MASTER SPATIAL DATA ANALYSIS IN R & QGIS: HANDS ON TRAINING WITH A REAL SPATIAL DATA PROJECT!
Do you find GIS & Spatial Data books & manuals too vague, expensive & not practical and looking for a course that takes you by hand, teaches you all the concepts, and get you started on a real life project?
Or perhaps you want to save time and learn how to automate some of the most common GIS tasks?
I’m very excited you found my spatial data analysis course. My course provides a foundation to carry out PRACTICAL, real-life spatial data analysis tasks in popular and FREE software frameworks.
My name is MINERVA SINGH and i am an Oxford University MPhil (Geography and Environment) graduate. I am currently pursuing a PhD at Cambridge University (Tropical Ecology and Conservation). I have several years of experience in analyzing real life spatial data from different sources and producing publications for international peer reviewed journals.
In this course, actual spatial data from the Tam Dao National Park in Vietnam will be used to give a practical hands-on experience of working with real life spatial data and understanding what kind of questions spatial data can help us answer. The underlying motivation for the course is to ensure you can put spatial data analysis into practice today. Start analyzing spatial data for your own projects, whatever your skill level and IMPRESS your potential employers with an actual example of your spatial data analysis abilities.
This is a core course in spatial data analysis, i.e. we will focus on learning the most important and widely encountered spatial data analysis tasks in both R and QGIS
It is a practical, hands-on course, i.e. we will spend a tiny amount of time dealing with some of the theoretical concepts related to spatial data analysis. However, majority of the course will focus on working with the spatial data from the Tam Dao National Park, Vietnam. After each video you will learn a new concept or technique which you may apply to your own projects.
TAKE ACTION TODAY! I will personally support you and ensure your experience with this course is a success.

What is Spatial Data Analysis?
In this section the students are going to be introduced to spatial/geo-spatial data and how they differ from GIS. The students will then be introduced to the project they are going to work with, along with an introductions of the different questions they can answer through spatial data analysis. We will talk about the important applications of spatial data analysis, sources of free data and tools to be used in this course (R and QGIS). Briefly present the different softwares and packages that need to be installed.

Quick Introduction to Some Concepts Related to Spatial Data
This lecture will introduce some of the most common spatial data concepts that we will encounter most frequently. I will touch upon Coordinate reference systems and projections. I will also briefly introduce Raster data, vector data and point data

Conclusions to Section 1
In this lecture we will quickly reiterate the things we have learnt in the previous lectures. By now we have installed the both QGIS, R and the basic R packages needed for spatial data analysis. We are now familiar with terms such as latitude-longitude, coordinates and know the difference between raster and vector data. We are acquainted with our project study site and some of the questions spatial data analysis can help us answer. If we are all comfortable with this, its time for a quiz and next sections
