HTML and CSS lego icons have a new friend : Javascript !

I was building my new courses in web development for Master SIGMA when I found some really nice illustrations explaining the role of HTML and CSS. But something was missing : Javascript ! I don’t manage to find the original author of these lego icons, but if you do, please comment.

Now, here’s the javascript animated lego icon :

Feel free to use it ūüôā If you need to mention someone : Nicolas Karasiak.

Get ROI values from raster and combine all CSV (remote sensing statistics with R)

R is a great tool for statistics, even if it may be slow in calculing raster’stats, it is really a good way for batching all of your work and presenting your data using MarkDown language. This example is one of my first autonomous script in R, and it is¬†very exciting for further. You can download the whole script SPOT5-GetROIvalues.R on GitHub.

Before showing you the different steps of the code, I need to present you the way I structured my data, because the script is going to parse them and to compile all tables in one file.

dzetsaka : how to make your first classification in Qgis ?

I just published the plugin dzetsaka : classification tool (github/qgis) on Qgis plugin server. This is a very simple plugin to make a fast but powerful classification. I used it for making numerous classifications of SPOT 5 scenes in the French Guiana Amazon forest.

A project with samples (an old map (map.tif) and ROI (train.shp)) is available on the docs branch. You can download these files directly here.

On Ubuntu everything works perfectly, but when I was trying on Windows I always had this error when loading the plugin “error enum : QgsMapLayer”. Read More

Making a modern map with an old style

A project with my teacher Laurent J√©gou was to design a recent map with an old map style. Some students chose to make the opposite, making an old map looks like a recent one (for example Rome in 300 A.D with an Open Street Map style).
I took the first project and I worked to make an actual map of Toulouse with an old style. I got most of my inspiration with the Rome map available on geotests (16mo).

How to split a gpx ? In each track, segment or trkpt ? (Python)

I had a project in my master’s degree (Sigma) to use python for doing something with a GPX file. There was a project like finding summit or pass, but I choose to edit a GPX to split it into in each of his tracks, segments, or by cutting the file into a specific point.

I choose to use LXML library to parse and edit .gpx, and OS to batch the process with multiple .gpx.
