Dynamic World Landcover

Good article reviewing the Dynamic World Landcover dataset from WRI and Google Earth.

GeoTech

Data Visualization and Stacked Maps

Interesting application of indoor map tracking with a use case of wheelchairs at airports, viewed in multiple levels of the airport indoor map.

CyArk

CyArk is always a good way to while away some time exploring cultural sites in 3D. In this link you can explorer Lamanai Mayan temple in Belize.

BioGeography

We need a new name for the study of Genetics and BioGeography. Genetic analysis is a tool that is fast growing and being widely adopted in many disciplines and I love it when it ties into Geography. Here’s an example on the spread of the German Cockroach.

Results from Tang and coworkers (2024) showing the genetic structure of German cockroaches and possible migration pathways. Populations of B. germanica in China and island southeast Asia did not originate in Europe but instead came from south/southeast Asian sources around the same time that European populations first emerged.

Better technology tightens the dates for Vikings in North America at the L’Anse aux Meadows archaeological site.

Vintage US Topos

Nice post from John Nelson on the latest way to view vintage US Topo Maps. Great way to get lost browsing your favorite places.

PNW

The Rise of Hate. Great story in HCN about the history of hate in Western Washington and it’s history rippling in and out from the rest of America. I did not know the American Legion had it’s roots in White Nationalism. In my mind it is history rhyming with powerful interests influencing the ignorant to the detriment of the human condition. Back then it was anti-union timber barons, right now it’s Rupert and Zuck, rhyming on and selling fear, because fear sells. There can’t be an “Us” if you don’t demonize “Them”.
