Good set of posts here on the differences between odc-stac and stackstac for merging multiple STAC items into xarray datasets: https://discourse.pangeo.io/t/comparing-odc-stac-load-and-stackstac-for-raster-composite-workflow/4097

Cool looking new STAC CLI - see https://github.com/stac-utils/stac-rs/tree/main/stac-cli

Lets you create STAC items, search STAC APIs, validate STAC items etc.

Philadelphia’s Hidden Etymologies [map]

https://en.wikipedia.org/wiki/List_of_Philadelphia_placename_etymologies <-- Wikipedia page

[fascinating stuff, I love place and people etymologies, especially displayed with such good cartography – and I don’t even know Philadelphia!]
“This is a list of the sources of some of the place names in the city of Philadelphia, Pennsylvania…”

GeoPandas has released an alpha of v1.0.0 - time to check it works with your code.

Details at https://martinfleischmann.net/geopandas-1.0-is-coming.-what-will-change/, changes include switching default loader from fiona to pyogrio (nice! I often forget to use pyogrio and it'll save me time), requiring Shapely 2.0, removing built-in datasets, and deprecating some stuff.

Spatiotemporal Analysis Is 17,000 Years Old – Or Maybe More?

https://subscription.packtpub.com/book/programming/9781837639175/2/ch02lvl1sec05/history-of-geospatial-analysis <-- shared text

https://doi.org/10.1017/S0959774322000415 <-- shared paper

[Snow and Picquet were not first, as amazing as they were...]
“Geospatial analysis can be traced back as far as 17,000 years ago [or more], to the Lascaux cave in southwestern France. In this cave, Paleolithic artists painted commonly hunted animals and what many experts recently concluded are dots representing the animals’ lunar cycles to note seasonal behavior patterns of prey, such as mating or migration…”

We just published an exciting new article exploring the capabilities of OpenStreetMaps (OSM) and the Overpass API designed for querying its data.

Fascinating mapping going on here in South Dakota in OpenStreetMaps. #gis

On examination, this is apparently the Rosebud Indian Reservation, which has been shattered into a million different pieces. There's got to be some history to that. (I suspect, probably some trickery/abuse on the part of the US related to supression of Native Americans, but I may be wrong) https://www.openstreetmap.org/way/9869788#map=14/43.4802/-100.5684 #gis #mapping #SouthDakota

Aha, yes... "One hundred years ago homesteaders began buying land that was formerly part of American Indian reservations.. The Rosebud Reservation was opened in 1904 after many years of negotiations with the federal government.... Many tribal members never saw the money, but lost the land....The Lakota were left with a disaster, a checker-boarded reservation and land issues that still plague them today. Most reservations in South Dakota were opened to homesteading, all are checker-boarded within the boundaries with land owned by non-Indians, tribal members, the tribes and much lease and fee land."

It appears my Tiger geocoder isn't working well. Points aren't even being geocoded to the same street. I've even used the address standardizer function before passing them into the geocoder but it doesn't help. The address standardizer output looks great, too!

Anyone have any ideas?

Got data surfing?

Here is a video I made showing how to use the web map GISsurfer (I am dev) to split your screen and ‘surf’ data on any ArcGIS server with a public table of contents.

https://youtu.be/IW818LwkBlY

Drill down to a layer on the left side of the screen, click the layer and that data appears on the map on the right side of your screen. You might need to zoom in/out since some data only appears at certain zoom levels.

The video also shows how to make a GISsurfer link to automatically display the layers you have turned on.

For 3,000+ ArcGIS server addresses (USA) see this PDF I curate:
https://mappingsupport.com/p/surf_gis/list-federal-state-county-city-GIS-servers.pdf
