From {tidycensus} creator Kyle Walker: “My webinar Analyzing 2020 Decennial US Census Data in #rstats is now on YouTube!
In the 3-hour webinar, you'll learn about:
📈 Available datasets in the 2020 US Census, and how to access and use them in R;
📈 How to explore decennial US Census data with tidyverse tools;
📈 Using interactive maps to explore US Census data;
📈 Advanced topics like working with detailed DHC-A data and analyzing change over time“ 1/2
From {tidycensus} creator Kyle Walker cont.: “All the webinar resources are available on GitHub here, along with a @Posit Cloud link where you can run the code without installing R yourselves:” 2/2
Today's fun/success: managed to whip together some software in a few hours on Friday to map out the path of the eclipse totality in real time, and it worked today! I guess I can use it again in 2044, LOL. #software#gis#mapping
Is there a Google Earth-equivalent open source software? Anyone? Maybe something that at least takes in open street map data and let's you put pins and stuff.
Needs to work offline, I'd like satellite image data but need topographic data.
Asking for #HamRadio reasons, I guess I could try tagging #gis
I just learnt that the buffer tool radius in QGIS depends heavily on the projection. And also how easy it is to reproject a layer – just export it! That shifted a purported 800 metres to pretty much exactly the 1000 metres that I'd asked for.
It has been so long since I took the ArcGIS University courses (which I found not that great; perhaps they're better now) that I'm re-learning things that I didn't even know I'd forgotten.
We make the Agroecology Map data available in GeoJSON format so that you can use it in your analyses. You can now export all data and use it under the Creative Commons 4.0 (BY-NC-SA 4.0) license.
See how easy it is to use the Agroecology Map data in the QGIS tool

I've created a new web app - British Placename Mapper at https://placenames.rtwilson.com/ - you can search for placenames in various ways (starts with 'great', ends with 'burgh' etc) and show them on an interactive map. Try a few of the examples and send me any cool maps you come up with!
(Re-posting for those who sensibly weren't using social media on a bank holiday weekend!)
Ever wondered about UK place names? My new web app lets you search place names (starting with 'south', ending with 'burgh', containing 'sea' etc) and plot them on a map - and then share those maps with friends.
Oh look! I have a pre-Google map of Sunnyvale! Look at that giant undeveloped land at Wolfe and Homestead! Maybe someday someone will put a duck pond there. Can someone give me directions to Leonard Ave? It's not coming up on Apple Maps. #Sunnyvale#SiliconValley#mapping#gis#maps#history
“They don’t get much in the way of posthumous glory, but Roman surveyors have left us a wealth of technical treatises, collectively known as the Corpus Agrimensorum Romanorum, which is of unique historical importance for its detailed descriptions of the nature of land settlement, and the role of emperors, especially Augustus, in regulating urban centers in a rural environment. Archaeologist David Gilman Romano, longtime director of the Corinth Computer Project, has been using the Agrimensores to understand the rural geography of Corinth and the nature of Roman re-settlement of the city… #GIS#spatial#mapping#surveying#surveyor#survey#instrumentation#ancientrome#roman#history#urban#buildings#aqueducts#roads#fortifactions#construction#engineering#design#archaeology#archaeologist
