Lafayette Avenue, on the Fulton Street Subway, does not actually intersect Lafayette Avenue, though it is a just a short walk from Fulton Street, on the Lafayette Avenue Subway, just east of Fulton Street.

a really fucked up subway map. it's because Manhattan is not aligned north/south

I know there have been a lot of strong feelings about the new NYC subway diagram. I think I have found a new map layout that should make everyone happy.

Bellingcat’s New Tool to Explore Historical and Spatial Flight Data Turnstone can visualise historical trends in flight data or filter them by geography, aircraft type and other parameters.

Trying to make sense of an aircraft’s movements during a conflict? Context is everything. That’s why we built Turnstone, an open source tool that searches historical flight data to allow researchers to explore flight patterns over time and in specific locations. www.bellingcat.com/resources/20...

I do have to question whether it is the best use of municipal resources to have NYC DOT apply salt today. (38/34 degrees, raining)

the checklist ID S46116491 is entered, highlighting that user and their connections across the network

To find your own dot in the eBird network, you just need the ID of one your checklists (e.g. S46116491, which you can find from the URL of a checklist, ebird.org/checklist/S4...)

Then enter that ID into subject.space/projects-sta... and the visualization will show connections for that eBirder πŸͺΆ

The most connected birder on eBird (using the measure of "betweenness centrality") is none other than Chris Wood, Director of eBird at the Cornell Lab of Ornithology. ebird.org/profile/MTQ3... en.wikipedia.org/wiki/Between...

if you look at the model evolution, you can see why: it depends on accurately forecasting where the band of heavy precipitation will be. www.pivotalweather.com/model.php?m=...

the european model still has the heaviest snow more offshore, giving a much lower forecast for nyc.
