FINALLY! 📢
Version 10 of ESA's SNAP has been released!

But was it worth the wait? 🤔

Read in my blog what has changed and what has been added in this version.

I've used GeoPandas for a while and never known about the .cx accessor. You can use it to easily subset by a bounding box - like:

gdf.cx[xmin:xmax, ymin:ymax]

I think that'll be pretty useful! See https://geopandas.org/en/stable/docs/reference/api/geopandas.GeoDataFrame.cx.html for more details

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!)

Radar satellites can see at night and through clouds

They also can detect millimetre changes in some cases, from space (!)

But I've found them really counter-intuitive, so I spent the last 6 months working on a video explaining how they work

Got an async FlatGeobuf reader working in Python tonight (with s3, gcs, azure support) via geoarrow-rust!

This will support bounding-box queries as well, directly from remote files.

@geojulien Thanks for reading. Yes that is an option, I think this sums up that https://www.bostongis.com/blog/index.php?/archives/271-New-in-QGIS-3.2-Save-Project-to-PostgreSQL.html In my case (for the client I worked for) we didn't have PostgreSQL and this was a 'simple' solution.

New blog post. 'Managing a master #QGIS project (with a .bat file)'. Use a master project, but not change it. Give a copy to each person on the desktop with a .bat file http://www.acgeospatial.co.uk/managing-a-master-qgis-project-with-a-bat-file/

📢 OGC is seeking public comment on the adoption of openEO as a Community Standard. openEO aims to increase the interoperability of processing “big EO data” (e.g. satellite imagery) in the cloud by defining a simple an unified API.

Search and acquire any satellite images with just a few lines of code in R!

Finding Geospatial Accounts on Mastodon

Besides following hashtags, such as #GISChat, #QGIS, #FOSS4G, #openstreetmap and #OSGeo, curating good lists is probably the best way to stay up to date with geospatial developments. To get you started (or to potentially enrich your existing lists), I thought I'd share my #Geospatial and #SpatialDataScience lists with you.

Jupyter + Quarto = easy scientific and technical publishing!

At #JupyterCon, J.J. Allaire shared how the two work together to easily create and share the output format (HTML, PDF, Microsoft Word, reveal.js) and the styling you need for any situation.

There are so many features that make scientific and technical publishing an actual joy. Check out his talk to hear more! #Python #Quarto
