Finding data just became easier with Google Dataset Search
Finding data is not easy. Let’s say you’re working on a data visualization project and you have a rough idea of what you want to create, but you’re not sure where to find data, or what data to even use. We provide some sample datasets to help you get started visualizing data with Tableau Public, and there are some additional data sources listed in previous blog posts “Data sources you need right now” and "Roundup of Tableau Public's Data in the Wild Sources." That’s not to say your data exploration journey has to stop there. There are many other places that may have the dataset you’re searching for:
- Data is Plural
- UN Data
- World Fact Book
- UN Environmental Data Explorer
- World Health Organization
- Pitney Bowes
Google Dataset Search
In addition to the data sources mentioned above, Google recently launched a service that will help you in your search for data. Google Dataset Search enables easy access to many thousands of data repositories on the web. According to Natasha Noy, a Research Scientist at Google AI, Dataset Search was created for “scientists, data journalists, data geeks, or anyone else [to] find the data required for their work and their stories, or simply to satisfy their intellectual curiosity.”
How it works
It’s very simple. Open Dataset Search, enter what you’re looking for, and Dataset Search will guide you to the published dataset on the repository provider’s site. The results shown are datasets published using schema.org standards. It works in multiple languages with support for additional languages coming soon. You can learn more about the technology and how it works on Google’s blog and developer's site.
Google Dataset Search is great if you are browsing for data on a topic, or you aren't exactly sure what data you need. However, if you know exactly the data you are looking for, there's potential that you will come across data that doesn't exactly fit what you need. Maybe the data is not the right size, time duration, shape, or level of detail, in which case you may need to keep looking or create a dataset on your own. Google Dataset Search doesn't currently give users the ability to search for datasets based on different parameters, but this would be a very useful feature if developed.
Let’s say you were looking for data for Iron Viz: Water. If you weren’t sure where to start or what data is available on the topic, just search for “water” in Dataset Search and you will quickly see a wide variety of results, spanning across many different websites. Click on any result to see a brief description and a link if you’d like to learn more about the data.
I downloaded "Water Capture by Method" by the City of Los Angeles from Kaggle and made a viz to learn a little more about water capture and rainfall in Los Angeles.
