Yesterday, Google launched their Maps Engine Lite beta; a way of quickly and easily visualising small scale geographic data sets on (unsurprisingly) a Google map. The service allows you to upload a CSV file containing geographic information and style the resulting map with the data added to it. I thought I'd give it a try.

I turned to my tried and trusted data set for things like this; a data set I derived from a Flickr set of geotagged photos I'd taken of the London Elephant Parade in 2010. It's a known data source and I know what the results of this data set will give me; it lets me do a reasonably meaningful visual comparison of how a particular product or service interprets and displays the data.

This is another mass transit map, but this time it's not of the London Underground system, but the U-Bahn and S-Bahn system in Berlin. The name U-Bahn derives from Untergrundbahn, or underground railway whilst S-Bahn comes from Stadtschnellbahn, or fast city train.

As a general rule of thumb, the London Underground is, as the name suggests, underground in the centre of the city and surfaces as you move into the suburbs. The same can't be said of the U-Bahn and S-Bahn, which is underground and overground in pretty much equal measures over a lot of the network.

But this post is not about the official map of Berlin's transport, it's about this, unofficial, map of Berlin's underground and not so underground trains.

These days there's so many ways that you can make a map. You can use a Javascript Maps API and put push pins on a slippy map. You can take vector data, transform it into JSON and use a different Javascript API to make an SVG map. You can load data from pretty much any source into either a desktop GIS or a visualisation tool. The possibilities are endless; maybe more endless than you might first assume.

Thierry Gregorius has helpfully put together a cut out and keep guide to which type of mapper you are.

Like most people, my email Inbox gets hit with a lot of spam on a daily basis. Most of this is caught by my email client's junk mail filtering, but some gets through. Most of it is, at face value, auto generated; phishing attempts for bank accounts I don't have or solicitations for advance fee fraud.

But there's also been a recent spike in people wanting me to embed infographics or links into one of my sites that the sender thinks my readers might like. Most of these are so off target as to be ignored, but sometimes there's a mail that seems to have come from a human and might even be relevant to what I write about, but that just fails on so many levels. This is one such email, redacted to save the originating sender and company from any embarrassment.
