The good news: #DuckDB now includes #Geometry as a built-in type, a major step forwards for this #database engine.

The bad news: it stores #Geographic #Coordinates backwards, with #longitude first. Beware of interoperability with other software.

Geometry Data Type

Name Description GEOMETRY Geospatial entity The GEOMETRY data type is used to store and manipulate geometric objects, such as points, lines, and polygons. The GEOMETRY type was part of the spatial extension but became a built-in data type in DuckDB v1.5. Most of the benefits of having GEOMETRY as a built-in type (e.g., storage optimizations, statistics, etc.) are therefore only available in databases using storage version v1.5 and above. However, almost all of the associated functions for working with geometries (e.g., calculating distances, areas, intersections) are still part of spatial. Types of Geometries Conceptually, the GEOMETRY type follows the core…

Yes and I think it’s about time for Britannia to start ruling the waves once more too.

Seriously though, I did enjoy visiting #Greenwich and seeing all the brave attempts at creating an accurate clock to determine #longitude, on display. Amazing that the winning design adopted was so compact too!

A pendulum! This jogs my brain to an apparently-random #memory, likely from #JamesBurke's #TheDayTheUniverseChanged series, about how #latitude was easy to determine via the skies, but that #longitude could not be measured until timepieces that did NOT require a #pendulum to drive it were invented.

Pendulum movement isn't very functional on a rolling #ship, after all.

And at that moment, the name of the item
I held and it's purpose snapped vividly to mind: it was a #sextant!

Reverse geocoding 的簡化

前幾天看到「Mapping latitude and longitude to country, state, or city」這篇,應該是在 Lobsters 看到的... (不是很確定) Reverse geocoding 是指輸入經緯度,反推出在哪個區域 (國家/州/城市): An app can easily check a user's location (with permission), but figur...
