An unfortunate reality of our moment is that (1) lots of us feel powerless to help deal with the various disasters floating around us and (2) there are lots of such disasters, often so bad they impact our physical (mapped) world.

A small but significant way to help is updating Open Street Map, since it is used by emergency teams around the world; here’s links to emergency mapping going on in Alaska, Maui, and Vermont right now: https://lists.openstreetmap.org/pipermail/talk-us/2023-August/022052.html

The downsides of being frugal.

The #OpenStreetMap Foundation spends, even with a slightly more ambitious budget this year than previously, less than %1 of what WMF/Wikipedia does, but is struggling to make ends meet.

There is no threat a la the infamous Wikipedia ads that the project will shut down, but without the funds activities will have to be cut back significantly.

This week's #Geogeeks evening on Wednesday (5 July) will have another three short talks:

* Ben Ritter: #OpenStreetMap’s big forking problem: OSM centrelines to full streets.
* Julien Perret: Towards the harmonization of digital field data entry for geological mapping: an in-house #QGIS #QField based template.
* Mark Jessell: Delivering data using #GeoServer with #TerriaMap and custom systems.

Newsprint / halftone render in :qgis: .

Used a hex grid and the 'overlap analysis' tool to work out percentage overlap of grid cells/land. Dots then scaled in proportion to overlap

Using coastal data copyright #openstreetmap contributors

Performance tips: use 'subdivide' on land, buffer inward 1m (fixes geometries), split to singlepart, add spatial indexes to both layers. Now takes minutes, not hours
