EPSG Geodetic Parameter Dataset (also EPSG registry) is a public registry of geodetic datums, spatial reference systems, Earth ellipsoids, coordinate transformations and related units of measurement. Originally created by European Petroleum Survey Group (EPSG). Each entity is assigned an EPSG code between 1024-32767, along with a standard machine-readable well-known text (WKT) representation. The dataset is actively maintained by the IOGP Geomatics Committee. Most geographic information systems (GIS) and GIS libraries use EPSG codes as Spatial Reference System Identifiers (SRIDs) and EPSG definition data for identifying coordinate reference systems, projections, and performing transformations between these systems, while some also support SRIDs issued by other organizations (such as Esri).

Octagonal Faced Protective Cover in GeoGebra 3D Calculator
It’s not an every-day occurrence to find 3 1/4-regular-octagons w/same center & where each is orthogonal to other 2 (packing material 🙂). Given (0,0,0) = center & side = 6.4, what are possible coordinate setups for other vertices? 🤔 #GeoGebra #3d #MTBoS #ITeachMath #math #maths

Mingkun Liu - Length Partition of Random Multi-geodesics on Large Genus Hyperbolic Surfaces
On a hyperbolic surface, a closed geodesic is said to be simple if it has no self-intersection. A multi-geodesic is a multiset of disjoint simple closed geodesics. A multi-geodesic can be decomposed into connected components, and therefore induces a partition of its total length. In this t
