This page collects together all of the “experiences” associated with individual modules.
+
+
In this site, experiences represent “active” learning opportunities, as opposed to readings, which represent “passive” learning opportunities. In many courses, readings and experiences together constitute the “assignments”.
The Geoinformation Systems course is a full term overview of selected topics in advanced GIS analysis as reproducible research workflows, based on R and Open Source Software and a full integration of GitHub.
+
+
Who should take this course
+
+
This course is intended for the master level in Geography to participants who have a working knowledge of the basic organisation of there operating system.
+
+
Didactical concept
+
+
LV-19-d19-006 is structured as a sequential but not necessary linear series of modules, each taking approximately two weeks to complete. Each module has the following internal structure:
+
+
+
Prerequisites - basic skills you should have prior the module/course start.

+ *
+ * Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
+ *
+ * Solution:
+ *
+ * We assume the radius of the polygon is half the size of the canvas at first
+ * at each index we check if the text overlaps.
+ *
+ * Where it does, we store that angle and that index.
+ *
+ * After finding the largest index and angle we calculate how much we need to remove
+ * from the shape radius to move the point inwards by that x.
+ *
+ * We average the left and right distances to get the maximum shape radius that can fit in the box
+ * along with labels.
+ *
+ * Once we have that, we can find the centre point for the chart, by taking the x text protrusion
+ * on each side, removing that from the size, halving it and adding the left x protrusion width.
+ *
+ * This will mean we have a shape fitted to the canvas, as large as it can be with the labels
+ * and position it in the most space efficient manner

2. Reproducible Research
+
The importance of reproducible research lies in the reproducibility of research results - i.e. the ability to repeat experimental procedures and thus confirm previously obtained results - this is the central element of scientific work.
Suppose the research question we are concerned with is as follows: Is it possible to derive a suitable set of predictor variables from LiDAR data to obtain a reliable prediction of the microclimate parameters temperature and humidity?
+
+
+
Task: - Read the ressources related to forest and identify those which you will use for attempting the task. - Decide which algorithms and indices are adequate to answer the research question - Apply and document this findings with on base of the scripts of the this unit experiences
+
+
+
Note:
+ You will find backgounds under the module Reproducible Research that will guide you in the creation of scientific research.
+ For this task please follow the instructions you will find at Academic wiriting made easy.
+
+
+
Important: Don’t forget to create a Github repo and invite your instructor!
+
Note:
+ It would be very beneficial if you could get a solid overview of all the foundations chapters. What does that mean? At least you should have in mind for arising questions that there are solution examples.
+
+
+
Note:
+
+You might find it helpful to document your learning progress and experiences in a portfolio.Support is provided by the module Reproducible Research It provides some entry points for documenting and structuring inquiry-based learning and work.
+ For this task you might follow the instructions you will find at Academic wiriting made easy.
+
+
+
For this time no upload of the exercises has to be done.
+
Here you find an appetizer. Work your way through the foundations and start with phic data
+and are important and should be at least cross-read and present. Geographic Data in R. Also the chapters Geographic data in R, Attribute data operations, Spatial data operations, Geometry operations, Reprojecting geogra.
The chapter Geographic Data IO is of course of elementary importance for the entire reading and writing out of data and should be worked through in any case. .

Welcome to LV-19-d19-006 - GIS, Winter 2021
+
+
The Geoinformation Systems course is a full term overview of selected topics in advanced GIS analysis as reproducible research workflows, based on R and Open Source Software and a full integration of GitHub.
+
+
Who should take this course
+
+
This course is intended for the master level in Geography to participants who have a working knowledge of the basic organisation of there operating system.
+
+
Didactical concept
+
+
LV-19-d19-006 is structured as a sequential but not necessary linear series of modules, each taking approximately two weeks to complete. Each module has the following internal structure:
+
+
+
Prerequisites - basic skills you should have prior the module/course start.
The responsibility for the content rests with the instructors. Statements, opinions and/or conclusions are the ones from the instructors and do not necessarily reflect the opinion of the representatives of the University of Marburg.

Step by Step instructions setting up your workbench
+
+
To set up a working or project environment, (normally) the first steps are defining different folder paths and loading the necessary R packages as well as additional functions.
+
+
If you also need to access additional software, like GIS, the appropriate binaries and software environments must be linked, too. Factoring in the major operating systems and the potentially multiple versions of software installed on a single system results in almost unlimited combinations of set ups.

You also able to structure your report in a meaningful way
A Markdown editor is an intuitive and low-threshold text editing tool.
+The goal is to create content with a few formatting instructions that are set as tags in the text, so that it is easy to read and at the same time has an appealing and elaborate layout. Furthermore, the Markdown format allows the arbitrary creation of all common output formats. Text can be translated into web-based, electronically published or conventional print-based output formats. Especially for efficient and appealing communication on the web and the generation of well readable print texts it is an ingenious little helper.

+
Markdown Editors
+
+
RStudio
+
Before the course background - r-spatial- is the preferred “editor” RStudio. It offers all functionalities for Markdown and additionally RMarkdown to automatically integrate evaluations scripts and images. at the same time it is directly connectable to github and from my point of view the best tool for such a combined way of working.
+
+
Online Editors
+
Most recomended for occasional use are online Markdown editors. My personal ranking:
In addition you find OS specific desktop applications. Most of them are platform independent .However they have speific OS-related pros and cons. So you will find two recommended editors per platform - just have a try.
