project documentation – part 1

My first open source project – Eliav’s wind rose

work documentation description

My First open source project “Eliav’s Wind Rose” started out as I needed to analyze wind data at my job as an environmental consultant.

I decided to build an open source application that will be easy to use.

The application is located on rstudio web servers at:, user instruction can be found here.

Another important aspect to my project (the hardest one apparently) is good documentation. So this here is my effort to document my work.

I will be happy to hear any comments.


1. Open source

“Free software means that the software’s users have freedom. (The issue is not about price.) “

(Taken from the “Philosophy of the GNU Project”(link))

i am a big fan of open source so it was clear to me that i want this project to be open, open in the way that it is freely distributed and work is in a community style

1.1 Availability of the code

The idea of this project is that the source code is published and made available on github (might be a little messy i am working on tidying it up), enabling anyone to copy, modify and redistribute the source code without paying royalties or fees.

I am new to github so even though it looks like there is a lot of ways to use it, right now i make use of github to store my code, and to look at different projects to get ideas.

1.2 community development

My aim is to keep building this through community cooperation.

from the beginning of this project I used many internet social tools like:

stackoverflow: stackoverflow is an enormous aggregation of geeks that will answer question I used stack overflow to ask technical questions during my work on the app

linkedin: I used linkedin groups like  ” Air Quality Dispersion Modeling ” and ” Air Pollution ” to get feedback on my app.

2. R

 I was introduced to R during my masters degree.

R is a programming language mainly used for statistical computing and graphics.

2.1 packages

The capabilities of R are extended through thousands of user-created packages 

 To build this app I used shiny a web Application Framework and openair a package for analyzing air pollution data

3. future planes

I  have a few ideas (theoretical more than practical) of feature i want to add to the app:

  • download the data as tables

  • add wind energy estimations(weibull analysis)

  • fit data to the different models

  • when i get the hang of using a web server i want to use my own instead of using the shiny hosting 

So i know i said it but i would realy love to hear and get ideas

Eliav’s wind Rose Instructions


So I wrote an appllication to analyze wind and air pollution data, this is the link to the app.

To write this app i used the R language, with two wonderful packages: shiny and openair.

Using the app:

  1. your wind data needs to be saved to a “csv”  file
  2. date column needs to be named date(lower case)
  3. the date format needs to be: ‘d/m/y H:M’
  4. go to the app web site:
  5. upload your data by pushing the button on the upper left side of the page
  6. choose your wind direction and wind speed columns using the drop down lists
  7. choose number of wind directions you want (the default is 12)
  8. choose sorting method using radio button

Later on I am planning on writing two more posts one technical including the code of the app and one theoretical.

I would love to hear any comment or idea’s to make this app better
