Back after a few years and excited to break the silence with our latest research! We (@ckuejio) dive into the extent to which, and for whom, differential privacy skews life expectancy estimates for census tracts in Florida. Check it out: https://t.co/xdET7uP1Tk

3/ However, as is often the case, study areas have irregular, large-sized polygons with a sparsely distributed population. In such cases, the geographic centroids and population-based centroids will produce different outcomes regarding accessibility values and spatial disparities

[Kyusik Kim @kyusik_]

Do you have a reason for using population-weighted centroids when measuring spatial accessibility? Find the reason in this article: https://t.co/dlqiSkbbVa

The new article provides evidence as to why population-weighted centroids should be used over geographic centroids.

2/ If your study area consists of regular, small-sized polygons that are densely populated, accessibility values using geographic centroids will be similar to those using population-based centroids.

Happy to share my recent article published in the Annals of @theAAG. This paper introduces GeoShapley as a method for measuring spatial/location effects in machine learning models. Open access: https://t.co/70JFZLBzJY. @FSU_Geography

Analyzing the "catchment areas" around facilities is a critical topic in spatial data science.

How you define a catchment area can matter a lot. Should you use distance, or should you use travel-times?

@liuluyu0378 Oh oh… I missed this…😢

[Kyusik Kim @kyusik_]

I arrived at #TRBAM! I will be presenting Exploring the Life and Trip Satisfaction of Extreme Commuters in 150B Convention Center tomorrow (Jan 8) from 3:45 PM to 5:30 PM. If you are interested, please join us!

[Kyusik Kim @kyusik_]

looking forward to it!

👀What just dropped on my desk! Hope the title is obvious enough to tell what it is about. @TaylorOshan @FSU_Geography @umdgeography @ASU_SGSUP @CRCPress https://t.co/gDJftVzuor

Lol who did this

[Kyusik Kim @kyusik_]

@liuluyu0378 Congrats!! Welcome to Florida :)

[Milto Miltiadou (She) @DrMiltiadou]

Seems like an interesting tutorial to learn how to process Geospatial data in Python!!

What methods are commonly used to measure transport inequality & poverty? What are their limitations, and which alternative methods can help us advance transportation equity research & policy? @AlexKarner @FarberSteven & I have a new preprint on this. https://t.co/uAyUGaXADX🧵

Excited! 🎉🥳

Dr. Mark Horner was honored at #AAG2023 with the Edward L. Ullman Award for his contributions in the field of Transportation Geography. As an honoree, Dr. Horner will give the Fleming Lecture at #AAG2024.

Congrats!

@liuluyu0378 Congrats Dr. Liu!! 🎉

[Rafael H. M. Pereira 🚡 Urban Demographics @UrbanDemog]

Super glad to share the English version of our on-line book to teach urban accessibility and data analysis with a hands-on approach in R #rstats.

Dr. Mark Horner, Professor of Geography at Florida State University (@FSU_Geography) where he has served on the faculty since 2004.
Congrats Mark!

[Steven Farber @FarberSteven]

I am very happy to share the schedule for the eleven incredible #TransportJustice sessions we put together for @theAAG and @AAG_TGSG. Thanks to the incredible group of students and colleagues who put this "mini-conference" together! I can't wait! Please RT.
