Europe DbPedia 2017

europeflagdbpedia
I was kind of bored while doing some work, and just past week we were discussing with a colleague about my vague-places project.

This project was forgotten in time, but today I’ve blown the dust away, recovered it, and updated the Europe DbPedia map.

Most of you won’t be interested in the full story. So here, see a set of results. If something picks your interest (like, why Portugal has almost no points) just keep reading 😀

SLD in HTML and SVG

sld

A standard way to style any OGC layer is using SLD. Styled Layer Descriptors.

The Styled Layer Descriptors are a simple (and standard) way to style your web maps. But when you style you also want to generate a nice legend for it.

I recently found myself with the situation of reworking a website styling code. Instead of writing it from scratch we used existing pieces to cleanly fill our webapp divs with the correct legend.

Let’s style!

Retrieve KML links

kmlhell

On my previous post I worked with a kml that was splitted in various networked kmz files. This was particularly annoying given that I had to track the files in my computer.

I am ashamed, this should have been automatized! And since a friend prepared a nice script for it, here it is.

get my kmls

KML to DXF (hell)

kmlhell

The time goes by and I don’t have enough personal space to write in this blog. It is crazy how life changes and how many things are thrown at you.

That being said, recently I helped a friend with some format problems, and I thought it was a perfect excuse to prepare a new blog post.

come get some

Getting information from IPs

Posts come very slowly, but here’s another one.

This post won’t be useful for most people :-(. You know when you use google analytics and get that fantastic map showing where people connect from? Read this, and you will learn how to do it yourself.

Tell me how

Color to attribute. Qgis 2.X

qgis-logo-plugincolor

In 2012 I created a small plugin for Qgis1.x. It allowed you to modify a vector layer, creating a new column to hold the color of the features. This proved useful for me at the time. I could use Qgis to decide the color palettes and then export to wherever I wanted.

Come 2013, a new version of Qgis appeared, and the plugin broke. I wasn’t using it at the time and I didn’t realize it. But someone did, and kindly pointed me to the problem. I don’t have as much free time as I used to. However as my grandma used to say “better later than never”, here we have the plugin to work with the 2.x series!.

You can get it from my github. The master branch has the original code, and there is a new qgis2.0 branch with the new revamped plugin.

Salut!
