→ GBIF Geocoder: using GBIF to find places on a map
https://iphylo.blogspot.com/2026/02/gbif-geocoder-using-gbif-to-find-places.html

“The idea behind the "GBIF Geocoder" is that GBIF has a huge number of geocoded specimens, and hence if you are looking for coordinates for a locality there is a good chance that somebody has already found them. So, all we need to do is search GBIF for specimens with localities that match the place you are trying to geocode.”

I'm an #engineer, not an #artist. But every so often, I need to use graphics-related tools for something I'm working on. Today's example was trying to lay out some control panel #graphics, and I was using #Inkscape on #Debian.

What I did: created a circular object

What I wanted to do: when I select that object and type values into the #coordinates boxes, the circular object moves so that its *center* is at the specified coordinates.

What Inkscape actually does: moves the object so the top-left corner of the object's bounding box is at those coordinates.

Really not helpful when you want to #align multiple objects to the same #center.

Do some searching, find #forum posts of others asking how to do this exact thing. Answers range from "select the object and open the #XML editor..." to "do this specific thing which doesn't appear to have existed in the UI for a decade", to people suggesting workarounds (you need a #workaround for what must be an *extremely* common workflow?).

One workaround: "just create a #guide, move (or maybe it was 'align') the object's something-or-other to the guide". The word "guide" does not occur in the UI, FAQ or in the basic documentation for Inkscape. Searching for it is troublesome because of all the web pages that have "guide" in their *title* rather than their content.

Lots of other discussions with links to pages on the Inkscape site which are now 404.

Where's that "FFFFUUUUUUUU..." meme when I need it?

For the nineteenth #30MapsInAMonth are a set of map using different coordinate system projections of Natural Earth railway data https://www.naturalearthdata.com/

The four maps represent points on the oblate-spheroid that is the Earth on a surface. The first uses latitude and longitude in °, the rest are in meters. The second is commonly used on the web, the third a projection for Europe and the final is the UK Ordnance Survey map projection.

#Rotating a #Point about the origin, through some #Angle θ is something that is taught in school #maths class, usually in #CartesianCoordinates, by multiplying the #Coordinates by a the rotation #Transformation #Matrix. What’s not generally taught is that you can apply the same transformation to any #Function y=f(x). All you need to do is replace
x by xcosθ + ysinθ
and y by -xsinθ+ysinθ.
