→ GBIF Geocoder: using GBIF to find places on a map
iphylo.blogspot.com/2026/02/gb

“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.”

#map #GBIF #place #geocode #locality #coordinates

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 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.

#Trump wants #Zelenskyy to show willingness to make concessions including #territorial cessions to #russia, movement toward #elections, and possibly stepping down.

Russia has intensified #attacks following the #US aid pause, making Friday one of the deadliest days for civilians this year according to UN monitors.

The US continues sharing defensive #intelligence (warning Ukraine of impending attacks) but has stopped providing offensive targeting #coordinates.

Очень люблю эту табличку и регулярно её показываю особам, бездумно копирующим координаты из Гугла

-----

I really love this table and regularly show it to people who mindlessly copy from Google

Таблица точности координатной записи с двумя столбцами, Точность и Значение: 

Без знаков после запятой: Вы находитесь где-то
1 знак: Вы в определённом городе
2 знака: Вы в определённом районе
3 знака: Вы на определённой улице
4 знака: Вы в определённом углу дома
5 знаков: Вы отмечаете определённого человека в доме, но из-за неопределённого датума мы не можем сказать, кого именно
7 знаков: Вы отмечаете иголку в стоге сена
9 знаков: Какая интересная и уникальная песчинка на пляже
14 знаков: Либо вы рандомно набиваете цифры, либо создаёте модель движения атомов в пространстве. В любом случае — остановитесь, пожалуйста!

Coordinate notation accuracy table with two columns, Accuracy and Meaning:

No decimal places: You are somewhere
1 decimal place: You are in a certain city
2 decimal places: You are in a certain neighborhood
3 decimal places: You are on a certain street
4 decimal places: You are in a certain corner of the house
5 decimal places: You are marking a certain person in the house, but because of the undefined datum we can't tell who
7 decimal places: You are marking a needle in a haystack
9 decimal places: What an interesting and unique grain of sand on the beach
14 decimal places: You are either randomly typing in numbers, or you are creating a model of how atoms move in space. Either way, please stop!

The #KrononautMoon Project is an ongoing series of community experiments to contact #TimeTravelers — as "in-person", but more likely via #quantum #signal. The next attempt is coming up soon on 14 Mar 2025 — under the #TotalLunarEclipse — wherever you are. These outreaches are sometimes referred to as "landing receptions", but call them or redesign them however you like. Following is a brief, all-true #chronology of such #events, going back 40+ years. The excerpt is from our detailed #article on Medium.com.

❛❛ #Future #intelligences would have the necessary transport #technology that is not yet existent in our #world. To date, there have been 5 recorded attempts of this method, with the most famous one devised by the late #theoretical #physicist #StephenHawking, in #Cambridge #UK on 2009 Jun 28.

Hawking referred to his get-together as a “reception”—what we now think of as a version type 1.0. His champagne toast to “tourists from the future” was, by no means, not the first of the prototypes, however, because it was staged years after 3 similar experimental attempts — stationed in different #countries and unrelated to each other. The professor’s cheeky soirée occurred four years after a rollicking party that was thrown for “Inhabitants of the Future” at Forrest Place, #Perth #AU, on 2005 Mar 31. Then, a few months later, an equally festive #TimeTraveler #Convention was hosted at #MIT — The #Massachusetts Institute of Technology, #Cambridge #MA #US, on 2005 May 07. These elaborate productions were preceded by a full two decades, back when a group identifying itself as the #Krononauts assembled in #Baltimore #MD #US (alt. spelling: #Chrononauts). That seminal event, which was covered by a #NewYorkTimes reporter, happened at a downtown #bookstore, under the light of a #FullMoon, and a multi-planetary #syzygy, on 1982 Mar 09.

More recently, in the spring of 2023, a dogged #podcaster for TheLastArchive.com and Pushkin.fm, published a riveting and droll #audio recounting of Baltimore’s Krononauts gathering, and then gave the concept a uniquely personal #experimental spin, noting the time and #GPS #coordinates. The effort successfully demonstrated that a single individual can attempt extra-temporal #contact on one’s own, equipped with little more than a #public #library #bench, and can meaningfully contribute to the corpus of #Community #Time #Travel #Research. ❜❜

On 2025 Mar 14, join your #friends, fellow #Mastodonians, and #TimeTravelers for an evening of #peace, #love, and #cosmic #tranquility, wherever you are.

It's convenient to convert Google #maps address share link to #coordinates -> simple, short to use for other, offline maps =D,
from Organic maps app.
eg: something like:
google.com/maps/place/Eiffel+T
-> 48.8583701,2.2922926
