributed objects such as land use planning, biology, public health, ecology, or energy, then this course is for you!
In this first part of the course, we will focus on the digitization and the storage of geodata. In particular, you will learn:
- To characterize spatial objects and/or phenomena (territory modeling) with respect to their position in space (through coordinate systems, projections, and spatial relationships) and according to their intrinsic nature (object/vector mode vs. Image/raster mode);
- About the different means used to acquire spatial data; including direct measurement, georeferencing images, digitization, existing data source, etc.);
- About the different ways in which geodata can be stored - notably, files and relational databases;
- How to use data modeling tools to describe and create a spatial database;
- To query and analyze data using SQL, a common data manipulation language.
The second part of this course will focus on methods of spatial analysis and geodata representation. In this section, you will learn:
- How to describe and quantify the spatial properties of discrete variables, for example through spatial autocorrelation;
- To work with continuous variables. In particular, we will look at sampling strategies, how to construct contour lines and isovalue curves, and we will explore different interpolation methods;
- To use digital elevation models and create their derivative products (i.e. slope, orientation);
- How to evaluate the interaction between different types of geodata through overlay and interaction techniques;
- How to create effective maps based around the rules of graphic semiology;
- Finally, we will also explore other, increasingly common, forms of spatial representation such as interactive web-mapping and 3D representations.

this course helps me a lot in putting things I knew in the unprofessional or crude way into a more organized professional manner. if you are looking to learn the basis of GIS this is what you need

The content of the course is really good, I appreciate the effort of the teachers, however, the platform that marks the tests needs to be improved. Generally speaking, I have learned a lot with this course, albeit without a basic understanding of GIS.

This course is excellent regarding content and structure. However, it needs a bit more explanation of the QGIS software itself to facilitate the first part of the exercises and laboratories.

Very informative course on open source software like GIS and SQL. It was difficult to understand at first due to the language and translation in the slides but got a hang of it slowly.
