#openlayers version 10 is released
It is a major version, but I guess the breaking changes should not affect that many applications

how the “random #geodata generator” application is built using #webassembly #wasm

Jakob Miksch · Random Geodata GeneratorFor software development, I often need different geodata sets for testing. So far, I have created these with geojson.io or QGIS or downloaded data from OpenStreetMap or Natural Earth. However, I had a use case where I needed data from specific regions. And ideally not only in WGS84, but also in the respective UTM projection for the region. Since there is no such tool to my knowledge, I wrote it myself.
Starting to look into MapLibre JS at the moment, having been a Leaflet chap until now. Quite a different style, will take me a while to get the hang of.
Found https://github.com/stevage/map-gl-utils which looks pretty nice - probably should learn the standard way of doing it first, but this seems to make things much easier.

#HurricaneHilary interactive #GIS map. When the map opens the layer with NOAA’s forecast discussion is on top. Click inside any red-outlined area and follow the link. Screenshot from #SanDiego area discussion.
Map has *lots* of weather layers you can turn on but only the ‘top’ layer is clickable. For help please read the “Map tips” link in the upper left corner.
