Want to learn how to visualise and analyze spatial data in the social sciences and build your #GIS skills? My Intro QGIS and Advanced GIS courses are coming up, starting next week, with @instats instats.org/seminar/intr... instats.org/seminar/adva... nickbearman.github.io/training-cou... #GISchat

Hi data people, check out Exploropleth! exploropleth.github.io/exploropleth/. It's free, open source software that shows how binning methods affect maps. There's also a teaching worksheet and a journal article in CaGIS: exploropleth.github.io
@arpitnarechania.bsky.social &
@alexendert.bsky.social

Different maps that show life expectancy by county in the U.S., where the data is divided using different data binning methods.

Box plot style graphics show data points for adult percent obesity by county in the U.S.

New article! A fantastic new tool Exploropleth: exploratory analysis of data binning methods in choropleth maps, from @arpitnarechania.bsky.social Alex Endert & Clio Andris doi.org/10.1080/1523... #GISchat website exploropleth.github.io video of the tool in action: www.youtube.com/watch?v=lNV8...

Figure 5. Combine View lets users analyze a) a combination of one or more binning methods by visualizing b) the most consistent Bin,
c) the frequency of the most consistent Bin, and d) both together for each U.S. county in separate choropleths. The new, resiliency
binning method then utilizes this information to g) determine “resilient” bins (counts, intervals) that are also visualized in
a choropleth. Hovering any county on the map shows a tooltip with relevant information about the county, as shown in e) and f).

MapLayNet can learn a concept hierarchy of map layout via an unsupervised data similarity measure. The resulting layout embedding can be further explored for more cartographic tasks.

The Cartography and Geographic Information Society @carto-giscience.bsky.social · Aug 26

New paper from Jian Yang and colleagues, presenting MapLayNet, a way of understanding maps as a graph and classifying how they are laid out, with the aim of better map layout retrieval and design recommendation #GISchat #OpenAccess doi.org/10.1080/1523...

Figure 1
Research diagram illustrating map layout graph construction. Part a) shows a world map of seismic activity with 6 colored markers representing different elements on the map. Part b) transforms these into a graph theory representation where elements become vertices (v1-v6) connected by edges showing relationships.

Figure 10
Machine learning visualization showing how AI clusters similar map elements together. Each dot represents a different map and are grouped together in 2D space according to their layout. The algorithm successfully identifies layout patterns across different map types! #MachineLearning #Cartography

Great new article! Victor Irekponor & Taylor M. Oshan
address reproducibility in spatially varying coefficient (SVC) models, and introduce svc-viz, a open source Python tool to-do this #GISchat doi.org/10.1080/1523... github.com/marquisvicto...

A three-panel visualization showing bandwidth selection and spatial analysis for local intercept estimation. The top panel displays an AICc curve starting around 2000 at spatial unit 0, dipping to a minimum near bandwidth 220 (marked by a green vertical line), with an orange dashed line indicating another reference point, then rising steadily to about 5000 at spatial unit 3000. The middle panel shows a choropleth map of the contiguous United States with counties colored on a diverging red-to-blue scale, where darker red regions (values around -2) appear concentrated in the Southwest, particularly Texas and surrounding areas, lighter colors (near 0) cover much of the central and eastern US, and blue regions (positive values up to 4) appear in the Pacific Northwest and parts of the Northeast. The bottom panel presents a caterpillar plot showing coefficient estimates with confidence intervals across approximately 3000 spatial units, displayed as vertical bars in gray and colored segments (red for negative, blue for positive values), with most estimates clustering near zero but showing notable variation and wider intervals toward the right side of the plot.

Great new article from Michala A. Garrison, Schyler A. Reis, Shiyu Zhang and Carolyn S. Fish, evaluating “narrative transportation” – how engrossed one becomes in a story when used in storytelling maps, and the impact of including maps and photos doi.org/10.1080/1523... #GISchat

Alternative options in the survey, including low or high narrative text, and the addition of maps and photos.

New Paper! Yuanfang Chen and colleagues present a new way of contact-tracing, the PSTP-STRA method doi.org/10.1080/1523... #GISchat

This map shows spatiotemporal risk values for two villages (Xiaoguo village and Liujia Zuo village) as of January 6, 2021. The risk values are displayed using a color-coded legend ranging from 0 (white) to 6-24 (red), with intermediate categories of 0-2 (light gray), 2-4 (light blue), and 4-6 (orange).

The map displays various geometric shapes and structures scattered across the area, with the highest risk concentrations (shown in red and orange) appearing to be concentrated around the central area between the two villages. Lower risk areas are shown in lighter colors.

Saw a post from an influencer telling followers to "stop using R for anything -- use Python like a normal person"

As a 10+ year R & Python user, the irony is that 2025 is the best time EVER to be using R.

Here's why:
