Prompted in part by a presentation I have to give tomorrow as an OU eLearning community session (I hope some folks turn up – the 90 minute session on Mashing Up the PLE – RSS edition is the only reason I’m going in…), and in part by Scott Leslie’s compelling programme for a similar duration Mashing Up your own PLE session (scene scetting here: Hunting the Wily “PLE”), I started having a tinker with using Google spreadsheets as for data table screenscraping.

Data Scraping Wikipedia with Google Spreadsheets

So here’s a quick summary of (part of) what I found I could do. The Google spreadsheet function =importHTML(“”,”table”,N) will scrape a table from an HTML web page into a Google spreadsheet. The URL of the target web page, and the target table element both need to be in double quotes. The number N identifies the N’th table in the page (counting starts at 0) as the target table for data scraping. Grab the URL, fire up a new Google spreadsheet, and satrt to enter the formula “=importHTML” into one of the cells: Many Eyes. OpenHeatMap. Playing with heat-mapping UK data on OpenHeatMap. Last night OpenHeatMap creator Pete Warden announced that the tool now allowed you to visualise UK data .

Playing with heat-mapping UK data on OpenHeatMap

I’ve been gleefully playing with the heat-mapping tool today and thought I’d share some pointers on visualising data on a map. This is not a tutorial for OpenHeatMap – Pete’s done a great job of that himself (video below) – but rather an outline of the steps to get some map-ready data in the first place. [youtube: 1. Find a dataset to visualise. You firstly need data that fits the geographical areas supported by OpenHeatMap (countries, constituencies, local authorities, districts and counties), and which suits geographical visualisation. My first stop was the data.gov.uk RSS feed to see what recent datasets had been released, but you could also do advanced searches for “unemployment by county” etc. if you are looking for something specific to visualise. Helpfully, each dataset description includes a field on “Geographical granularity”. Scraping for Journalism: A Guide for Collecting Data.

Scraping for Journalism: A Guide for Collecting Data

We’ve written a series of how-to guides explaining how we collected the data. Most of the techniques are within the ability of the moderately experienced programmer. The most difficult-to-scrape site was actually a previous Adobe Flash incarnation of Eli Lilly’s disclosure site. Lilly has since released their data in PDF format. These recipes may be most helpful to journalists who are trying to learn programming and already know the basics.
