Pre Recorded
Using a combination of lectures, coding exercises in R, and case studies, participants will learn to:
The course is entirely R-based and while techniques of working with spatial data in R will be covered in detail, prior experience with R is highly recommended. If you are new to R, this course will be of most use to you if you work through a few tutorials to understand the basics of R programming before the start of the course. Students are highly encouraged to bring their own data sets, but this is not required for participation.
Course material will be presented by Matt Fitzpatrick who has published broadly in the use of SDMs for applied and basic science.
Any researchers (PhD and MSc students, postdocs, primary investigators) and management and environmental professionals in government and industry interested in the use of SDMs for conservation, biogeography, spatial ecology, or related disciplines.
Last Up-Dated – 05:05:2023
Duration – Approx. 32 hours
ECT’s – Equal to 3 ECT’s
Language – English
There will be a combination of lectures and hands-on practicals. Afternoon practicals will be based on the topics covered in the morning lectures. Data sets for computer practicals will be provided, but participants are highly encouraged to bring their own data.
Familiarity with GIS and geospatial data (i.e., rasters and point occurrence data). A basic understanding of statistical modeling concepts and inference, including regression methods and model validation.
Basic proficiency with R, including an ability to import/export and manipulate tabular data, fit basic statistical models, and generate simple exploratory and diagnostic plots.
A laptop computer with a working version of R or RStudio is required. R and RStudio are both available as free and open source software for PCs, Macs, and Linux computers. R may be downloaded by following the links here https://www.r-project.org/. RStudio may be downloaded by following the links here: https://www.rstudio.com/.
All the R packages that we will use in this course will be possible to download and install during the workshop itself as and when they are needed, and a full list of required packages will be made available to all attendees prior to the course.
A working webcam is desirable for enhanced interactivity during the live sessions, we encourage attendees to keep their cameras on during live zoom sessions.
Although not strictly required, using a large monitor or preferably even a second monitor will improve he learning experience
