EPSGlide 0.2.1

Efficient great circle computation and projection library with access to EPSG dataset public API

Python epsglide package

This package aims to perform simple requests to EPSG GeoRepository API and provides associated geodesic computation and map projection.

EPSG dataset requests and projection

>>> import math, epsglide
>>> crs = epsglide.ProjectedCoordRefSystem(26730)
>>> crs
<ProjectedCoordRefSystem 26730: NAD27 / Alabama West>
>>> point = epsglide.Geodesic(math.degrees(crs.lambda0), math.degrees(crs.phi0))
>>> crs(point)
<US survey foot:3.281[X=152400.305 Y=0.000] alt=0.000>
>>> crs(crs(point))
<lon=-087d18m0.00000s lat=+030d00m0.00000s alt=0.0>

Great circle computation

>>> wgs84 = epsglide.dataset.Ellipsoid(7030)
>>> dublin = epsglide.Geodesic(-6.272877, 53.344606, 105.)
>>> london = epsglide.Geodesic(-0.127005, 51.518602, 0.)
>>> dist = wgs84.distance(dublin, london) 
>>> dist
<464.572km initial bearing=113.5° final bearing118.3°>
>>> wgs84.destination(dublin, dist) 
<lon=-000d07m37.21798s lat=+051d31m6.96719s end bearing=118.3°>
>>> london
<lon=-000d07m37.21800s lat=+051d31m6.96720s alt=0.0>
