Shape file directory

It's a list from my perspective, I work mainly with geo data for Europe and Asian post Soviet Union countries. I wanted to keep all my sources in one place so I started this list, which I am planning to update when I find something interesting. I focus on open source shape files.

If you came across a website with shape files and you want to share it with me, it will be the happiest day of my life.

Велодорожки Москвы / Cycle lanes of Moscow

Портал открытых данных правительства Москвы опубликовал географические координаты московских велодорожек.
Общая длина велодорожек состоит 111 км. Самая длинная велодорожка находится в парке «Лосиный Остров».

Я хотела сделать карту поинтереснее и добавить другие данные к велосипедным геоданным, но не нашла ничего подходящего.

На моей карте можно включить Street View чтобы увидеть фотографии.

Reshaping data in Data Wrangler

Data Wrangler is a hero of this tutorial. It's free online tool to transform data.

There are three reasons why it's worth to use Data Wrangler:

• it's very easy to use
• although it's simple it offers many useful functions
• the app's done by nice people

The app has limitations, Wrangler only supports up to 40 columns and 1000 rows. If you are planning to work with something bigger than that, then you have to divide your data. This limitation is the most painful part of this tutorial so you can relax and keep reading, now there will be only positive things.

Something old, something new

I'm totally addicted to archaeological documentaries. My favourite archaeological site is Göbekli Tepe, google it, it's just WOW. In July 2014 Klaus Schmidt, who headed the excavations at the site, passed away. I started to thinking about doing something in this field. I wanted to analyse some data devoted to Göbekli Tepe, but I couldn't find anything. Archaeological data published in the internet are rarity.

How the world has changed from 1960, population comparator

I was playing with population data but I wanted to do something different so I took into account data for a long period.

I prepared population comparator, a tool to compare how the growth of population proceed in countries. Don't get wild and don't select too many countries as it will be impossible to see anything.
