50 Must-Follow Twitter Accounts for Geospatial, Data Science, and Visualization

Location Intelligence is a young field, forming at the intersection of new technologies and existing branches of knowledge. Twitter, a global sounding board for experts, is a natural fit for this growing sector and the perfect place to bring together collective expertise for greater development and collaboration.

To that end, we wanted to create a list of some of our favorite experts and organizations from several different categories:

Subscribe to the full list here!

Please note, this list is by no means exhaustive, rather it is a diverse sample of particularly active accounts that we love! In fact, most of the people and organizations listed below are fervent retweeters, and by following this list or the members of it, you will find not only their expertise and work, but also be quickly exposed to the wider community.

Additionally, while all of the below accounts are categorized, many of them transcend and blur these categorizations every day. We worked to fit these accounts in the section that we felt most matched their regular output.
