For my contribution to the big @GeogAnalysis 50th birthday bash, I reflected on how the geographical analysis/quantitative geography landscape appeared to me, a part of Generation 3.0, entering the field at a very particular time (and place) 9/n https://onlinelibrary.wiley.com/doi/10.1111/gean.12251#.YBwCN0wB6cU.twitter
Not gonna lie, these are some of my favorite words I've written in a long whileâI used the word "midwives" to characterize those who helped birth our field and even opened the paper with a quote from the Divine Comedy. Editors can have a little fun for a treat... 10/n
The very 1st paper to be accepted for the @GeogAnalysis 50th birthday SI was from @alexsingleton and @darribas on Geographic Data Scienceâa fantastic, must-read agenda-setting contribution on the various merits of engaging with data science 11/n https://onlinelibrary.wiley.com/doi/10.1111/gean.12194#.YBwFKoyTLLQ.twitter
The @GeogAnalysis 50th anniversary SI includes another agenda-setting paperâthis time on challenges and opportunities in geographical agent-based modelsâfrom @ajheppenstall, @AndyCrooks, @nickmalleson, @edthink, @bobogejiaqi & @jmichaelbatty. 12/n https://onlinelibrary.wiley.com/doi/10.1111/gean.12267#.YBwGsaq7nAw.twitter
We've got future directions in movement covered in this @GeogAnalysis 50th birthday special issue, as wellâin her contribution, @smayadodge calls for a revolution in how we visualize, model, and analyze movement. 13/n https://onlinelibrary.wiley.com/doi/10.1111/gean.12212#.YBwIHaOjcIw.twitter
The @GeogAnalysis 50th
issue is the gift that keeps on giving. From @lexcomber, Paul Harris, Lihe LĂŒ, Lianhai Wu & Peter Atkinson comes a thoughtful contribution on "what we do with spatial data"âthat is, the importance of model specification. 14/n https://onlinelibrary.wiley.com/doi/10.1111/gean.12199#.YBwoMULPyBs.twitter

Anchoring @GeogAnalysis firmly in 21st century analytical challenges, @pjkedron @amyefrazier @DrewTrgovac @TrisalynNelson & Stewart Fotheringham bring their A game to the 50th anniversary issue with their paper on reproducibility + replicability

Equally important for *all* geographical analysis is the societal impact of our research. In her contribution to the @GeogAnalysis 50th anniversary issue, @DrDelmelle emphasizes analytical opportunity alongside a call for research that matters. Amen. 16/n https://onlinelibrary.wiley.com/doi/10.1111/gean.12213#.YBwsZFd5P1I.twitter
Closing out the big birthday issue, David O'Sullivan reminds us that @GeogAnalysis is an "International Journal of Theoretical Geography" & exhorts us not to forget the theory. There's also a photo of a beach in this paper, which is surely a GA first. 17/n https://onlinelibrary.wiley.com/doi/10.1111/gean.12225#.YBwtb5ZpSSY.twitter
And that's it for the @GeogAnalysis 50th anniversary issue, which I've been working on for over 2 years.
Our field and our journal are no more dynamic that the people who are in it. So keep sending us your best geographical analysis research!!! And thank you!! 18/n
