In #foss4ge2025 I was talking about Mercator projection, and what is the difference with "Web-Mercator"

These images (at different zoom levels) show a loxodromic curve (at 45° N) in Web-Mercator (EPSG:3857) - that is a straight line in Mercator (EPSG:3395). In red the loxodromic or rhumline. In blue a straight line connecting the endpoints.

(To reproduce it in #QGIS, deselect "Clip features to canvas extent" for the affected layers as discussed in github.com/qgis/QGIS/issues/62)

I presented #Mapbender at the #FOSS4GE2025 conference in Mostar & demonstrated how you can create great geoportal applications with Mapbender & talked about the news.

I also introduced #QGIS2Mapbender - a #QGIS plugin that publishes your QGIS Project as QGIS Server WMS & also in a Mapbender application.

Animation visualising the speed of an Edinburgh tram journey from Newhaven to Edinburgh Airport (the full route)

Time scale is approximately 1 sec of animation to 1 minute real time, the whole trip took about an hour.

Red is slow, yellow is fast. Speeded up a lot past Haymarket, when the tracks diverge from the road network.

Used data copyright #OpenStreetMap contributors in QGIS to snap the points to route
