<div dir="ltr"><p dir="ltr" style="font-family:arial,sans-serif;font-size:13px">Hi mates!</p><p dir="ltr" style="font-family:arial,sans-serif;font-size:13px">I’m Marco and I am working on the development of a tool to assess susceptibility of hydrologically controlled shallow landslides.<br>
The software will be based on the Ph.D. Thesis in Environmental Engineering by Lanni C. (2012) and will consist of a model available for use within the uDig/JGrass Spatial Toolbox</p><p dir="ltr" style="font-family:arial,sans-serif;font-size:13px">
These are the tasks I’ve been doing during this third week:</p><p dir="ltr" style="font-family:arial,sans-serif;font-size:13px">• What did I do this week?</p><p style="font-family:arial,sans-serif;font-size:13px">I still had to work on building the knowledge required to understand how to carry on the actual implementation.<br>
<span style="font-size:small">I used some of the introductory</span><span style="font-size:small"> resources pointed me by Riccardo Rigon: these lifted me to a better understanding of the domain than the one I had reached by directly reading the complex Lanni's Ph.D. Thesis.</span></p>

Since I could also get the hands on the "research code" written in R by Cristiano Lanni for testing the algorithm, I had to gather a minimum understanding of the S language to follow the procedures and to have his code running on my laptop. <br>
I used a couple of exhaustive resources (in Italian):</p><p style="font-family:arial,sans-serif;font-size:13px"><font face="arial, sans-serif">- Introduction to R: </font><a href="http://www.slideshare.net/SlidesIdrologia/9-introduzione-r" target="_blank">http://www.slideshare.net/SlidesIdrologia/9-introduzione-r</a> by <font face="arial, sans-serif">Riccardo Rigon and Matteo Dall’Amico<br>

<p style="font-family:arial,sans-serif;font-size:13px">Late in the week I could finally start reading and commenting the R script to match its routines with what stated in the reference paper(*)</p><p style="font-family:arial,sans-serif;font-size:13px">
<br></p><p dir="ltr" style="font-family:arial,sans-serif;font-size:13px">• What will I be working on next week?</p><p style="font-family:arial,sans-serif;font-size:13px">- I will keep studying the R code with the intent of splitting it in discrete sub-procedures.<br>
[Side note not relevant to GSoC but to my MSc Thesis: Lanni's code was clearly developed for research purposes with a trial-and-error approach. Due to this, it exhibits even to an absolute R-newbe like me, chances for improvement. I will discuss the interest of this with my University Tutor.]</p>
<p style="font-family:arial,sans-serif;font-size:13px">- Hopefully I will have enough time to start learning the basics of the JGrassTool framework so to be able to start the iterative design of the Spatial Toolbox Tool</p>
<p style="font-family:arial,sans-serif;font-size:13px"><br></p><p dir="ltr" style="font-family:arial,sans-serif;font-size:13px">• Did I meet with any stumbling blocks?</p><p style="font-family:arial,sans-serif;font-size:13px">
- Still the most complex task was (and still is) quickly gaining the needed hydrology background for understanding what I am doing.. ..but I feel that something is actually getting into my lazy brain ;-) For sure this helped making the job of managing R basics a comparatively trivial goal!</p>
